Description

Description Title of the invention: Packaging containing fibers natural absorbents

[0001] DOMAIN

[0002] — This description relates to packaging for absorbent articles, more particularly packaging with natural fibers.

[0003] BACKGROUND

[0004] — Consumer demand for products manufactured at least partially from renewable resources has increased significantly over the past few years decades past, and has become a driving force for innovation in products consumption and new and improved packaging materials. In this respect, increasing emphasis is being placed on packaging products and materials including renewable resources. For example, there is strong interest in the market for consumer products that include natural materials and bio-based materials, recyclable materials, recycled materials, and / or materials biodegradable.

[0005] — Compressible, non-fragile consumer products, such as ab- disposable absorbents (e.g., baby diapers and training pants) For hygiene, disposable incontinence briefs for adults and sanitary pads feminine hygiene products) are often packaged and sold at retail (i.e., displayed and intended for sale in a retail store) in packaging flexible materials made from a plastic polymer film. Plastic is preferred as primary packaging of consumer products because plastic can to withstand the rigors of a conditioning process, given the capacity of the plastic to flex and stretch, while materials comprising more resources Renewable fibers, such as natural fibers, can be prone to wrinkling, to cracking and tearing in similar packaging processes. Furthermore, Because plastic can flex and stretch without easily tearing, stacks of items Absorbents can be compressed within the plastic packaging to be displayed neatly and in an orderly fashion on the shelves.

[0006] — Thus, packaging containing natural fibers for absorbent articles should be improved.

DETAILED DESCRIPTION The term "absorbent article" as used herein refers to devices that absorb and contain exudates, and, more specifically, refers to devices that are placed against or near the wearer's body to absorb and contain the various exudates excreted by the body. Absorbent articles in this description include, but are not limited to, baby diapers, adult incontinence briefs, training pants, diaper covers, menstrual pads, incontinence pads, liners, absorbent inserts, panty liners, tampons, and the like. The term "machine direction" or "MS", as used here, refers to a path that the material, such as a packaging material, follows through a manufacturing process. The term "transverse direction of the machine" or "ST" as used here, refers to a trajectory that is perpendicular to the direction of the machine in the plane of the material. The term "natural fibers," as used here, refers to fibers that include cellulose-based fibers, bamboo fibers, and the like. Natural fibers also refer to: non-wood fibers, such as cotton, abaca, Java jute, Chinese alpine rush, flax, esparto grass, straw, hemp jute, bagasse, milkweed fibers, and pineapple leaf fibers; and wood fibers, such as wood or paper pulp such as those obtained from hardwoods and softwoods, including softwood fibers, such as kraft fibers from northern and southern softwoods, and hardwood fibers, such as eucalyptus, maple, birch, and aspen.Paper pulp fibers can be prepared in high-yield or low-yield forms and can be reduced to paper pulp by any known process, including high-yield kraft pulping, sulfite pulping, and other known pulping processes. The natural fibers described herein may be recycled natural fibers, virgin natural fibers, or mixtures thereof. Furthermore, for good mechanical properties in natural fibers, it may be desirable for the natural fibers to be relatively undamaged and widely spaced. unrefined or only slightly refined. The fibers may have a Canadian Standard drain index of at least 200, more specifically at least 300, more specifically at least 400, and most specifically at least 500. The term "cellulose-based fibers," as used here, may include regenerated cellulose fibers such as rayon or copper-ammonium rayon, and high-yield pulp-reduction fibers, unless otherwise specified. The term "cellulose-based fibers" also includes chemically treated natural fibers, such as mercerized pulp, chemically stiffened or crosslinked fibers, or sulfonated fibers. Also included are mercerized natural fibers, regenerated natural cellulosic fibers, microbially produced cellulose, the rayon process, cellulose dissolution-coagulation spinning processes, and other cellulosic materials or cellulosic derivatives. Other included cellulose-based fibers are paper scraps or recycled fibers and high-yield pulp fibers.High-yield pulp fibers are those fibers produced by pulping processes that provide a yield of approximately 65% ​​or more, more specifically approximately 75% or more, and even more specifically from approximately 75% to approximately 95%. Yield is the resulting quantity of processed fiber expressed as a percentage of the initial wood mass. Such pulping processes include bleached chemothermal pulp (BCTMP), chemothermal pulp (CTMP), pressure / pressure thermomechanical pulp (PTMP), thermomechanical pulp (TMP), chemical thermomechanical pulp (TMCP), high-yield sulfite pulp, and high-yield Kraft pulp, all of which leave the resulting fibers with high levels of lignin but are still considered natural fibers.High-yield fibers are well known for their stiffness in both dry and wet states compared to typical fibers reduced to paper pulp by chemical process. The packaging described herein comprises a packaging material containing a plurality of absorbent articles, whereby the packaging material comprises or is derived from natural resources. Specifically, the packaging material described herein comprises natural fibers. The natural fibers may form a paper from which the packaging material is manufactured. The composition of packaging materials is discussed in more detail here. Matéri iti The packaging materials in this description include fibers natural. The conditioning materials of this description may include wood fiber and / or pulp fiber. The conditioning materials may comprise at least 50 percent by weight of natural fibers, at least 70 percent by weight of natural fibers, at least 90 percent by weight of natural fibers, between about 50 percent and about 100 percent by weight of natural fibers, between about 65 percent and about 99 percent by weight of natural fibers, or between about 75 percent and about 95 percent by weight of natural fibers, specifically citing all values ​​within these ranges and all ranges formed within them. In one form, the conditioning materials may comprise 99.9 percent by weight of natural fibers. Inks, dyes, and / or other colorants associated with the packaging technique, marking, packaging information, and / or background color, as well as adhesives associated with seams and protective coatings, are also considered part of the packaging materials on a weight percentage basis. When the weight percentage of natural fibers is less than 100 percent, the difference may consist of inks, dyes, and / or adhesives. Dyes, coatings, and adhesives may be considered contaminants in a paper recycling process. While packaging materials can include many different fibers, dyes, coatings, adhesives, etc., the packaging material described here can be formulated to facilitate and / or encourage recycling, and can encourage recycling within a single recycling stream, such as a paper recycling stream. Whether packaging materials are recyclable may vary from region to region.To meet one of the highest recyclability standards, the total weight percentage of non-recyclable material, including material that is not recyclable within a particular recycling stream—such as a paper recycling stream—but that may otherwise be recyclable, for example, dyes, adhesives, and coatings in the packaging material, may be 5 percent by weight of the packaging material or less, or from 0.1 percent to 5 percent by weight, specifically citing all values ​​within these ranges and all ranges formed within them. However, other jurisdictions may allow a higher weight percentage of non-recyclable material.The packaging material of this description may comprise 50 percent by weight or less, 30 percent by weight or less, 15 percent by weight or less, or 10 percent by weight or less of non-recyclable material, specifically including all values ​​within these ranges and all ranges formed within them. these or as a result. By way of another example, the packaging materials in this description may comprise between about 0.1 percent and about 50 percent by weight, from about 0.1 percent to about 30 percent by weight, or from about 0.1 percent to about 15 percent by weight of non-recyclable material, specifically including all values ​​within these ranges and all ranges formed within them or as a result. The packagings described herein may include dyes, coatings, and / or adhesives in a combined weight percentage of less than 30 percent, 20 percent, or 10 percent of the total packaging weight. The packagings described herein may also include dyes, coatings, and / or adhesives in which the combined weight percentage of dyes, coatings, and / or adhesives may be between approximately 0.1 percent and approximately 30 percent, preferably from approximately 0.1 percent to approximately 20 percent, and more preferably from approximately 0.1 percent to approximately 10 percent, by weight of packaging, specifically citing all values ​​within these ranges and all ranges formed within or by virtue of them. The packaging materials described herein may be free of a barrier layer. As used here, the term "barrier layer" refers to a layer of material, including barrier coatings, barrier plastics, and / or barrier metal foils, that is attached to packaging materials containing natural fibers. Such barrier layers may reduce the recyclability of packaging materials within a single recycling stream. In other cases, to at least partially protect absorbent articles within the packaging, the packaging materials described herein may include a barrier layer. This barrier layer may at least partially inhibit the migration of water vapor through the packaging material. The barrier layer may comprise a water-soluble material that may not interfere with a recycling process. The barrier layer may be easily separable from the rest of the packaging materials through a recycling process, for example, by having different water solubility, density, buoyancy, or other physical characteristics compared to the rest of the packaging materials. The type of adhesive used for the seals of the packaging described herein can also influence the packaging's recyclability. For example, adhesives that can dissolve in water during the pulping stage of the paper recycling process may These adhesives are particularly suitable for the packaging described herein. Such adhesives include starch-based adhesives, polyvinyl acetate-based adhesives, and polyethylene oxide-based adhesives. A suitable example of a starch-based adhesive is available from LD Davis, located in Monroe, North Carolina, under the brand name AP0420CR. A suitable example of a polyvinyl acetate-based adhesive is available from Sekisui Chemical Company, located in Osaka, Japan, under the brand name Selvol 205. A suitable example of a polyethylene oxide-based adhesive is available from Dow Chemicals Co., located in Midland, Michigan, under the brand name WSR N-80. Water-dispersible adhesives can be used similarly. Suitable examples of water-dispersible adhesives include thermoplastic elastomer-based adhesives and polyvinyl acetate-based adhesives. A suitable example of a thermoplastic elastomer-based adhesive is available from Actega, located in Blue Ash, Ohio, under the brand name Yunico 491. A suitable example of a polyvinyl acetate-based adhesive is available from Bostik, located in Milwaukee, Wisconsin, under the brand name Aquagrip 4419U01. Another suitable example of a polyvinyl acetate-based adhesive is available from HB Fuller under the brand name PD-0330. Without being bound by any particular theory, it is thought that packaging described herein that uses water-soluble adhesives may contain a higher weight percentage of such adhesives than adhesives that are only water-dispersible. For example, packaging containing water-soluble adhesives may contain a first weight percentage of adhesive, while packaging containing water-dispersible adhesives may contain a second weight percentage of adhesive. The first weight percentage may be greater than the second weight percentage for the purpose of recycling the packaging material. When a barrier layer is used, the barrier material can be chosen to reduce or eliminate the need for adhesives. Such a barrier material can be a polyethylene film coated onto an internal surface of the packaging material. Polyethylene can be used to form the seals instead of, or in conjunction with, an adhesive. However, because the polyethylene film may not be recyclable in the same stream as other packaging materials, the weight percentage of polyethylene can be adjusted according to the present description of non-recyclable material percentages discussed here. The effectiveness of the recycling process on the packaging material described herein can be determined by means of a recyclable percentage. The packaging material described herein may exhibit Recyclable percentages of 60 percent or more, 75 percent or more, or 90 percent or more, specifically citing all values ​​within these ranges and all ranges formed within them. The packaging material of this description may have a recycling percentage between approximately 60 percent and approximately 99.9 percent, between approximately 75 percent and approximately 99.9 percent, or between approximately 90 percent and approximately 99.9 percent, specifically citing all values ​​within these ranges and all ranges formed within them. In a specific example, the packaging material of this description may have a recycling percentage between approximately 95 percent and approximately 99.9 percent, specifically including all values ​​within these ranges and all ranges formed within them.The recyclable percentage of the packaging material in this description is determined by means of the PTS-RH:021 / 97 test (Draft Oct. 2019) under category II, as carried out by Papiertechnische Stiftung located at Pirnaer Strasse 37, 01809 Heidenau, Germany. In addition to the recyclable percentage, the total rejection percentage can be determined using PTS-RH:021 / 97 (Draft Oct. 2019) under the Category II test procedure. The total rejection percentage of the packaging material described herein can be 40 percent or less, 30 percent or less, or 10 percent or less, specifically including all values ​​within these ranges and all ranges formed therefrom. For example, the total rejection percentage of the packaging material described herein can be from approximately 0.5 percent to approximately 40 percent, from approximately 0.5 percent to approximately 30 percent, or from approximately 0.5 percent to approximately 10 percent, specifically citing all values ​​within these ranges and all ranges formed therefrom. It is believed that the percentage of non-recyclable material does not necessarily have a 1:1 correlation with the total percentage of rejects. For example, soluble adhesives and / or coatings are designed to dissolve during the recycling process. The theory is that these adhesives may not impact the total percentage of rejects; however, they would contribute to the percentage by weight of non-recyclable material. The PTS-RH:021 / 97 (Draft Oct. 2019) under the Category II test process also includes a visual component. Trained scanners inspect one or more molds of recycled packaging material for visual imperfections. If the number of visual imperfections is too high, the packaging material is rejected. If the number of visual imperfections is acceptable, in accordance with the PTS-RH:021 / 97 (Draft Oct. 2019) under the Category II test process, the packaging material is approved for further processing. additional. The conditioning material described herein may produce an acceptable level of visual imperfections during this stage of the process. The packaging material described herein can achieve the recyclable percentages mentioned above and pass the visual scanning process. Therefore, the packaging material described herein can achieve an overall rating or final result of "pass" when submitted to PTS-RH:021 / 97 (Draft Oct. 2019) under the Category IT test procedure. It should also be noted that there is an alternative method for determining the recyclable percentage of the packaging material described herein. The test method performed by Western Michigan University, called the Pulp Regeneration Test Method, can provide a percentage yield of recyclable material. While there are subtle differences between the Pulp Regeneration Test Method performed by Western Michigan and PTS-RH:021 / 97 (Draft Oct. 2019) under the Category II test method, it is believed that the percentage yield of the Pulp Regeneration Test Method would be similar to the recyclable percentage provided by the PTS test method. It is envisaged that the packaging material described herein, while being recyclable, may itself contain recycled material. Such a determination can be made through a visual inspection of the packaging. For example, manufacturers typically advertise the use of recycled materials in an attempt to demonstrate their environmentally friendly product approach. To further illustrate this point, some manufacturers may use a logo, such as a foil, along with text to indicate the use of recycled materials in the packaging material. Often, manufacturers may also specify the percentage of recycled material used, for example, more than 50 percent, more than 70 percent, and so on. A visual inspection can be as simple as using the human eye to inspect packaging for recycled material logos. In addition, or as an alternative, a visual inspection can include microscopy techniques such as optical microscopy, scanning electron microscopy, or other suitable techniques known in the art. For example, packaging material containing recycled paper fibers may appear different under a microscope due to the presence of a much wider range of natural fiber types than if the packaging material were made of 100% non-recycled paper. As another example, under a microscope, recycled fibers—due to their increased processing—may appear more fibrillated than their virgin fiber counterparts. Partly due to the use of natural fibers and limitations on their use If the packaging material contains non-recyclable materials (including materials not recyclable in the paper recycling stream but otherwise recyclable), such as dyes, adhesives, and coatings, the packaging described herein may have a less glossy or more matte appearance compared to packaging containing plastic, for example. A less glossy or more matte appearance is thought to attract consumers' attention on store shelves and / or signal to consumers that the packaging described herein contains renewable resources. The packaging described herein may have a gloss level of less than 70 GU at 60°, between approximately 10 and approximately 70 GU at 60°, between approximately 10 and approximately 60 GU at 60°, or between approximately 10 and approximately 50 GU at 60°, depending on the gloss measurement test procedure described herein.The packagings described herein may have a gloss level of less than 10 GU at 85°, between approximately 5 and approximately 10 GU at 85°, or between approximately 7 and approximately 10 GU at 85°, depending on the gloss measurement test procedure described herein. In order to withstand the rigors of a high-speed manufacturing process where a plurality of absorbent articles are arranged within the packaging, to resist the force of compressed absorbent articles being placed directly into the packaging without intermediate packaging or receptacle, to withstand the rigors of shipping, to provide protection against environmental aggressions during shipping and while on store shelves, and to ensure product protection in consumers' homes, packaging materials may have a certain level of strength, stretch, and / or resilience.The packaging materials described herein can be characterized using metrics such as: tensile strength in the SM (semi-synthetic) in kkN / m, tensile strength in the ST (synthetic) in kN / m, elongation at break in the SM (in percent), elongation at break in the ST (in percent), burst strength in kPa, thickness in µm, tensile energy absorption in the SM in J / m², tensile energy absorption in the ST in J / m², and mass per unit area in grams per square meter. While all metrics can be used together to characterize the packaging materials described herein, it is believed that some metrics, alone or in combination with others, may be sufficient to characterize packaging materials suitable for packaging absorbent articles.As an example, burst strength is thought to be able to be used alone or in conjunction with other metrics to obtain packaging materials that are sufficient for packaging absorbent articles. Similarly, tensile energy absorption (TEA) in SM and ST is thought to be able to be used in conjunction with other metrics. These metrics, and if desired, in conjunction with any combination thereof, can be used to obtain packaging materials suitable for packaging absorbent articles. As yet another example, it is envisaged that the tensile strength at break in the SM and / or the tensile strength at break in the ST can be used in conjunction with at least one of the tensile strength in the SM or the tensile strength in the ST, respectively, to characterize packaging materials sufficient for packaging absorbent articles as described herein. Any appropriate combination of metrics may be used. The conditioning materials described herein may exhibit a tensile strength in the SM of at least 5 kN / m, at least 7 kN / m, or at least 8 kKN / m, specifically citing all values ​​within these ranges and all ranges formed within them. The tensile strength in the SM may be between approximately 5 kN / m and approximately 8.5 kKN / m, between approximately 5.2 N / m and approximately 8.2 kKN / m, or between approximately 5.5 kN / m and approximately 8.0 kKN / m, specifically citing all values ​​within these ranges and all ranges formed within them. The tensile strength in the SM is measured using the tensile strength test procedure described herein. The packaging materials described herein may exhibit a tensile strength in the ST of at least 3 kN / m, at least 4 kK / m, or at least 5.5 kN / m, specifically citing all values ​​within these ranges and all ranges formed within them. The tensile strength in the ST may be between approximately 3 kK / m and approximately 6.5 kN / m, between approximately 3 N / m and approximately 6.2 kK / m, or between approximately 3 kN / m and approximately 6 kN / m, specifically citing all values ​​within these ranges and all ranges formed within them. The tensile strength in the ST is measured using the tensile strength test method. The packaging materials of this description may have a burst strength of at least 200 kPa, at least 250 kPa, or at least 550 kPa, specifically citing all values ​​within these ranges and all ranges formed within them. The burst strength of the packaging materials of this description may be between approximately 200 kPa and approximately 600 kPa, between approximately 220 kPa and approximately 550 kPa, or between approximately 250 kPa and approximately 500 kPa, specifically citing all values ​​within these ranges and all ranges formed within them. Burst strength is measured using the burst strength test procedure described herein. It is believed that the burst strength, As measured, it includes components of strength, flexibility, and resilience. Therefore, burst strength is considered to be usable independently of the other measurements mentioned. The conditioning materials of this description, in addition to strength, may also exhibit some measure of resilience. Thus, the conditioning materials of this description may exhibit a stretch at break in the ST of at least 3 percent, at least 4 percent, or at least 6 percent, specifically citing all values ​​within these ranges and all ranges formed within them. The conditioning materials of this description may exhibit a stretch at break in the SM of between approximately 3 percent and approximately 6.5 percent, between approximately 3.2 percent and approximately 6.2 percent, or between approximately 3.5 percent and approximately 6 percent, specifically citing all values ​​within these ranges and all ranges formed within them.The stretch at break in the SM is measured using the tensile strength test procedure described here. The conditioning materials described herein may exhibit a stretch at break in the ST of at least 4 percent, at least 6 percent, or at least 9 percent, specifically citing all values ​​within these ranges and all ranges formed within them. The conditioning materials described herein may also exhibit a stretch at break in the ST of between approximately 4 percent and approximately 10 percent, between approximately 4.5 percent and approximately 9.5 percent, or between approximately 5 percent and approximately 9 percent, specifically citing all values ​​within these ranges and all ranges formed within them. The stretch at break in the ST is measured using the tensile test procedure described herein. Regarding size, the packaging materials of this description may have a size of at least 50 µm, at least 70 µm, or at least 90 µm, specifically citing all values ​​within these ranges and all ranges formed within them. The packaging materials of this description may have a size from approximately 50 µm to approximately 110 µm, from approximately 55 µm to approximately 105 µm, or from approximately 60 µm to approximately 100 µm, specifically citing all values ​​within these ranges and all ranges formed within them. Size is measured using the size test procedure described herein. Regarding tensile energy absorption (TEA), the conditioning materials of this description may exhibit a TEA in the SM of at least 150 J / m°, greater than 170 J / m°, or at least 180 J / m°, specifically citing all values ​​within these ranges and all ranges formed at within these or as a result. The conditioning materials of this description may have an AET in the SM of between about 100 J / m? and about 250 J / m?, between about 125 J / m° and about 225 J / m?, or between about 150 Jm? and about 200 J / m?, specifically citing all values ​​within these ranges and all ranges formed within them or as a result. The conditioning materials described herein may have an AET in the ST of at least 150 J / m², at least 200 J / m², or at least 250 J / m², specifically citing all values ​​within these ranges and all ranges formed within them. The conditioning materials described herein may have an AET in the ST of between approximately 150 J / m² and approximately 275 J / m², between approximately 175 J / m² and approximately 260 J / m², or between approximately 200 J / m² and approximately 250 J / m², specifically citing all values ​​within these ranges and all ranges formed within them. The AETs in the SM and ST are measured according to the tensile strength test procedure described herein. The basis weight of packaging materials can affect the "feel" of the packaging to the consumer, as well as its strength. Too low a basis weight and the packaging may seem too fragile. Too high a basis weight and the packaging may seem too rigid. The packaging materials described herein have a basis weight between approximately 50 g / m² and approximately 120 g / m², between approximately 55 g / m² and approximately 115 g / m², or between approximately 60 g / m² and approximately 110 g / m², specifically citing all values ​​within these ranges and all ranges formed within or by them. The basis weight, also referred to as "basis weight," is determined according to the basis weight test procedure described herein. It should be noted that for high-speed packaging processes, the lower mass density of 50 g / m² may present some quality assurance challenges. It is believed that high-speed packaging processes can induce deformation in packaging materials that slower processes cannot. For this reason, when packaging materials are processed using a high-speed manufacturing process, 60 g / m² may be the lowest desirable mass density. When packaging materials are processed using a hand-packing or low-speed packaging process, 50 g / m² may be sufficient as the lowest mass density. The packaging materials described here are different from cardboard. For example, cardboard is not as flexible as the packaging materials... The cardboard is inherently more rigid than the packaging materials described herein and does not have the same suitability for processing on high-speed processing lines as the packaging materials described herein. Furthermore, the cardboard has a surface density exceeding 160 g / m², which is considerably higher than that of the packaging materials described herein. Similarly, cardboard also differs from the packaging materials described herein. Cardboard has a much higher basis weight (greater than 200 g / m²) than the packaging materials described herein. Furthermore, cardboard is much less flexible than the packaging materials described herein. Cardboard materials are commonly corrugated and comprise three layers of a paper material and, as such, are structurally different from the packaging materials described herein. The packaging materials described herein have the advantage of being more flexible compared to cardboard. Another advantage is that these materials take up less space than bulkier cardboard. A further advantage of the packaging materials described herein, which can be attributed at least in part to the strength and resilience properties discussed here, is that they allow the packaged absorbent articles to be compressed within the packaging. This allows more products to fit into a smaller volume package, which can increase manufacturing efficiency. A further advantage is that a single layer of the packaging materials described herein can form the packaging described herein.The inventors have discovered that, due at least in part to the properties of flexibility, strength, and resilience of the packaging materials, the packagings of this description can be formed from a single layer (a stratum) of packaging materials of this description. Despite having less flexibility compared, for example, with plastic packaging, and a lower surface mass than cardboard, inventors have surprisingly discovered that the packaging materials of this description can withstand the rigors of a high-speed manufacturing process - where a plurality of absorbent articles are placed within the packaging under compression - as well as the rigors of shipping, provide protection against environmental aggressions during shipping, and while on store shelves, and ensure product protection in the consumer's home. Table 1 shows a variety of packaging materials that can be These materials have been successfully used to package absorbent articles under high-speed processing conditions, along with at least one packaging material that was unsuccessful. The various properties discussed previously are also listed for each sample. Sample 1: Packaging paper produced from pure white kraft paper pulp and made entirely from virgin fibers, available from BillerudKorsnäsTM under the Axello Tough White brand. Sample 2: Packaging paper produced from pure white kraft paper pulp and made entirely of virgin fibers, available from BillerudKorsnäsTM under the brand name Performance White SE. Sample 3: Specialty calendered kraft paper made entirely from virgin fibers, available from MondiTM under the Advantage Smooth White Strong brand. Sample 4: Packaging paper produced from kraft pulp, made of virgin fibers, and including a fluoropolymer barrier coating, available from BillerudKorsnäsTM under the brand name Basix Glaze.

During the placement of the absorbent article in the packaging, the packaging material tears. Without being bound by any theory, it is thought that sample 4 failed due to a combination of low surface mass and a high-speed packaging process. While sample 4 failed under the conditions of the high-speed process, it is thought that a sample with the properties of sample 4 may be successful using a more moderate packaging process, such as manual packaging. Conditioning configurations The packaging materials described herein can be arranged as a package in a myriad of configurations to contain one or more absorbent items. For example, the package may comprise a plurality of panels that define an inner compartment and enclose one or more absorbent items. When in a sealed state, such as during transport and when displayed on a store shelf, the package may completely enclose one or more absorbent items. Each panel comprises an inner surface—facing inward toward the packaged absorbent item—and an outer surface—facing outward toward the consumer. The outer and / or inner surface of one or more panels may include inks or dyes that create markings on the package, packaging information, and / or a background color.The marking and / or packaging information associated with the absorbent items within the package may be provided on at least one external panel. The marking may include logos, brands, trademarks, icons, and similar elements associated with the absorbent items within the package. A marking may be used to inform a consumer of the brand of the absorbent items within the package. For example, the marking for a package of feminine hygiene pads may include the Always® brand name. Packaging information may include the size of the absorbent items, the number of absorbent items in the package, a representative image of the absorbent items contained within the package, recyclability logos, and similar elements.As an example, packaging information for a package of feminine hygiene napkins may include a size indicator, for example, "Size 1." The packaging materials described herein may be supplied by a packaging materials manufacturer to an absorbent product manufacturer. The packaging materials may be preformed to some extent into a finished packaging shape, or the packaging materials manufacturer may The manufacturer can simply supply rolls of packaging material to the absorbent product manufacturer. The packaging material can be a single piece, meaning that a package is formed from one continuous piece of material. For example, multiple folds and seams can be used to form the multiple panels of the package from a single piece of material. In such examples, the absorbent product manufacturer can create the folds and seams as described here to form a package for absorbent products. Regardless of whether the packaging material is on rolls or preformed to some extent, the packagings described herein begin with a paper stock. With reference to Figures 1A to 1B, the edge portions 100 and 110 of a sheet of paper stock 99 can be folded towards each other and subsequently sealed to form a seam. For example, the side portions 100 and 110 of the sheet 99 can be brought inwards towards a longitudinal midline 90 of the sheet 99 to form a ring seam 95 (see [Fig. 1C]). These edge portions can overlap and be sealed together to form an overlap seam. Alternatively, the edge portions 100 and 110 can be joined together on their respective inner surfaces to form a butt seam. Butt seams tend not to lie flat like an overlap seam.For this reason, where the seam is located, at least in part, on a lower panel on which the packaging can rest, an overlapping seam may be desirable so that the packaging can rest on a flatter lower panel. Referring to Figures IC to 1E, the packaging material sheet can be folded appropriately to form lateral bag pleats 12b and 13b and two lateral folds 12a and 13a on opposite sides, to form the bag structure 4 having a first surface 10, a second and a third surface 12, 13, respectively, and a fourth and a fifth surface 14, 15. An open end 48 is opposite the first surface 10. Each lateral pleat 12b, 13b can be located at the second or third respective surface 12, 13. It should be noted that in Figures 1C and 1D, the pleat and folds shown are for packaging having a block configuration or a block bottom configuration. Gussets and fold lines for a pinch-bottom bag are discussed in more detail in [Fig. 2B]. The bag 4 can be filled by inserting items, such as a plurality of absorbent items, through the open end 48. When the bag 4 is filled with a plurality of items, for example by loading items through the open end 48, the device used to introduce the items into the bag 4, together with The articles can exert some tension on each of the second and third surfaces 12, 13 of the bag 4. For example, the articles can be compressed before being inserted into the bag 4 so that the articles can unfold slightly after being introduced into the bag 4, and thus exert some tension on the second and third surfaces 12, 13 as well as the fourth surface 14 and the fifth surface 15. The tension can be exerted on each of the pleats 12b, 13b at the level of the respective second and third surfaces 12, 13, particularly along the first and second lateral folds 12a, 13a by which the packaging can maintain a substantially parallelepiped shape. As can be seen in [Fig. 1D], the open end 48 opposite the first surface 10 can then be closed to form a sixth surface 11. Any suitable type of closure can be used. In one form, the sixth surface may include closure gussets 1b, in which portions of the outer surface of the packaging material at the closure gussets 11b are joined to form a closure seam 1la and a closure seam wing 11c extending from the closure seam 1la and the sixth surface 11. At least a portion of the closure seam wing 11c may be attached to at least a portion of the sixth surface 11. Adhesive closure of the closure seam wing 11c to at least a portion of the sixth surface may reduce the risk of unintentional opening of the packaging, ensure better adhesion, and provide a cleaner appearance on the shelf.Instead of forming closure gussets and a closure wing, the sixth surface may include seams that are joined together in a block-type or cross-type configuration, discussed further here. An example of a block-type configuration is shown in [Fig. 2A]. As shown, the first surface 10 may include block-type seams 220 and 230. The first surface 10 may include a base portion 240. A first flap of conditioning material 250 may be folded over the base portion 240. First seams 220 may be provided to attach the first flap of conditioning material 250 to the base portion 240. A second flap of conditioning material 260 may be folded over the base portion 240 and over the first flap of conditioning material 250. Second seams 230 may be provided to attach the second flap of conditioning material 260 to the base portion 240 and to the first flap of conditioning material 250. A similar embodiment may be used for the sixth surface 11 to form a closure. Another example of a type of pan sealing that can be used with the conditions described herein is the pinch-type or pinch-type configuration. Pinch bottom. An example of a pinch-type configuration is shown in [Fig. 2B]. As shown, one of the key differences between the block bottom and pinch bottom configurations is the configuration of the pleats 12b and 13b. Instead of pleats on sides 12 and 13, a pinch-type configuration includes gussets 22b and 23b on the first surface 10. In addition, in the pinch bottom configuration, the first surface 10 includes a fold line 10a, which may be absent in the block-type configuration. A similar pinch-type configuration can be used with respect to the sixth surface 11 to form a closure. Cross-type or cross-bottom-type configurations are also acceptable for sealing portions of the packaging materials described herein. An example of a cross-type configuration is shown in [Fig. 2C]. As shown, one of the key differences between the cross-type and block-type configurations is that the gussets 32b and 33b and the fold lines 12a and 13a are oriented outwards from the inside of the packaging. In a block-type configuration ([Fig. 1C]), on the other hand, the fold lines 12a and 13a on the second surface 12 and the third surface 13, respectively, are oriented inwards before filling the packaging. Because of the orientation of the gussets 32b and 33b in the cross-type configuration, filling the packaging with absorbent articles may require less energy to deploy the packaging for filling.For example, inward-facing pleats, such as a block-type configuration, would require the pleats to be moved outward before filling the packaging. Furthermore, the equipment used to guide the product into the packaging may have a reduced probability of interfering with the gussets, given their outward orientation. This can reduce the likelihood of packaging incidents or manufacturing process stoppages due to quality issues. Referring again to [Fig. 2C], similar to the block-type configuration, the first surface 10 of the cross-type configuration includes seams 320 and 330. The first surface includes a base portion 340. A first flap of packaging material 350 can be folded over the base portion 340. First seams 320 can be provided to attach the first flap of packaging material 350 to the base portion 340. A second flap of packaging material 360 can be folded over the base portion 340 and over the first flap of packaging material 350. Second seams 330 can be provided to attach the second flap of packaging material 360 to the base portion 340 and / or to the first flap of packaging material 350. A similar embodiment can be used to form the closure on the sixth surface (formed once the packaging is sealed after the initial application). place absorbent items inside it). For less bulky items, when the packaging structure is desired, a block bottom or cross bottom may be preferable, as these configurations form a flat base. However, for bulky items, pinch-type bags can be beneficial since the bulky absorbent items inside can form a stable base, allowing the packaging to stand upright. The inventors have surprisingly discovered that baby diapers may be suitable for flat-bottomed bags due to their bulky nature. Conversely, feminine hygiene products, particularly menstrual pads, may be suitable for packaging with a block bottom. Furthermore, it should be noted that block-type and cross-type packaging configurations tend to be bulkier than their pinch-type counterparts. For absorbent packaging purposes, unfilled packages may arrive pre-formed in stacks at an absorbent manufacturer. Generally, stacks of block-type and cross-type packaging will take up more space due to their bulk compared to pre-formed pinch-type configurations. The bulk of block-type and cross-type configurations can make the stacks more difficult to handle during the filling process, especially when a large number of filled packages are created per minute. In such cases, the bulk of these configurations may mean a higher frequency of stack replenishment. With further reference to Figures 1C and 1D, the first surface 10 may form at least part of the upper panel of the packaging 1. In another embodiment, the first surface 10 may form at least part of the lower panel of the packaging 1. It should be noted that if the first surface 10 includes seams, it may be desirable for the first surface 10 to form at least part of the lower panel. In this way, the seams can be concealed from view on the store shelf. The second and third surfaces 12 and 13, since they may include gussets 12b and 13b, respectively, may include at least part of a first side panel and an opposite second side panel, respectively, or vice versa. The fourth and fifth surfaces 14 and 15 may form at least part of a front panel and an opposite back panel, respectively, or vice versa.At least one of the fourth and / or fifth surfaces 14, 15, may include marking, product information and / or background color as described herein, since the front panel is generally the panel facing the consumer. However, product information and / or color. Backgrounds may not be limited to the panel facing the consumer. Any combination of the panels of the packaging described herein may include markings, product information, and / or a background color. The sixth surface 11 may form at least part of the upper panel or at least part of the lower panel of the packaging 1. When the sixth surface 11 includes closure gussets 11b, a closure seam 11a, and a closure seam wing 11c extending from the closure seam 11a, it may be desirable for the sixth surface 11 to form at least part of the upper panel. In this way, the closure gussets 1b and the closure seam wing 11c do not introduce bulk and instability at the base of the packaging.When the sixth surface 11 forms at least part of the upper panel, an upper edge region 11d is formed at the transition from the upper panel to the front, rear, and first and second side panels. The upper edge region 11d can be formed by parts of the upper, front, rear, first, and second side panels that are adjacent to a fold in the packaging material denoting a transition from the upper panel to another panel. At least three of the packaging panels may be seamless. With reference to [Fig. 17], the back panel 15 may include a portion of a ring seam 95 that runs across the back panel 15, generally longitudinally, from the top panel 11 to the bottom panel 10. The ring seam 95 may also run through at least a portion of the top panel 11 and the bottom panel 10. The front panel 14, the first side panel 12, and the second side panel 13 may each be seamless. Such a configuration can be advantageous because it can provide three contiguous panels—front panel 14, first side panel 12, and second side panel 13—for presenting the markings and information to the consumer without the interruption of a seam in the panels. This can be particularly useful when the front panel is the panel facing the consumer. With further reference to [Fig.17], the ring seam 95 can be an overlap seam, in which edge parts of the packaging material can overlap and be sealed together, with the outer surface of one edge part facing the inner surface of the other edge part, to form an overlap seam. Other forms of packaging are considered. Examples of such packaging include a tubular envelope or a horizontally filled and sealed envelope. Such packaging may include a generally cuboid shape also configured as described previously. However, in some cases, as shown in [Fig. 18], a tubular envelope packaging 1700 may include a first surface 1702 and a second Opposite surface 1704. Rounded edges may be provided as a transition between the first surface 1702 and the second surface 1704. Alternatively, one or more fold lines may be provided between the first surface 1702 and the second surface 1704. Tubular packaging 1700 may further include end seals 1706 and 1708, and a ring seam 1709 which may be disposed on the second surface 1704. In such packaging, the first surface 1702 may include the pane facing the consumer. Tubular packaging may be useful, particularly when a small number of absorbent items are included in a package. Another form of packaging following this description may include seams / joints that are more open than those packagings comprising a block bottom, a pinched bottom, and / or a cross bottom. With reference to In Figures 19A and 19B, a 1800 conditioning unit is shown. The 1800 conditioning unit can be configured in a generally cuboid shape. The 1800 conditioning unit can include a first panel 1811, opposing second and third panels 1812 and 1813, opposing fourth and fifth panels 1814 and 1815, and a sixth panel 1810 opposite the first panel 1811. As shown, between the fourth panel 1814 and the sixth panel 1810, a first joint 1820 extends outward. The first joint 1820 can form a kind of foot for the 1800 conditioning unit. A second joint can extend outward between the fifth panel 1815 and the sixth panel 1810 in a manner analogous to the first joint 1820. The first joint 1820 can be extended such that part of the first joint 1820 is on the second panel 1812 and another part of the first joint 1820 is disposed on the third panel 1813. Similarly, part of the second joint can be disposed on the second panel 1812 and another part can be disposed on the third panel 1813. The first joint 1820 and the second joint can be provided where the sixth panel 1810 is formed from a separate piece of material which is subsequently joined to the fourth panel 1814 and the fifth panel 1815. Of course, forms where the sixth panel 1810 is integral with the fourth panel 1814 and the fifth panel 1815 are also envisaged. A third joint 1830 and a fourth joint 1840 can extend outwards from the second face 1812 and the third face 1813, respectively. It should be noted that the first joint 1820, the second joint, the third joint 1830, and the fourth joint 1840 can collectively comprise the ring joint discussed here. Thus, one, all, or any combination of these joints can exhibit the tensile strength of the ring joint as described here. As shown, the 1800 packaging may further include a fifth seam 1850 and a sixth seam 1860 which are arranged on the sixth panel 1811. The fifth seal 1850 and the sixth seal 1860 can extend into a seal fin 1880. It should be noted that the 1800 packaging and its associated seams can be assembled as described herein with regard to adhesives, barrier films, and / or combinations of barrier films and adhesives. However, the 1800 packaging is particularly well-suited for creating seams by coating an internal surface of the packaging material with a barrier film. In such configurations, the film can form a barrier that reduces the likelihood, or at least the amount, of water vapor passing through the packaging material to the absorbent articles within it. Packaging designs are also considered where the packaging comprises fewer than six panels. Packaging with a circular or semi-circular shape when viewed from a lower panel is considered. In addition, packaging with a triangular shape when viewed from the lower panel is considered. Regardless of the number of panels in the packaging described herein, the packaging includes one panel facing the consumer. Absorbent article configuration The packaging described herein may contain one or more absorbent items. The absorbent items may be placed in the packaging in an unfolded or folded configuration. The items may be folded laterally and / or longitudinally. The items may have one fold line and may be arranged within the packaging in a two-fold configuration. The items may have two fold lines and may be arranged within the packaging in a three-fold configuration. Figure 3A shows an example of a feminine hygiene napkin in an unfolded configuration. Figure 3B shows a side view of the feminine hygiene napkin from Figure 3A in a three-fold configuration. The feminine hygiene napkin shown in Figures 3A and 3B comprises a first fold line 3400 arranged between a first end region of the napkin 3100 and a central region of the napkin 3300, and a second fold line 3402 arranged between a second end region of the napkin 3200 and the central region 3300. Before being placed in the packaging, the second end region 3200 can be folded over and longitudinally inwards around the second fold line 3402 to overlap at least part of the central region 3300, as can be seen from a comparison of Figures 3A and 3B.The first end region 3100 can then be folded over and longitudinally inwards around the first fold line 3400 for . overlap at least part of the central region 3300 and part of the second end region 3200. In some examples a three-fold configuration may have the article folded approximately in three, around the two lateral fold lines spaced in the longitudinal direction. Figures 4A to 4D depict an absorbent article in the form of a baby diaper 4000 with front and back waistband edges 4100, 4200, in successive open / unfolded and folded configurations. For bulk packaging, each of a plurality of baby diapers such as that shown in [Fig. 4A] can, in a first possible step, have its longitudinal side portions folded over and laterally inward around longitudinal side edge fold lines 4300, as can be seen from a comparison of Figures 4A and 4B. Then, the baby diaper can, in a second step, be folded longitudinally around a side fold line 4400 that passes through the crotch area of ​​the baby diaper, as can be seen from a comparison of Figures 4B and 4C.For a two-fold configuration as shown in Figures 4C and 4D, the article can be folded lengthwise once, and in some examples can be folded approximately in half around the lateral fold line 4400. Regardless of whether the article is in a two-fold or three-fold configuration, the folded article, such as a folded feminine hygiene napkin 3000 and / or a folded baby diaper 4000, may have a single fold nose 30 defining at least one end edge of the folded article, fold nose corners 32, and left and right longitudinal peripheral edges 4500, 4600. It should be noted that in a three-fold example, a single fold nose may define each of the two end edges of the folded article. In some examples, as shown in Figures 4C and 4D, the fold nose 30 may be near the crotch area of ​​the article (the midline area of ​​the article adapted to be positioned between the wearer's legs while wearing).The folded article will have a folded width LP measured as the distance between the side edges, a folded height HP measured as the distance between the fold nose 30 and the end edges (in the case of a two-fold configuration) or between the two fold noses 30 (in the case of a three-fold configuration), and a side width (LL). The folded width (LP) forms the wide, flat face of the folded absorbent article, while the side width (LL) forms the narrow folded side of the absorbent article. A plurality of folded articles as shown in Figures 3B and 4C and 4D can be placed in a similar orientation within the inner compartment of a package of this description. Figures 5 and 6 show a plurality of absorbent articles arranged within a package of this description. Description. As shown in [Fig. 5] and [Fig. 6], the packaging 1000 defines an internal compartment 1002 where a plurality of absorbent articles 1004 are located. The plurality of absorbent articles 1004 can be arranged in a single horizontal row, as shown in [Fig. 5], or in one or more vertical stacks 1006, as shown in [Fig. 6]. When the articles are arranged in more than one vertical stack, as shown in [Fig. 6], all the articles can be oriented in the same direction. In another example, a first set of the plurality of folded articles can have their fold noses 30 oriented along one side of the stack, and a second set of the plurality of folded articles can be rotated 180 degrees to have their fold noses oriented along the opposite side of the stack. In some examples, the articles in the first set and the articles in the second set can appear in an alternating sequence in the stack. The folded absorbent articles can be arranged within the packaging described herein so that the folded width (FL) faces the first and second side panels. This configuration can be used when the number of absorbent articles within the packaging is relatively large, for example, more than about ten individual absorbent articles, because the narrower sides (LS) of the articles will form the front and back panels. For this reason, a relatively large number of absorbent articles can then be used to construct the front and back panels of the packaging. This configuration can be advantageous when the front and / or back panels form the panel facing the consumer. In such a configuration, when the absorbent articles are in a three-fold arrangement, the fold edges can be positioned close to the front and back panels of the packaging. The folded absorbent articles can be arranged within the packaging described herein so that the folded width (FL) faces the front and rear panels. This configuration can be used when the number of absorbent articles in the packaging is relatively small, for example, fewer than about ten individual absorbent articles, because the wider sides (FL) of the articles will form the front and rear panels. This configuration can be advantageous when the front and / or rear panels form the panel facing the consumer, and the number of absorbent articles in the packaging is less than about ten. In this configuration, when the absorbent articles are in a three-fold arrangement, the fold edges can be positioned near the first and second side panels of the packaging. Absorbent items can be compressed to reduce packaging size while still providing an adequate number of absorbent items per package. By packaging absorbent items Under compression, healthcare providers can easily handle and store the packaging, while also providing distribution savings for manufacturers due to the reduced packaging size. Despite the lack of stretch properties of conventional plastic packaging material, inventors have surprisingly discovered that the packaging materials described herein are capable of withstanding the rigors of handling and distribution, as mentioned herein, even with absorbent items compressed within the packaging and without the use of an intermediate receptacle. This is particularly unexpected given that the materials described herein may not exhibit the stretch properties of conventional plastic films currently in use. The packaging of the absorbent articles in this description may have a bag stack height of less than about 150 mm, less than about 110 mm, less than about 105 mm, less than about 100 mm, less than about 95 mm, less than about 90 mm, less than about 85 mm, less than about 80 mm, less than about 78 mm, less than about 76 mm, less than about 74 mm, less than about 72 mm, or less than about 70 mm, specifically citing all 0.1 mm increments within the specified ranges and all ranges formed within them, or as a result, according to the bag stack height test described herein.Alternatively, the packaging of the absorbent articles in this description may have a bag stack height ranging from about 70 mm to about 150 mm, from about 70 mm to about 110 mm, from about 70 mm to about 105 mm, from about 70 mm to about 100 mm, from about 70 mm to about 95 mm, from about 70 mm to about 90 mm, from about 70 mm to about 85 mm, from about 72 mm to about 80 mm, or from about 74 mm to about 78 mm, specifically citing all increments of 0.1 mm within the specified ranges and all ranges formed within them, or thereby, according to the bag stack height test procedure described herein. Opening elements The packagings described herein containing absorbent articles include features that facilitate opening without undesirable deformation or destruction of the packaging (opening features), so that the opened packaging can be used, after opening, as a receptacle for storing unused product. The opening features include one or more weakened regions. The inventors have discovered, surprisingly, that packagings described herein having a balance between the strength properties of the packaging materials and the strength properties of the weakened region can provide packaging flexible and elastic that can withstand the rigors of a manufacturing process while ensuring an opening element that is designed to facilitate opening of the packaging and minimize deformation of the packaging material along the path during opening. Weakened areas may have a tensile strength lower than that of unweakened areas of the packaging, allowing the packaging to open at the weakened points while the unweakened areas remain intact. However, the tensile strength of the weakened areas may be sufficient to withstand unintentional opening during packaging formation, shipping, retail display, and everyday use by a consumer. The inventors also discovered that weakened region formation can be more efficient and less bulky when the conditioning elements are formed from a single layer (a stratum) of conditioning material as opposed to multiple layers. As discussed here, the conditioning materials described herein can enable the formation of conditioning elements comprising a single layer of conditioning material while still exhibiting sufficient strength and elasticity. Arranging weakened regions within a single layer (a stratum) of conditioning material can require less energy and time compared to arranging weakened regions across multiple layers of material. Weakened areas may include folds arranged in the packaging material that are configured to make the weakened area less resistant to tearing or bursting than unfolded portions of the packaging material. Weakened areas may also, or rather, include perforations and / or cuts in the packaging material. Perforations and / or cuts may form a path or paths along a portion or portions of the packaging material. The path may be continuous.For this purpose, a "continuous" perforation or notch path is a singular path of successive, individual, partial or complete perforations created mechanically; a singular path of successive, individual, partial or complete perforations notched by laser; or a continuous singular path of mechanical and / or laser notches that is uninterrupted by any unperforated / unnotched portion of the packaging material. The packagings described herein may comprise a single path or may comprise multiple perforation and / or notch paths. The perforation and / or notch path(s) may form a generally straight line or may form a curvilinear shape. As shown in the non-limiting examples of Figures 7A to 7E, per- Individual perforations and / or notches defining a path 60 may have any configuration suitable for propagating a tear in the conditioning material along the path. When the path 60 of perforations and / or notches comprises a plurality of mechanically created individual perforations or cuts, or laser-notched individual perforations or cuts, it may be desirable for the path to have a cut-to-flat ratio of between approximately 0.7:1 and approximately 6:1, between approximately 0.8:1 and approximately 5:1, or between approximately 1:1 and approximately 4:1, specifically citing all values ​​within these ranges and all areas formed within or by them.For packaging materials of the type considered here, a cut-to-flat ratio within this range is thought to strike an appropriate balance between providing ease of opening the packaging and minimized deformation of the packaging material along the path during opening, and preventing unintentional bursting or premature opening of the packaging, and maintaining the structural integrity of the packaging during formation, shipping, handling, and other events prior to intentional opening by the consumer. For this purpose, the "cut-to-flat ratio" of a perforation and / or notch path is the ratio of the aggregate lengths of perforations or cuts extending along the direction of the path to the aggregate minimum distances of unperforated / unnotched portions of the packaging material between successive perforations. With reference to [Fig.8], for example, where part of a trajectory of successive rectangular perforations inclined in the diagonal direction is represented resting along the direction of trajectory STr, the cut-on-flat ratio is (L1 + L2 + L3) : (S1+S2+S3). . Individual perforations and / or notches may have any configuration that can form a weakened region. As shown in [Fig. 7A], individual perforations and / or notches 66 may be in the form of a straight line. The straight perforation and / or notch, as shown in [Fig. 7A], may generally be aligned parallel to the path 60 of perforations and / or notches. As shown in [Fig. 7B], individual perforations and / or notches 66 may be aligned such that each individual perforation and / or notch is arranged at an angle to the path 60 of perforations and / or notches. The angle may be between approximately 20° and approximately 80°. With reference to [Fig. 7E], individual perforations and / or notches 66 may include a first leg 61 and a second leg 63.The first leg 61 can generally be positioned parallel to the path 60 of perforations and / or notches. The second leg 63 can be positioned at an angle to the path 60 of perforations and / or notches. The angle can be between approximately 20° and approximately 80°. In another embodiment, the second leg 63 may be arranged generally parallel to the path 60 of perforations and / or notches, and the first leg 61 may be arranged at an angle to the path 60 of perforations and / or notches, wherein the angle may be between approximately 20° and approximately 80°. With reference to [Fig. 7C], the individual perforations and / or notches 66 may comprise three legs, in which at least one of the legs may be arranged at an angle to the path 60 of perforations and / or notches, and wherein the angle may be between approximately 20° and approximately 80°.It is thought that weakened areas including perforations and / or notches comprising at least one tab arranged at an angle to the path of perforations and / or notches may exhibit lower tensile strength, but be more resistant to tearing and accidental opening during manufacturing processes. With reference to Figures 9A to 9E, when the packaging in this description includes weakened areas comprising multiple perforation and / or notch paths 60, the paths may be separated by aligned flat areas 62. The aligned flat areas 62 may be longer than the flat areas of the paths they separate when measured in line with adjacent paths. The length of the aligned flat area may be large enough to distinguish it from the flat areas of the adjacent perforation and / or notch paths, but may not be so large as to disrupt the opening of the two adjacent paths when force is applied by a user. The aligned flat area may coincide with a fold or crease in the packaging material, such as at a corner between two panels.The aligned flat area can help prevent the unintentional opening of opening elements in parts of the packaging that may be pre-weakened or that may experience some increased stress due to the arrangement of the weakened area on a fold and / or crease in the packaging. The aligned flat areas can have a length from approximately 1.5 mm to approximately 25 mm, from approximately 2 mm to approximately 20 mm, or from approximately 2 mm to approximately 10 mm, specifically citing all 0.1 mm increments within the specified ranges and all areas formed within or by them. The perforation and / or notch path may include a single, uninterrupted line of laser notch that does not fully penetrate the packaging material but is designed to promote clean tear propagation along the path. The uninterrupted line of laser notch may be arranged on the packaging material coinciding with a fold line or may be arranged on a flat portion of the packaging material. The arrangement a single, uninterrupted line of laser notch coinciding with a fold line, can improve the ability of an already weakened region to tear or burst along a designated path when sufficient force is applied, while the rest of the conditioning retains its shape and integrity. Referring again to Figures 7A to 7E, the perforation pattern in the perforation path 60 may depend on the location on the packaging where the weakened area is situated. Perforation patterns with a higher cut-to-flat ratio may be desirable in a weakened area where a perforation path crosses a gusset structure, because a gusset structure includes more than one layer of packaging material and may be more difficult to tear.Furthermore, when a plurality of absorbent articles are packaged within the packaging described herein under compression, the perforation configuration may be arranged such that at least part of the cuts are arranged diagonally to, or perpendicular to, the direction of tension in the packaging material created by the compression of the absorbent articles, as shown in Figures 9B, 9C, and 9E. In such a configuration, the perforations are thought to be less likely to expand and / or open before intentional opening by the consumer. With reference to Figures 10 and 11, in order to reduce the likelihood that a consumer opening the packaging will tear the packaging material beyond the endpoints 64 and 65 of the perforation and / or notch path 60, and deform the packaging material and / or reduce the usefulness of the packaging for storing and / or protecting unused items, it may be desirable to include a stress-dispersing element 69 near one or both of the points endpoints 64, 65. As shown in Figures 10 and 11, the tear stress dispersion element 69 is a semi-circular perforation or cut extending transversely in the direction of the path 60, which serves to disperse tear stresses concentrated at the endpoint and to impede tear propagation in a way that can be felt by the consumer. It can be observed that the tear stress dispersion element 69 can have other forms, including other shapes of cuts and / or perforations through the packaging material, extending transversely in the direction of the path 60, reinforcing strips, added tapes, and the like. Figure 12A is a perspective view of packaging of the present description in a closed configuration, and Figure 12B shows packaging of Figure 12A in a partially open configuration. With reference to Figures 12A and 12B, packaging 1 of the present description may include an upper panel 11 comprising closure gussets 11b, a seam of closure 1a, and a closure seam wing 11c. A weakened region 700 may be disposed on at least part of the closure seam wing 11c between the closure seam | la and an inner compartment 702 comprising one or more absorbent articles. The weakened region 700 may pass through at least part of the closure gussets 11b. The weakened region 700 may include a series of perforations and / or notches 704. The series of perforations and / or notches 704 may form a path generally parallel to the closure seam la. The path of perforations and / or notches may have a relatively high cut-to-flat ratio.A relatively high cut-to-flat ratio may be preferable when the perforation and / or notch path passes through at least part of the closure gussets, because the closure gusset portion comprises four layers of packaging material, and a higher cut-to-flat ratio can reduce the amount of force required to form an opening in the packaging. For example, the cut-to-flat ratio may be between approximately 0.7:1 and approximately 6:1, or between approximately 1:1 and approximately 6:1, or between approximately 2:1 and approximately 6:1, specifically citing all values ​​within these ranges and all areas formed within them. The weakened region can be designed to form an opening along the path of perforations and / or notches. The weakened region 700, comprising the series of perforations and / or notches 704, can be configured so that the closure seam wing 11c can be completely removed from the rest of the packaging 1. In such a configuration, removing the closure seam wing 11c can create a large opening—defined by the front panels 14, rear panels 15, and the first and second side panels 12, 13—to allow easy access to the absorbent item(s) arranged in the inner compartment 702. An additional benefit of a large opening created by the complete removal of the closure seam wing is that the absorbent items can be configured in any way within the inner compartment and can still be easily removed. Figure 13A is a perspective view of a packaging of the present description in a closed configuration, and Figure 13B shows the packaging of Figure 13A in a partially open configuration. With reference to Figures 13A and 13B, a packaging 1 of the present description may include a weakened region 700 disposed on at least part of an upper edge region 706 of the packaging | between at least one of: the upper panel 11 and the front panel 14, the upper panel 11 and the rear panel 15, the upper panel 11 and the first side panel 12, and the upper panel 11 and the second side panel 13. When the upper panel 11 includes closure gussets 11b, the weakened region 700 may to be positioned below the 1 lb closure gussets. A relatively low cut-to-flat ratio may be preferable when the perforation and / or notch path does not pass through any part of the closure gussets, because the conditioning area outside the closure gussets comprises only a single layer of conditioning material. For example, the cut-to-flat ratio may be between approximately 0.7:1 and approximately 6:1, or between approximately 1:1 and approximately 5:1, or between approximately 2:1 and approximately 4:1, specifically citing all values ​​within these ranges and all areas formed within or by them. A package of this description may include a weakened region, in which the weakened region is located on a portion of the upper edge of the package only between the top panel and the front panel or only between the top panel and the back panel. Such a weakened region configuration may be advantageous when items are arranged within the inner compartment of the package in a three-fold configuration and positioned so that the fold tips are located near the first and second side panels of the package. In such a configuration, the weakened region may form an opening slit approximately the same size as the item, allowing only one item at a time to pass through the opening, thus keeping the remaining items securely and neatly within the package. A package of this description may include a weakened region which is disposed on a portion of the upper edge region of the package only between the upper panel and two contiguous panels, such as the front panel and a side panel, or the rear panel and a side panel. A package of this description may include a weakened area located on a portion of the upper edge of the package, specifically between the top panel and three adjacent panels, such as the front panel and both side panels, the back panel and both side panels, or one of the side panels and either of the front and back panels. In such a configuration, the weakened area may form an opening that leaves one side of the top panel attached to the rest of the package, thus forming a hinge. For this reason, the top panel can be removed from the top of the inner compartment to allow access to all the items within the package; however, the top panel will remain attached to the package and thus readily available for replacement above the items. A package as described herein may include a weakened area located on a portion of the upper edge region of the package between the top panel and the front, rear, and either of the side panels. In a In this configuration, the top panel can be completely removable. This configuration can create a large opening to allow easy access to the interior compartment and the items inside. With reference to Figures 14A and 14B, a package 1 of this description may include a weakened region 700 disposed on at least a portion of the top panel 11, at least a portion of the front panel 14, at least a portion of the back panel 15, and at least a portion of one of the first or second side panels 12, 13. The weakened region may surround a closure gusset 11b. The weakened region may form an opening when appropriate force is applied by a consumer, allowing the closure gusset 11b to be removed. The removal of the closure gusset may create an entry point into the inner compartment of the package, approximately the same width as the sides of the package. Such an entry point may be provided for the easy removal of items that are arranged side-to-side within the package.The weakened region may include a path of perforations and / or notches with a cut-to-flat ratio between approximately 0.7:1 and approximately 6:1, or between approximately 1:1 and approximately 5:1, or between approximately 2:1 and approximately 4:1, specifically citing all values ​​within these ranges and all ranges formed within or thereof. Figure 15A is a perspective view of a packaging 1 of the present description comprising a weakened region 700 disposed on at least a portion of at least three of the packaging faces. Figure 15B shows the packaging of Figure 15A in an open configuration. With reference to Figure 15A, the weakened region may include a series of perforations and / or notches 704 disposed on a portion of each of the at least three faces. The weakened region 700 may include a single path of perforations and / or notches 704 arranged along each of the panels, or, as discussed with regard to Figures 9A to 9E, the weakened region may include several paths of perforations and / or notches 704 separated by aligned flat areas 62. The aligned flat areas may be arranged at transition areas between the panels of the packaging, such as at the corners of the packaging.The weakened region 700 can be disposed on at least three of the front 14, rear 15, first side 12, and second side 13 panels, such that the weakened region 700 defines a base 1502 of the packaging and a cap structure 1504. With reference now to [Fig. 15B], it is thought that a cap structure 1504 having three sides, each formed from a portion of one of the front 14, rear 15, first side 12, and second side 13 panels, and a top formed from a portion of the upper panel 11, can provide an effective, easy-to-use cover for supplying unused absorbent articles disposed within the packaging, and can help to protect against. The entry of airborne contaminants into the packaging. The cap structure 1504 is formed when the consumer tears the packaging material along the weakened region 700. When the weakened region is located on only three sides, part of the cap structure can be partially detached from the base, since at least one side can remain intact and attached to the base. After opening, the cap structure 1504 can be resealed by returning it to a position similar to its position relative to the rest of the packaging before opening. Such a configuration can be advantageous when absorbent items are configured in a two-fold configuration, and in which the fold nose is located near the top side of the packaging.In such a configuration, it is thought that the folding nose of the item provides a convenient single part by which to grasp the item to remove it from the packaging. As shown in Figures 15A and 15B, the weakened region 700 may include one or more perforation and / or notch paths 704 arranged on one or both of the first or second side panels 12, 13, as well as on portions of either of the front and rear panels 14, 15. This configuration (here referred to as the "long-short-long" or "LCL" path) forms an opening along the entire length of one short side (either the first or the second) of the package. Such a configuration can be particularly useful when absorbent articles are stacked within the package from side panel to side panel. In such a case, the full width of the article can be exposed when the package is opened, and the article can be easily removed. The perforation and / or notch path(s) may not extend through the entire width of the front and / or rear panels.For example, the path(s) of perforations and / or notches may cross approximately 25 percent, approximately 33 percent, approximately 45 percent, approximately 50 percent, approximately 60 percent, or approximately 75 percent of the width of the front and rear panels. With further reference to Figures 15A and 15B, where the perforation and / or notch path(s) 704 do not cross the entire width of the front and / or rear panels, it may be beneficial to have a stress dispersion element 69 positioned near the endpoint of the perforation and / or notch path(s) 704. As discussed, the stress dispersion element can serve to disperse tearing stresses concentrated at the endpoint, and can help to reduce or prevent tearing of the conditioning material beyond the endpoint of the perforation and / or notch path(s).In another example, the perforation and / or notch trajectory(ies) cross the entire width of the front and rear panels. In another form, shown in [Fig. 16], the weakened region 700 may include a trajectory or trajectories of perforations and / or notches 704 arranged on one of the front or rear panels 14, 15, as well as on portions of either of the first and second side panels 12, 13. This configuration (here referred to as a "short-long-short" or "CLC" path) is designed to create an opening along the entire length of one long side (either the front or the rear) of the package. Such a configuration can be particularly useful when items are stacked within the package from the front panel to the rear panel. In such a case, the full width of the item can be exposed when the package is opened, and the item can be easily removed. The perforation and / or notching path(s) extend across the entire width of the side panels. Alternatively, the perforation and / or notching path(s) may not extend across the entire width of the side panels.For example, the perforation and / or notch path(s) may traverse approximately 25 percent, 33 percent, 45 percent, 50 percent, 60 percent, or 75 percent of the width of the side panels. The weakened region 700 may include a stress dispersion element disposed near the endpoints of the perforation and / or notch path(s), as discussed in relation to Figure 15. In one configuration, the weakened area can be arranged on each of the front, rear, first side, and second side panels. The weakened area may include one or more perforation and / or notch paths that pass through each of the panels. In such a configuration, the cap structure can be completely removable from the base. This configuration can be advantageous when the packaging material has limited flexibility and is prone to tearing. With reference now to Figures 15A, 15B and 16, the weakened region 700 can be arranged on at least three sides of the conditioning unit 1 such that the base 1502 has a base height (HB), and the cap structure 1504 has a cap height (HC). The base height can range from about 60 percent to about 90 percent, from about 65 percent to about 85 percent, or from about 70 percent to about 85 percent of the total height of the conditioning unit, specifically citing all values ​​within these ranges and all ranges formed within or by them. It is thought that consumers may prefer that the cap structure have at least a minimal amount of material to grasp and remove from the unused portion of the absorbent material in the package. This minimal amount of material can be placed around a portion of the stack of absorbent material in the package and remain in place until it is removed again by a user. Packages described herein may therefore have a cap height (CH) of at least approximately 15 mm, at least approximately 20 mm, or at least approximately 25 mm. The packaging described herein may include more than one weakened region. Each weakened region may include one or more perforation and / or notch paths. The multiple perforation and / or notch paths may not intersect. The packaging described herein includes more than one weakened region within the first 50% of the packaging height. The packaging described herein may include a graphic cue and / or an identifying dye to signal to a user the presence of a weakened area. In one form, the weakened area may include an identifying dye. The identifying color may be a different color from a color displayed on a consumer-facing panel of the packaging. The packaging may also, or instead, include a graphic representation, for example, a graphic of a pair of scissors, placed adjacent to the weakened area. The inventors have found that placing a graphic cue and / or an identifying dye in the weakened area of ​​the packaging described herein can increase consumer recognition and satisfaction with the weakened area, which is designed to function as an opening element. Without distinction of the weakened region configuration of the conditionings of this description, the conditionings may have a weakened region tensile strength (WRTS) of not less than 1.18 kN / m, or between about 1.18 kKN / m and about 8.00 kN / m, between about 1.27 kN / m and about 6.50 kN / m, between about 1.35 kN / m and about 5.00 kKN / m, between about 1.49 kN / m and about 4.72 kN / m, between about 1.49 kN / m and about 3.35 kN / m, or between about 1.6 kN / m and about 3.00 kN / m, specifically citing all values ​​within these ranges and all ranges formed within them, or thereby, according to the tensile strength test procedure described herein. It is believed that packaging including a weakened region with an RTRA within the above ranges may be sufficient to withstand unintentional breakage during packaging formation, packaging filling, shipping, and store display.. The inventors discovered that packaging with a balance between the strength properties of the packaging material in an unweakened region (tensile strength) and the strength properties of the packaging material in the weakened region (RTRA) can provide flexible and elastic packaging that can withstand the rigors of a manufacturing process while also providing an opening element designed to facilitate opening the packaging. This balance can be calculated by taking the ratio of the re- The weakened region tensile strength (RTRA) of a package relative to the tensile strength of a portion of the package without a weakened region (according to the tensile strength test procedure), referred to herein as the "weakened region performance factor" (PRA factor). Packages in this description may have a PRA factor ranging from approximately 0.14:1 to approximately 0.98:1, approximately 0.15:1 to approximately 0.98:1, approximately 0.16:1 to approximately 0.94:1, approximately 0.18:1 to approximately 0.94:1, approximately 0.19:1 to approximately 0.94:1, approximately 0.2:1 to approximately 0.94:1, or approximately 0.23:1 to approximately 0.6:1, specifically citing all values ​​within these ranges and all ranges formed within or by them. Table 2 presents weakened region tensile strength (TRTS) data from various packaging material samples. TRTS and PRA factor data for weakened region configurations, including perforation paths with different cut-to-flat ratios and perforation shapes, are shown for each packaging material. All weakened regions in the samples shown in Table 2, except for the "Slanted Perf" variable, include straight perforations with a flat area of ​​1 mm. The "Slanted Perf" variable includes profiled perforations as shown in [Fig. 7E], with a flat area of ​​approximately 2.5 mm. Sample 5 is a specialty calendered kraft paper packaging material made entirely of virgin fibers with a basis weight of 70 g / m², available from Mondi'M under the Advantage Smooth White Strong brand. Various weakened region configurations, including perforation paths arranged in the ST direction of the packaging material, are shown. Sample 6 is a paper conditioning material produced from pure white kraft paper pulp and made entirely of virgin fibers with a surface mass of 70 g / m², available from BillerudKorsnäsTM. Various weakened region configurations including perforation paths arranged in the ST direction of the conditioning material are presented. Sample 7 is a paper conditioning material produced from pure white kraft pulp and consisting entirely of virgin fibers with a basis weight of 80 g / m², available from BillerudKorsnäsTM under the brand name Axello Tough White. Various weakened region configurations, including perforation paths arranged in the ST direction of the conditioning material, are shown.

The data suggest a trend whereby lower cut-to-flat ratio configurations exhibit higher tensile strength per Comparison with higher cut-to-flat ratio configurations. However, weakened regions with angled perforations do not follow this trend. Weakened regions with angled perforations exhibit the lowest RTRA. Weakened region performance factor (PRA Factor) data follow a similar trend to RTRA data, with lower cut-to-flat ratio configurations exhibiting higher PRA Factor ratings. Table 3 presents the tear strength data for samples 5 and 7, as described previously. Absolute tear strength is the force required to tear a single flat area of ​​perforations within the first 5 flat areas of perforations in a weakened region, as measured by the tear strength test procedure described here. Relative tear strength is the average force required to tear 1 mm of flat area across the first 5 flat areas of perforations in a weakened region, as measured by the tear strength test procedure described here. The data can be useful in determining perforation configurations and patterns that may be relatively easy for a consumer to open.

The relative tear strength was slightly greater for sample 5 compared to sample 7. This is consistent with the RTRA data presented in Table 2, showing that the various The weakened region configurations in Sample 5 have slightly higher RTRAs than the same configurations in Sample 7. Without being bound by any theory, it is thought that the higher RTRA and relative tear strength of Sample 5, compared to the same configurations in Sample 7, may be due to the conditioning material in Sample 5 having a slightly higher tensile strength in the SM. The weakened region with angled perforations in Sample 7 failed to open five consecutive flat areas in two replicates. During the test in these two replicates, the tear line deviated from the perforation path in the unperforated conditioning material. Without distinction of the configuration of the weakened region of the conditionings of this description, the weakened region may have an absolute tear strength of between about 0.63 N and about 1.56 N per single flat area of ​​perforations, between about 0.73 N and about 1.46 N per single flat area of ​​perforations, or between about 0.8 N and about 1.3 N per single flat area of ​​perforations, according to the tear tensile test procedure described herein. The conditioneds in this description may include a weakened region having a relative tear strength of between about 0.8 N / mm and about 1.3 N / mm, between about 0.9 N / mm and 1.2 N / mm, or between about 0.95 N / mm and about 1.15 N / mm, depending on the tear tensile test procedure described herein. The inventors discovered, without limiting themselves to any particular theory, that process reliability on commercial-scale, high-speed packaging equipment and acceptable opening capability of the weakened region can be achieved simultaneously by appropriately balancing the weakened region tensile strength (TRTS) and the weakened region tear strength. Proper balancing of these parameters can provide packaging that can withstand the rigors of a manufacturing process while also ensuring an opening element designed for easy opening by a consumer with minimal damage to the unweakened region of the packaging. This balance can be represented by a tear performance factor (TPF).The PD factor is defined as the ratio of the weakened region tensile strength (RTRA) of the packaging, according to the tensile strength test procedure described herein, to the absolute tear strength of the weakened region of the packaging, according to the tear-tensile test procedure described herein. The packagings described herein may have a PD factor ranging from approximately 0.8 to approximately 5, from approximately 0.9 to approximately 4.5, or from approximately 1 to approximately 4, specifically citing all values ​​within these ranges. and of all the areas formed within them or as a result. It is thought that a package having a PD factor within the above ranges can exhibit sufficient strength to withstand manufacturing processes while being easily workable around the weakened area with minimal destruction to the unweakened area of ​​the package. Testing methods All measurements are performed in a laboratory maintained at 23°C +2°C and 50% +2% relative humidity and test samples are conditioned in this environment for at least 2 hours prior to testing, unless otherwise specified. Tensile strength test method The tensile strength test procedure is performed according to ASTM D828-16 "Standard Test Method for Tensile Properties of Paper and Paperboard Using Constant-Rate-of-Elongation Apparatus" with the following specifications and / or modifications: Two sets of test specimens are cut from packaging material containing a weakened region. The first set of test specimens contains the weakened region, such that the weakened region is oriented across the entire width of the test specimen and is centered along and perpendicular to the length of the test specimen. The second set of test specimens is cut from the same packaging material and is oriented in the same direction as the first set but does not include a weakened region.The specimen length is approximately 101.6 mm (4 inches) to allow sufficient specimen to be gripped in the instrument's jaws with a jaw spacing of 50.8 mm (8 inches). The jaw separation speed during the test is 300 mm / min. When placing the test specimens containing the weakened region in the jaws for testing, the trajectory of the weakened region must be centered between the jaws and perpendicular to the tensile axis of the tensile tester. The average tensile strength of the first set of specimens containing the weakened region is reported as the weakened region tensile strength (RTRA) to the nearest 0.01 kN / m. The average tensile strength of the second set of specimens without the weakened region is reported as the conditioning tensile strength (SM or CT) to the nearest 0.01 kN / m. Weakened Region Performance Factor (WRP) - The weakened region performance factor is calculated by taking the ratio of the weakened region tensile strength (WRTS) of a condition to the tensile strength of the condition measured in the same direction (SM or ST). The factor is calculated according to PRA factor = PÉsERmE at the pren de rés nf weakened k; Conditioning tensile strength (SH Tear tensile strength test method The tensile tear test procedure is performed according to ASTM D2261-13 "Tearing Strength of Fabrics by the Tongue (Single Rip) Procedure" The Constant-Rate-of-Extension Tensile Testing Machine (CET) has been adapted to test conditioning materials comprising natural materials and a weakened region, with the following specifications and / or modifications: Test specimens are cut from conditioning materials containing a weakened region such that the path of the weakened region is oriented along the center of the specimen's width. The specimen width is 50.4 mm (2 inches), with 25.4 mm (1 inch) on each side of the line of weakened regions. The preliminary 75 mm (3-inch) cut made along the center of the width should not partially cut any flat area within the weakened region, so that only the entire flat areas are torn during the test.A total of five repeated test specimens are prepared. The clamp distance is set to 50.4 mm (2 inches) at the start of the test, and a test speed of 300 mm / min is used. The preconditioning, conditioning, and testing of dry test specimens is performed as specified in ASTM D685-17, "Standard Practice of Conditioning Paper and Paper Products for Testing." Calculation option 1, the average of the five highest peaks, is used to measure the average tear strength (peak force) of each of the first five flat areas torn during the test and recorded to the nearest 0.01 N. This procedure is repeated for all five test specimens, and the arithmetic mean of the five recorded values ​​is calculated and reported as the absolute tear strength value to the nearest 0.01 N.The absolute tear strength value is divided by the average width of all flat areas that were torn and the peak forces measured during testing, and is reported as the relative tear strength value to the nearest 0.01 N / mm. Tear Performance Factor (TPF) — The tear performance factor is calculated by taking the ratio of the weakened region tensile strength (TRTS) of the packaging, according to the tensile strength test procedure described here, to the absolute tear tensile strength of the weakened region of the packaging, according to the tear tensile test procedure described here. The factor is calculated using the following equation and indicated to the nearest 0.01 unit: PD factor = tensile strength of weakened region (4) 5 absolute tear tensile strength (N) Estsssane N 1 snees THÉ a ane A VA AAA An6 AATAUTÉ AA At tanne AM AAA Stretch to break - The stretch to break is calculated by dividing the mean elongation at break (mm) by the initial test length (test span) of 50.8 mm, then multiplying by 100. Calculate the stretch to break for the repetitions in the SM and then the repetitions in the ST and report respectively as stretch to break in the SM and stretch to break in the ST to the nearest percentage. Tensile energy absorption (TEA) - Tensile energy absorption (TEA) is calculated using the following equation: AET = (1000”Area under curve, mJ) / {test sample width, initial test length} when the test sample width is 25.4 mm and the initial test length (test range) is 50.8 mm. Calculate the AET for the replicates in the SM and then the replicates in the ST, and report the results respectively as AET in the SM and AET in the ST to the nearest J / m. Tensile Energy Absorption Index (TEA) - The tensile energy absorption index (TEA) is calculated using the following equation: AET index = (AET) / Acetic surface mass where AET is in units of J / m° and the surface mass is in units of g / m?, Calculate the AET index for the repetitions in the SM, then the repetitions in the ST and indicate respectively as AET index in the SM and AET index in the ST to the nearest J / g. Burst resistance test procedure Burst strength is the maximum uniformly distributed pressure that a test sample can withstand. Burst strength is measured according to the ISO 2758 pharmacopoeia procedure using a test apparatus as described in the procedure. A suitable instrument is the 13-60 Burst Tester for Paper and Metal Foil, available from Testing Machines, Inc. (New Castle, DE), or equivalent. The instrument is calibrated and used according to the manufacturer's instructions. Measurements are performed on test samples taken from rolls or sheets of the raw material, or from test specimens obtained from a finished package. When excising a test sample from a finished package, care must be taken to avoid any contamination or deformation of the test sample during the process. The test sample must be larger than the clamps used to hold it in the instrument. The test sample should be taken from an area free of folds, creases, or seams. Measure burst resistance (using sufficient clamping pressure to prevent slippage during the test, and a pumping speed of 95+ 15 mL / min) for a total of 10 repeated test samples. For lateral samples, the side of the test sample intended to face the inside of the packaging faces the pressure when placed in the clamps, and 10 repetitions are tested in this orientation. For balanced (non-lateral) samples, 5 repetitions are tested with the inside of the packaging facing the pressure and 5 repetitions are tested with the outside of the packaging facing the pressure, and the average of all results is calculated. Record the pressure at which each test sample bursts to ±0.001 kPa.If the burst pressure is less than 70 kPa, several layers of the test material must be used. To obtain the burst strength, divide the burst pressure by the number of layers tested. Calculate the arithmetic mean burst pressure for all repetitions and report as burst strength to plus or minus 0.001 kPa. Size testing method The thickness, or thickness, of a single-layer test sample is measured under a static load using a micrometer, in accordance with the procedure of Pharmacopoeia ISO 534, with modifications noted here. Size is measured with a micrometer equipped with a pressure foot capable of exerting a constant pressure of 70 kPa ± 0.05 kPa on the test specimen. The micrometer is a deadweight type instrument with measurements accurate to 0.1 micron. A suitable instrument is the TMI Digital Micrometer Model 49-56, available from Testing Machines Inc., New Castle, DE, or equivalent. The pressure foot is a circular, movable face with a flat base and a diameter smaller than the test specimen, capable of exerting the required pressure. A suitable pressure foot has a diameter of 16.0 mm. The test specimen is supported by a horizontal, flat reference platform that is larger than and parallel to the surface of the pressure foot. The system is calibrated and used according to the manufacturer's instructions. Measurements are performed on single-layer test samples taken from rolls or sheets of the raw material, or from finished packaging. When excising the test sample from finished packaging, care must be taken to avoid any contamination or deformation of the sample during the process. The excised sample must be free of residual adhesive and taken from an area of ​​the packaging that is free of any seams or folds. Ideally, the test sample is 200 mm in diameter and should be larger than the pressure foot. To measure size, first zero the micrometer on the flat, horizontal reference platform. Place the test sample on the platform with Position the test spot centered under the pressure foot. Lower the pressure foot moderately at a rate of 3.0 mm per second until full pressure is applied to the test sample. Wait 5 seconds, then record the size of the test sample to ±0.1 micron. Repeat this procedure for a total of ten repeated test samples. Calculate the arithmetic mean for all size measurements and report the value as size to ±0.1 micron. Surface mass test method The surface mass of a test sample is the mass (in grams) per unit area (in square meters) of a single layer of material and is measured in accordance with the ISO 536 pharmacopoeia procedure. The mass of the test sample is cut to a known area, and the mass of the sample is determined using an analytical balance accurate to 0.0001 gram. Measurements are performed on test samples taken from rolls or sheets of the raw material, or from finished packaging. When excising the test sample from finished packaging, care must be taken to avoid any contamination or deformation of the sample during the process. The excised sample must be free of residual adhesive and taken from an area of ​​the packaging that is free of any seams or folds. The test sample should be as large as possible to account for any inherent variability in the material. Measure the dimensions of the single-layer test sample using a calibrated metal ruler made of NIST-traceable steel, or equivalent. Calculate the area of ​​the test sample and record to ±0.0001 square meters. Use an analytical balance to determine the mass of the test sample and record to ±0.0001 grams. Calculate the surface density by dividing the mass (in grams) by the area (in square meters) and record to ±0.01 grams per square meter (g / m²). Repeat this process for a total of ten repeated test samples. Calculate the arithmetic mean for the surface density and report to ±0.01 grams per square meter. bag pile height test The stack height in a bag of absorbent material packaging is determined as follows: Equipment A micrometer with a rigid, flat, horizontal sliding plate is used. The micrometer is configured so that the horizontal sliding plate moves freely in a vertical direction, with the horizontal sliding plate always held in a horizontal orientation directly above a plate of The horizontal sliding plate has a flat, rigid base. The micrometer includes a suitable device for measuring the gap between the horizontal sliding plate and the horizontal base plate to +0.5 mm. The horizontal sliding plate and the horizontal base plate are larger than the surface area of ​​the absorbent material packaging that comes into contact with each plate; that is, each plate extends beyond the contact surface of the absorbent material packaging in all directions. The horizontal sliding plate exerts a downward force of 850 ± 1 gram-force (8.34 N) on the absorbent material packaging. This can be achieved by placing a suitable weight on the center of the upper surface of the horizontal sliding plate, without it being in contact with the packaging, so that the total mass of the sliding plate plus the added weight is 850 ± 1 gram. Testing procedure Absorbent product packaging is balanced at 23 +2 °C and 50 +5% relative humidity before measurement. The horizontal sliding plate is raised, and an absorbent material package is placed in the center beneath the horizontal sliding plate so that the absorbent material in the package is horizontally oriented (see [Fig. 6]). Any handles or other packaging features on the packaging surfaces that would come into contact with either plate are folded flat against the packaging surface to minimize their impact on the measurement. The horizontal sliding plate is lowered slowly until it contacts the top surface of the package, and then released. The gap between the horizontal plates is measured within 0.5 mm ten seconds after the horizontal sliding plate is released.Five identical packs (packs of the same size and the same number of absorbent items) are measured and the arithmetic mean is reported as the pack width. The "Stack Height in Bag" = (pack width / number of absorbent items per stack) x 10 is calculated and reported within + 0.5 mm. Gloss measurement test method Gloss measurements are performed on test samples taken from a finished package. When a consumer-facing panel of a package can be identified, test samples are taken from that panel. When excising the test sample from a finished package, care must be taken to avoid any contamination or deformation of the sample during the process. The excised sample must be free of residual adhesive and taken from an area of ​​the package that is free of any seams or folds. The test sample should be as large as possible. so that any inherent variability in the material is taken into account. Gloss is measured using a glossmeter, such as the 480 Glossmeter, available from Elcometer®, Warren, Michigan, USA. To determine the most appropriate measurement angle, take an initial measurement at a fixed angle of incidence of 60°. If the result is between 10 GU and 70 GU, the 60° angle of incidence is appropriate. If the result is less than 10 GU, the test sample should be measured again using an 85° angle of incidence. If the result is greater than 70 GU, the test sample should be measured again using a 20° angle of incidence. Measure three different areas of the same package and calculate the arithmetic mean. The arithmetic mean is reported as the gloss to the nearest 1 GU, along with the corresponding angle of incidence. The dimensions and values ​​described here should not be understood as being strictly limited to the exact numerical values ​​cited. Instead, and unless otherwise indicated, each of these dimensions corresponds both to the stated value and to an equivalent functional range around that value. For example, a dimension described as "40 mm" means "approximately 40 mm".
