Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to absorbent article packages, and more particularly, to absorbent article packages having natural fibers and opening mechanisms. [Background technology]

[0002] Consumer demand for products made at least in part from renewable resources has increased significantly over the past decade, driving the innovation of new and improved consumer goods and packaging materials. Thus, there is an increasing focus on products and packaging materials that contain renewable resources. For example, there is a strong desire in the market for consumer products that contain natural and biological source materials, recyclable materials, recycled materials, and / or biodegradable materials.

[0003] Non-fragile, compressible consumer products, such as disposable absorbent articles (e.g., diapers and training pants, disposable adult incontinence pants, and feminine hygiene pads), are often packaged and sold at retail in soft packages made of plastic polymer films. Given its ability to bend and stretch, plastic is preferred as the primary package for consumer goods because it can withstand the rigors of the packaging process. In addition, because plastic can bend and stretch without tearing when force is applied, opening mechanisms disposed within plastic packages tend to form clean openings while maintaining the integrity of the rest of the package. However, plastic packages tend not to hold their shape and may collapse upon removal of the article. Summary of the Invention [Problem to be solved by the invention]

[0004] Packages that contain renewable resources such as natural fibers (e.g., carton board, corrugated board, and paper) may be prone to creasing, cracking, and tearing during the packaging process and under opening strain. Therefore, packaging materials that contain renewable resources such as natural fibers for absorbent articles should be improved. [Means for solving the problem]

[0005] The present disclosure solves one or more of the problems discussed above by providing a package of one or more absorbent articles that includes a packaging material made at least in part from renewable resources and that includes an opening mechanism. The packaging material that includes the opening mechanism can withstand the rigors of the packaging process, shipping, and handling on the shelf and in the consumer's home. The opening mechanism can enable the package made at least in part from renewable resources to maintain its shape after opening and partial dispensing.

[0006] The present disclosure provides, in part, a package of one or more absorbent articles comprising a packaging material including natural fibers. The packaging material forms a front panel, a rear panel opposite the front panel, a first side panel, a second side panel opposite the first side panel, a top panel, and a bottom panel opposite the top panel, the panels defining an interior compartment. The one or more absorbent articles are disposed within the interior compartment. The packaging material has a basis weight of about 50 gsm to about 120 gsm, preferably about 55 gsm to about 115 gsm, and more preferably about 60 gsm to about 110 gsm, according to a basis weight test method described herein. The package includes a weakened area. The package is sealed such that the one or more absorbent articles are enclosed within the interior compartment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] As used herein, the term "absorbent article" refers to a device that absorbs and contains bodily exudates, and more specifically, to a device that is placed against or in close proximity to the body of a wearer to absorb and contain various bodily exudates. Absorbent articles of the present disclosure include, but are not limited to, diapers, adult incontinence briefs, training pants, diaper holders, menstrual pads, incontinence pads, liners, absorbent inserts, panty liners, tampons, and the like.

[0011] As used herein, the term "machine direction" or "MD" refers to the path that material, such as packaging material, follows through a manufacturing process.

[0012] As used herein, the term "cross-machine direction" or "CD" refers to the path within the plane of the material that is perpendicular to the machine direction.

[0013] As used herein, the term "natural fibers" refers to fibers including cellulosic fibers, bamboo fibers, and the like. Natural fibers also refer to non-wood fibers such as cotton, abaca, kenaf, sabai grass, flax, esparto grass, straw, jute, hemp, bagasse, milkweed floss fibers, and pineapple leaf fibers, as well as wood fibers such as wood or pulp fibers obtained from deciduous and coniferous trees, including softwood fibers such as northern and southern coniferous kraft fibers, and hardwood fibers such as eucalyptus, maple, birch, and aspen. Pulp fibers may be prepared in high-yield or low-yield form and may be pulped by any known method, including kraft, sulfite, high-yield pulping methods, and other known pulping methods. The natural fibers of the present disclosure may be recycled natural fibers, virgin natural fibers, or mixtures thereof. Additionally, for good mechanical properties in natural fibers, it may be desirable for the natural fibers to be relatively undamaged and primarily unrefined or only lightly refined. The fibers may have a Canadian Standard Freeness of at least 200, more specifically, at least 300, even more specifically, at least 400, and most specifically, at least 500.

[0014] As used herein, the term "cellulosic fibers" may include regenerated cellulose fibers, such as rayon or cuprammonium rayon, and high pulp yield fibers, unless otherwise specified. The term "cellulosic 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 cellulose fibers, cellulose produced by microorganisms, rayon processes, cellulose dissolution and coagulation spinning processes, and other cellulose materials or cellulose derivatives. Other cellulosic fibers are paper break or recycled fibers and high yield pulp fibers. High yield pulp fibers are fibers produced by a pulping process that provides a yield of about 65% or more, more specifically about 75% or more, and even more specifically about 75% to about 95%. The yield is the resulting amount of treated fiber expressed as a percentage of the initial wood mass. Such pulping processes include bleached chemi-thermomechanical pulp (BCTMP), chemi-thermomechanical pulp (CTMP), pressure / pressure thermomechanical pulp (PTMP), thermomechanical pulp (TMP), thermomechanical chemical pulp (TMCP), high yield sulfite pulp, and high yield kraft pulp, all of which leave the resulting fibers with high levels of lignin, yet are considered natural fibers. High yield fibers are known for their stiffness in both dry and wet conditions compared to typical chemically pulped fibers.

[0015] The package of the present disclosure includes a packaging material that contains an absorbent article, the packaging material includes or is derived from a natural resource. That is, the packaging material of the present disclosure includes natural fibers. The natural fibers may form paper from which the packaging material is made. The composition of the packaging material is discussed in more detail herein.

[0016] Package Materials The packaging material of the present disclosure includes natural fibers. The packaging material of the present disclosure may include wood fibers and / or pulp fibers. The packaging material may include at least 50 weight percent natural fibers, at least 70 weight percent natural fibers, at least 90 weight percent natural fibers, about 50 weight percent to about 100 weight percent natural fibers, about 65 weight percent to about 99 weight percent natural fibers, or about 75 weight percent to about 95 weight percent natural fibers, specifically reciting all values ​​within these ranges and any ranges within or formed by these ranges. In one embodiment, the packaging material may include 99.9 weight percent natural fibers.

[0017] Inks, dyes, and / or background colors associated with packaging technology, branding, packaging information, and adhesives associated with seams and barrier coatings are also considered part of the packaging material on a weight percentage basis. If the weight percentage of natural fibers is less than 100 percent, the difference may be made by the inks, dyes, and / or adhesives. The inks, dyes, coatings, and adhesives may be considered contaminants in the paper recycling process, but may otherwise be recyclable.

[0018] Although the packaging material may include many different fibers, inks, dyes, coatings, adhesives, etc., the packaging material of the present disclosure may be constructed to facilitate and / or promote recycling of the packaging material and may promote recycling of the packaging material within a single recycling stream, such as a paper recycling stream. Whether the packaging material is recyclable may vary from region to region. To meet one of the highest standards of recyclability, the total weight percentage of non-recyclable materials, including, for example, inks, dyes, adhesives, and coatings in the packaging material, including materials that are not recyclable within a particular recycling stream, such as a paper recycling stream, but are otherwise recyclable, may be 5 weight percent or less, or 0.1 weight percent to 5 weight percent of the packaging material, specifically recite all values ​​within these ranges and any ranges formed therein. However, other jurisdictions may allow a higher weight percentage of non-recyclable materials. For example, in other jurisdictions, the packaging material of the present disclosure may include 50 weight percent or less, 30 weight percent or less, or about 15 weight percent or less of non-recyclable materials, specifically recite all values ​​within these ranges and any ranges formed therein. As another example, the packaging materials of the present disclosure may include from about 0.1 weight percent to about 50 weight percent, from about 0.1 weight percent to about 30 weight percent, or from about 0.1 weight percent to about 15 weight percent non-recyclable materials, specifically including all values ​​within these ranges and any ranges formed by or within these ranges. In one example, the amount of inks, dyes, coatings, and adhesives is less than or equal to 5 weight percent, or from 0.1 weight percent to 5 weight percent, specifically including all values ​​within these ranges and any ranges formed by these ranges.

[0019] The packaging material of the present disclosure may not include a barrier layer. As used herein, the term "barrier layer" refers to a layer of material, including a barrier coating, a barrier plastic, and / or a barrier foil, bonded to a packaging material that includes natural fibers. Such a barrier layer may reduce the recyclability of the packaging material within a single recycling stream.

[0020] In other cases, the packaging material of the present disclosure may include a barrier layer to at least partially protect the absorbent article disposed within the package. The barrier layer may at least partially inhibit the transfer of water vapor through the packaging material. The barrier layer may include a water-soluble material that may not interfere with the recycling process. The barrier layer may be easily separable from the remainder of the packaging material through the recycling process, for example, by having a different water solubility, density, buoyancy, or other physical mechanism compared to the remainder of the packaging material.

[0021] The type of adhesive utilized for the closure of the package of the present disclosure may also affect the recyclability of the package. As an example, adhesives that are water-soluble during the repulping step or decomposition step of the paper recycling process may be particularly suitable for the package of the present disclosure. 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, Monroe, North Carolina, under the trade name AP0420CR. A suitable example of a polyvinyl acetate-based adhesive is available from Sekisui Chemical Company, Osaka, Japan, under the trade name Selvol205. A suitable example of a polyethylene oxide-based adhesive is available from Dow Chemicals Co., Midland, Michigan, under the trade name WSR N-80.

[0022] Water-dispersible adhesives may be utilized as well. Suitable examples of water-dispersible adhesives include thermoplastic elastomer adhesives and polyvinyl acetate adhesives. A suitable example of a thermoplastic elastomer adhesive is available from Actega, located in Blue Ash, Ohio, under the trade name Yunico 491. A suitable example of a polyvinyl acetate adhesive is available from Bostik, located in Milwaukee, Wisconsin, under the trade name Aquagrip 4419U01. Another suitable example of a polyvinyl acetate adhesive is available from HB Fuller, under the trade name PD-0330.

[0023] Without wishing to be bound by theory, it is believed that packages of the present disclosure utilizing water-soluble adhesives may contain a higher weight percentage of such adhesive than adhesives that are only water-dispersible. For example, a package containing a water-soluble adhesive may contain a first weight percentage of adhesive, and a package containing a water-dispersible adhesive may contain a second weight percentage of adhesive. The first weight percentage may be greater than the second weight percentage for purposes of recycling the packaging material.

[0024] When a barrier layer is utilized, the barrier material may be selected so that the use of adhesives may be reduced or eliminated. One such barrier material may be a polyethylene film coated on the inner surface of the packaging material. Polyethylene may be utilized to form a seal without or in combination with adhesives. However, polyethylene film may not be recyclable in the same stream as other packaging materials, so the weight percentage of polyethylene may follow this description with respect to the percentage of non-recyclable materials discussed herein.

[0025] The effectiveness of the recycling process for the packaging material of the present disclosure can be determined by the recyclable percentage. The packaging material of the present disclosure can exhibit a recyclable percentage of 60 percent or more, 75 percent or more, or 90 percent or more, specifically including all values ​​within these ranges and any ranges formed within these ranges or formed by these ranges. The packaging material of the present disclosure can have a recyclable percentage of about 60 percent to about 99.9 percent, about 75 percent to about 99.9 percent, or about 90 percent to about 99.9 percent, specifically including all values ​​within these ranges and any ranges formed within these ranges or formed by these ranges. In a specific example, the packaging material of the present disclosure can exhibit a recyclable percentage of about 95 percent to about 99.9 percent, specifically including all values ​​within these ranges and any ranges formed within these ranges. The recyclable percentage of the packaging materials of the present disclosure is determined via test PTS-RH:021 / 97 (October 2019 draft) in category II as performed by Papiertechnische Stiftung, Pirnaer Strasse 37, 01809 Heidenau, Germany.

[0026] Along with the recyclable percentage, the total reject percentage is determined via PTS-RH:021 / 97 (October 2019 draft) under the Category II test method. The total reject percentage of the packaging material of the present disclosure may be 40 percent or less, 30 percent or less, or 10 percent or less, specifically including all values ​​within these ranges and any ranges formed by or within these ranges. For example, the total reject percentage of the packaging material of the present disclosure may be about 0.5 percent to about 40 percent, about 0.5 percent to about 30 percent, or about 0.5 percent to about 10 percent, specifically including all values ​​within these ranges and any ranges formed by or within these ranges.

[0027] It is believed that the non-recyclable material percentage does not necessarily have a 1:1 correlation to the total rejection percentage. For example, soluble adhesives and / or coatings are designed to dissolve during the recycling process. It is theorized that these adhesives may not affect the total rejection percentage. However, they will contribute to the non-recyclable material weight percentage.

[0028] PTS-RH:021 / 97 (October 2019 draft) under Category II test method also includes a visual component. Trained screeners inspect one or more handsheets of recycled packaging material for visual defects. If the number of visual defects is too great, the packaging material is rejected. If the number of visual defects is acceptable, according to PTS-RH:021 / 97 (October 2019 draft) under Category II test method, then the packaging material is approved for further processing. The packaging materials of the present disclosure may produce an acceptable level of visual defects during this step of the method.

[0029] The packaging materials of the present disclosure can provide the recyclable percentages previously mentioned as well as pass the visual screening method. Thus, the packaging materials of the present disclosure can achieve an overall score or end result of "pass" when subjected to PTS-RH:021 / 97 (October 2019 draft) under the Category II test method.

[0030] It should also be noted that there are alternative methods for determining the recyclable percentage of the packaging material of the present disclosure. A test method implemented by the University of Western Michigan, called the Redispersibility Test Method, can provide a percent yield of recyclable material. Although there are subtle differences between the Redispersibility Test Method implemented by Western Michigan and PTS-RH:021 / 97 (October 2019 draft) under Category II, the yield of the Redispersibility Test Method is believed to be similar to the recyclable percentage provided by the PTS Test Method.

[0031] It is contemplated that the packaging materials of the present disclosure, while being recyclable, may themselves contain recycled materials. Such a determination can be made from visual inspection of the package. For example, manufacturers typically advertise the use of recycled materials as part of an effort to demonstrate an approach to being an environmentally friendly product. To further elaborate on this example, some manufacturers may utilize a logo, such as a leaf, along with wording indicating that the packaging material uses recycled materials. In many cases, manufacturers may specify the percentage of recycled materials utilized as well, such as more than 50 percent, more than 70 percent, etc.

[0032] Visual inspection can be simple and utilize the human eye to inspect the packaging for logos that use recycled materials. Additionally or alternatively, visual inspection can include microscopy, such as optical microscopy, scanning electron microscopy, or other suitable methods known in the art. For example, packaging materials that contain recycled paper fibers may look different under a microscope due to the presence of a much wider range of natural fiber types than when the packaging material is composed of 100% unrecycled paper. As another example, under a microscope, recycled fibers may show more fibrillated portions than those of their virgin fibers due to their increased processing.

[0033] The packaging material may have some level of strength, stretch, and / or elasticity to withstand the rigors of high speed manufacturing processes where multiple absorbent articles are placed into the package, withstand the forces of compressed absorbent articles placed directly into the package without intermediate packages or containers, withstand the rigors of shipping, provide protection from environmental hazards during shipping and while on the store shelf, and provide product protection while in the consumer's home. The packaging materials of the present disclosure have MD Tensile Strength in kN / m, CD Tensile Strength in kN / m, MD Stretch At Break in percent, CD Stretch At Break in percent, Burst Strength in kPa, Caliper in μm, and J / m 2 Units of MD tensile energy absorption, J / m 2 It may be characterized using metrics such as CD tensile energy absorption in units and basis weight in grams per square meter. Although all metrics may be utilized together to characterize the packaging materials of the present disclosure, it is believed that some of the metrics, alone or in combination with others, may be sufficient to characterize packaging materials that are suitable for packaging absorbent articles. As an example, it is believed that burst strength may be utilized alone or in combination with other metrics to obtain packaging materials that are suitable for packaging absorbent articles. Similarly, it is believed that MD and CD tensile energy absorption (TEA) may be utilized together with each other and, if desired, with any other combination of the metrics described above to obtain packaging materials that are suitable for packaging absorbent articles. As yet another example, it is contemplated that MD break elongation and / or CD break elongation may be utilized together with at least one of MD tensile strength or CD tensile strength, respectively, to characterize packaging materials that may be sufficient for packaging absorbent articles as described herein. Any suitable combination of metrics may be utilized.

[0034] The packaging material of the present disclosure may have a MD tensile strength of at least 5 kN / m, at least 7 kN / m, or at least 8 kN / m, specifically reciting all values ​​within these ranges and any ranges formed therein or formed by these ranges. The MD tensile strength may be from about 5 kN / m to about 8.5 kN / m, from about 5.2 kN / m to about 8.2 kN / m, or from about 5.5 kN / m to about 8.0 kN / m, specifically reciting all values ​​within these ranges and any ranges formed therein or formed by these ranges. The MD tensile strength is measured using the strength tensile test method described herein.

[0035] The packaging materials of the present disclosure may have a CD tensile strength of at least 3 kN / m, at least 4 kN / m, or at least 5.5 kN / m, specifically recited herein all values ​​within these ranges, and any ranges within or formed by these ranges. The CD tensile strength may be from about 3 kN / m to about 6.5 kN / m, from about 3 kN / m to about 6.2 kN / m, or from about 3 kN / m to about 6 kN / m, specifically reciting all values ​​within these ranges and any ranges formed by or within these ranges. The CD tensile strength is measured using a strength tensile test method.

[0036] The packaging material of the present disclosure may have a burst strength of at least 200 kPa, at least 250 kPa, or at least 550 kPa, specifically reciting all values ​​within these ranges and any ranges formed by or within these ranges. The burst strength of the packaging material of the present disclosure may be from about 200 kPa to about 600 kPa, from about 220 kPa to about 550 kPa, or from about 250 kPa to about 500 kPa, specifically reciting all values ​​within these ranges and any ranges formed by or within these ranges. Burst strength is measured using the burst strength test method described herein. As measured, burst strength is believed to include components of strength, flexibility, and resilience. As such, it is believed that burst strength may be used independently of the other metrics mentioned.

[0037] In addition to strength, the packaging materials of the present disclosure may also exhibit some degree of elasticity. Thus, the packaging materials of the present disclosure may exhibit an MD elongation at break of at least 3 percent, at least 4 percent, or at least 6 percent, specifically reciting all values ​​within these ranges, and any ranges within or formed by these ranges. The packaging materials of the present disclosure may exhibit an MD elongation at break of about 3 percent to about 6.5 percent, about 3.2 percent to about 6.2 percent, or about 3.5 percent to about 6 percent, specifically reciting all values ​​within these ranges, and any ranges within or formed by these ranges. The MD elongation at break is measured using the strength tensile test method described herein.

[0038] The packaging materials of the present disclosure may exhibit a CD elongation at break of at least 4 percent, at least 6 percent, or at least 9 percent, specifically reciting all values ​​within these ranges and any ranges formed within or by these ranges. The packaging materials of the present disclosure may exhibit a CD elongation at break of about 4 percent to about 10 percent, about 4.5 percent to about 9.5 percent, or about 5 percent to about 9 percent, specifically reciting all values ​​within these ranges and any ranges formed within or by these ranges. The CD elongation at break is measured using the strength tensile test method described herein.

[0039] With respect to caliper, the packaging material of the present disclosure may exhibit a caliper of at least 50 μm, at least 70 μm, or at least 90 μm, specifically reciting all values ​​within these ranges and any ranges within or formed by these ranges. The packaging material of the present disclosure may exhibit a caliper of about 50 μm to about 110 μm, about 55 μm to about 105 μm, or about 60 μm to about 100 μm, specifically reciting all values ​​within these ranges and any ranges within or formed by these ranges. Caliper is measured using the caliper test method described herein.

[0040] In terms of tensile energy absorption (TEA), the packaging material of the present disclosure has a tensile energy absorption of at least 150 J / m 2 , 170J / m 2 More than or at least 180 J / m 2 and specifically recites all values ​​within these ranges, and any ranges formed within or formed by these ranges. The packaging material of the present disclosure may exhibit a TEA of about 100 J / m 2 ~about 250J / m 2 , about 125J / m 2 ~Approx. 225J / m 2 , or about 150 J / m 2 ~About 200J / m 2and specifically recites all values ​​within these ranges, and any ranges within or formed by these ranges.

[0041] The packaging material of the present disclosure has a resistance of at least 150 J / m 2 , at least 200 J / m 2 , or at least 250 J / m 2 and specifically recites all values ​​within these ranges, and any ranges formed within or formed by these ranges. The packaging material of the present disclosure may have a TEA of about 150 J / m 2 ~About 275J / m 2 , about 175J / m 2 ~about 260J / m 2 , or about 200 J / m 2 ~about 250J / m 2 and specifically recites all values ​​within these ranges, and any ranges formed by or within these ranges. The TEA in MD and CD is measured according to the Tensile Strength Test Method described herein.

[0042] The basis weight of the packaging material can affect the "feel" of the package to the consumer as well as the strength of the package. If the basis weight is too low, the package can feel too thin. If it is too high, the package may feel too inflexible. The packaging material of the present disclosure has a basis weight of about 50 gsm to about 120 gsm, about 55 to about 115 gsm, or about 60 gsm to about 110 gsm, specifically reciting all values ​​within these ranges and any ranges formed within or by these ranges. Basis Weight, also referred to as "grammage", is determined according to the basis weight test method described herein.

[0043] It should be noted that for high speed packaging processes, the lower basis weight of 50 gsm may result in some loss of quality assurance. It is believed that high speed packaging processes may cause distortions on the packaging material that slower packaging processes do not. Thus, if the packaging material is processed using a high speed manufacturing process, 60 gsm may be a minimum desirable packaging material basis weight. If the packaging material is processed using a hand-filling process or a slower packaging process, 50 gsm may be sufficient as a minimum packaging material basis weight.

[0044] The packaging materials of the present disclosure are different from cartonboard and corrugated board. For example, cartonboard is not as flexible as the packaging materials of the present disclosure. Cartonboard is inherently more rigid than the packaging materials of the present disclosure and does not have the processability for high speed converting lines as the packaging materials of the present disclosure. Additionally, cartonboard has a basis weight of over 160 gsm, which is significantly higher than the basis weight of the packaging materials of the present disclosure.

[0045] Similarly, cardboard is also different from the packaging materials of the present disclosure. Cardboard has a much higher basis weight (over 200 gsm) than the packaging materials of the present disclosure. Furthermore, cardboard is much less flexible than the packaging materials of the present disclosure. Cardboard materials are generally fluted and include three plies of paper material, and thus are structurally different from the packaging materials of the present disclosure.

[0046] The packaging material of the present disclosure has the advantage of being more flexible compared to carton board and corrugated board. Another advantage is that the packaging material of the present disclosure takes up less space than the bulkier carton board and corrugated board. A further advantage of the packaging material of the present disclosure, at least in part due to the strength and resilience properties discussed herein, is that the packaging material allows the packaged absorbent article to be compressed within the package. This allows more products to fit into a smaller volume package, which may increase manufacturing efficiency. One additional advantage is that a single layer (one ply) of the packaging material of the present disclosure can form the package of the present disclosure. The inventors have found that the package of the present disclosure can be formed from a single layer (one ply) of the packaging material of the present disclosure, at least in part due to the flexibility, strength, and resilience properties of the packaging material.

[0047] For example, despite having less flexibility compared to plastic packaging and a lower basis weight than corrugated board and carton board, the inventors have surprisingly found that the packaging material of the present disclosure can withstand the rigors of high speed manufacturing processes where multiple absorbent articles are placed within a package under compression, and during shipping, provide protection from environmental hazards during shipping and while on store shelves, and provide protection for the absorbent articles while in the consumer's home.

[0048] Table 1 shows various packaging materials that can be successfully used in packaging absorbent articles under high speed processing conditions, along with at least one packaging material that does not work. Various properties previously discussed are also listed for each sample.

[0049] Sample 1: A packaging paper made from pure white kraft pulp and consisting of completely virgin fibers, available from BillerudKorsnas™ under the trade name Axello Tough White.

[0050] Sample 2: A packaging paper made from pure white kraft pulp and consisting of completely virgin fibers, available from BillerudKorsnas™ under the trade name Performance White SE.

[0051] Sample 3: A calendered specialty kraft paper made from completely virgin fibers available from Mondi™ under the trade name Advantage Smooth White Strong.

[0052] Sample 4: A packaging paper produced from kraft pulp made from virgin fibers and containing a fluoropolymer barrier coating, available from BillerudKorsnas™ under the trade name Basix Glaze.

[0053] [Table 1]

[0054] The packaging material of Sample 4 cannot be successfully used in packaging absorbent articles. During placement of the absorbent article in the package, the packaging material was torn. Without wishing to be bound by theory, it is believed that Sample 4 fails due to a combination of low basis weight and high speed packaging process. Although Sample 4 fails under high speed process conditions, it is believed that a sample with the properties of Sample 4 may be successful using a gentler packaging process such as hand stuffing.

[0055] Package Configuration The packaging material of the present disclosure may be arranged as a package in a myriad of configurations to house absorbent articles. For example, the package may include multiple panels that define interior compartments and enclose one or more absorbent articles. When in a sealed state, such as during shipping and on display on a store shelf, the package may completely enclose one or more absorbent articles. Each of the panels includes an inner surface that faces inwardly toward the packaged absorbent article and an outer surface that faces outwardly toward the consumer. The outer and / or inner surfaces of one or more panels may include inks or dyes that create branding, packaging information, and / or background colors on the package. Branding and / or packaging information associated with the absorbent articles within the package may be provided on the outer surface of at least one panel. Branding may include logos, trade names, trademarks, icons, and the like associated with the absorbent articles within the package. Branding may be utilized to inform consumers of the brand of the absorbent articles within the package. As an example, the brand of a package of feminine hygiene pads may include the trade name Always®. The packaging information may include the size of the absorbent article, the number of absorbent articles in the package, an exemplary image of the absorbent articles contained in the package, a logo indicating that the absorbent articles are recyclable, and the like. As an example, the packaging information for a package of feminine hygiene pads may include a size indicator, e.g., "Size 1."

[0056] The packaging material of the present disclosure may be provided to the absorbent article manufacturer by the packaging material manufacturer. The packaging material may be somewhat preformed into a finished package shape, or the packaging material manufacturer may simply provide a roll of packaging material to the absorbent article manufacturer. The packaging material may be unitary, meaning that the package is formed from a single piece of packaging material. For example, multiple folds and seams may be utilized to form multiple panels of the package from a single piece of packaging material. In such an example, the absorbent article manufacturer may create the folds and seams as described herein to form a package for the absorbent article. The package of the present disclosure may include a packaging material that includes multiple separate portions. Such configurations are described in further detail herein.

[0057] Regardless of whether the packaging material is on a roll or preformed to some degree, the packages of the present disclosure begin with paper stock. With reference to Figures 1A-1B, edges 100 and 110 of a paper stock sheet 99 may be folded toward one another and subsequently sealed to form a seam. For example, sides 100 and 110 of the sheet 99 may move inward toward the longitudinal centerline 90 of the sheet 99 to form a hoop seam 95 (see Figure 1C). These edges may be overlapped and sealed together to form an overlap seam. Alternatively, edges 100 and 110 may be joined together on their respective inner surfaces to form a butt seam. Butt seams tend not to lie flat in the same way as overlap seams. Thus, if the seam is located, at least in part, on a bottom panel on which the package may rest, an overlap seam may be desirable so that the package may rest on a flatter bottom panel.

[0058] 1C-1E, a sheet of packaging material may be suitably folded to form bag side creases 12b and 13b and two side creases 12a and 13a on the opposite side to form a bag structure 4 having a first surface 10, second and third surfaces 12, 13, and fourth and fifth surfaces 14, 15, respectively. An open end 48 is opposite the first surface 10. Each side crease 12b, 13b may be located on the respective second or third surface 12, 13. Note that in FIGS. 1C and 1D, the creases and folds shown are for a package having a block configuration or a block bottom configuration. Gussets and fold lines for pinch bottom bags are discussed in more detail with respect to FIG. 2B.

[0059] The bag 4 may be filled by inserting articles, such as a plurality of absorbent articles, through the open end 48. For example, when the bag 4 is filled with a plurality of articles by inserting the articles through the open end 48, the device used to introduce the articles into the bag 4 and the articles may exert some tension on each of the second and third surfaces 12, 13 of the bag 4. For example, the articles may be compressed before being inserted into the bag 4, so that the articles may expand slightly after being introduced into the bag 4 and therefore exert some tension on the second and third surfaces 12, 13, as well as the fourth and fifth surfaces 14, 15. This tension may be exerted on each of the creases 12b, 13b, particularly on the first and second side folds 12a, 13a, as well as on the second and third surfaces 12, 13, respectively, thereby allowing the package to maintain a substantially parallelepiped shape.

[0060] As can be seen from FIG. 1D, the open end 48 opposite the first surface 10 can then be closed to form the sixth surface 11. Any suitable style of closure can be utilized. In one form, the sixth surface can include a closure gusset 11b, with the portion of the outer surface of the packaging material at the closure gusset 11b forming a closure seam 11a and a closure seam fin 11c extending from the sixth surface 11. At least a portion of the closure seam fin 11c can be attached to at least a portion of the sixth surface 11. Tacking the closure seam fin 11c to at least a portion of the sixth surface can reduce the risk of unintentional opening of the package, provide increased stickiness, and provide a cleaner appearance on the shelf as well. Instead of forming a closure gusset and a closure fin, the sixth surface can include seams joined together in a block-style or cross-style configuration, as discussed further herein.

[0061] One example of a block style configuration is shown in FIG. 2A. As shown, the first surface 10 may include block style seams 220 and 230. The first surface 10 may have a base portion 240. A first flap of packaging material 250 may be folded over the base portion 240. The first seam 220 may be provided to attach the first flap of packaging material 250 to the base portion 240. A second flap of packaging material 260 may be folded over the base portion 240 and over the first flap of packaging material 250. The second seam 230 may be provided to attach the second flap of packaging material 260 to the base portion 240 and the first flap of packaging material 250. A similar implementation may be utilized to form a closure for the sixth surface 11.

[0062] Another example of a panel seal style that may be utilized with the package of the present disclosure is a pinch style configuration or pinch bottom style. One example of a pinch style 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 creases 12b and 13b. Instead of pleats on the sides 12 and 13, the pinch style configuration includes gussets 22b and 23b on the first surface 10. Additionally, in the pinch bottom configuration, the first surface 10 includes a crease line 10a that may not be present in the block style configuration. A similar pinch style configuration may be utilized with respect to the sixth surface 11 to form a closure.

[0063] A cross-style or cross-bottom style configuration is also acceptable for sealing portions of the packaging material of the present disclosure. One example of a cross-style configuration is shown in FIG. 2C. As shown, one of the key differences between the cross-style and block-style configurations is that the gussets 32b and 33b and the fold lines 12a and 13a are oriented outwardly of the interior of the package. In the block-style 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 inwardly before filling the package. Due to the orientation of the gussets 32b and 33b in the cross-style configuration, filling the package with absorbent articles may require less energy to expand the package for filling. As an example, inwardly oriented creases, such as in the block-style configuration, require outward displacement of the creases before filling the package. Additionally, equipment utilized in directing the product into the package may be less likely to interfere with the gussets given their outward orientation. This may reduce the possibility of packaging accidents or production process stoppages due to quality issues.

[0064] 2C, similar to the block style configuration, the first surface 10 of the cross style configuration includes seams 320 and 330. The first surface includes a base portion 340. A first flap of the packaging material 350 may be folded over the base portion 340. A first seam 320 may be provided to attach the first flap of the packaging material 350 to the base portion 340. A second flap of the packaging material 360 may be folded over the base portion 340 and over the first flap of the packaging material 350. A second seam 330 may be provided to attach the second flap of the packaging material 360 to the base portion 340 and / or the first flap of the packaging material 350. A similar implementation may be utilized to form a closure on the sixth surface (formed once the package is sealed after placement of an absorbent article therein).

[0065] For less bulky items where package uprightness is desired, a block or cross bottom may be desirable as these configurations provide a flat base, however for bulkier items, a pinch style configuration bag may be beneficial as the bulky absorbent article therein may provide a stable base for the package to stand upright. The inventors have surprisingly found that diapers, due to their bulky nature, may be suitable for pinch bottom bags. In contrast, feminine hygiene articles, particularly menstrual pads, may be suitable for packaging in a block bottom configuration.

[0066] Additionally, it should be noted that block-style and cross-style packages tend to be bulkier themselves than their pinch-style counterparts. For the purpose of packaging absorbent articles, unfilled packages may arrive to absorbent article manufacturers in preformed stacks. Typically, preformed stacks of block-style and cross-style packages will take up more space compared to preformed pinch-style packages due to their bulkiness. The bulkiness of block-style and cross-style configurations may make it more difficult to manipulate the stacks during the filling process, especially when a large number of filled packages are made per minute. In such cases, the bulkiness of these configurations may mean increased frequency of stack refills.

[0067] Referring again to FIGS. 1C-1D, the first surface 10 may form at least a portion of the top panel of the package 1. In another embodiment, the first surface 10 may form at least a portion of the bottom panel of the package 1. Note that if the first surface 10 includes a seam, it may be desirable for the first surface 10 to form at least a portion of the bottom panel. In this way, the seam may be hidden from view on a store shelf. The second and third surfaces 12 and 13 may include gussets 12b and 13b, respectively, and thus may form at least a portion of a first side panel and an opposing second side panel, respectively, or vice versa. The fourth and fifth surfaces 14, 15 may form at least a portion of a front panel and an opposing rear panel, respectively, or vice versa. At least one of the fourth and / or fifth surfaces 14, 15 may include branding, product information, and / or background color as described herein, since the front panel is generally the panel facing the consumer. However, the product information and / or background color may not be limited to the panel facing the consumer. Any combination of panels of the packages of the present disclosure may include branding, product information, and / or background color. The sixth surface 11 may form at least a portion of the top panel or at least a portion of the bottom panel of the package 1. It may be desirable for the sixth surface 11 to form at least a portion of the top panel, where the sixth surface 11 includes a closure gusset 11b, a closure seam 11a, and a closure seam fin 11c extending from the closure seam 11a. In this way, the closure gusset 11b and the closure seam fin 11c do not introduce bulk and instability to the base of the package. Where the sixth surface 11 forms at least a portion of the top panel, top edge region 11d is formed at the transition from the top panel to the front, rear, and first and second side panels. Top edge region 11d may be formed by portions of the top, front, rear, first side, and second side panels adjacent a fold in the packaging material that designates the transition from the top panel to another panel.

[0068] The closing seam fin 11c may include a carrying handle 1200, as shown in Figures 6, 12A-16, and 18A. The carrying handle 1200 may be formed by a portion of the closing seam fin 11c that is free of packaging material. In one form, at least a portion of the packaging material forming the closing seam fin 11c may be cut away to define the carrying handle 1200. The carrying handle 1200 may be configured to allow a user to engage the carrying handle 1200 without having to grip the handle with the user's hand. For example, the carrying handle 1200 may be sized to allow a user to slip their entire hand through the carrying handle 1200 and hook the carrying handle 1200 around the user's wrist, thus keeping the user's hand free. Thus, the area defining the carrying handle 1200 may be at least 100 cm 2 , at least 150cm 2 , at least 200 cm 2 , or at least 250 cm 2 may be measured.

[0069] Other package shapes are contemplated. Examples of such packages include flow wrap or horizontal form fill and seal wrap. Such packages may include a generally rectangular shape as configured above. However, in some cases, as shown in FIG. 17, a flow wrap package 1700 may include a first surface 1702 and an opposing second surface 1704. A rounded edge may be provided as a transition between the first surface 1702 and the second surface 1704. In another form, one or more fold lines may be provided between the first surface 1702 and the second surface 1704. The flow wrap package 1700 may further include end seals 1706 and 1708 and a hoop seam 1709 that may be disposed on the second surface 1704. In such packages, the first surface 1702 may include a panel that faces the consumer. Flow wrap packages may be useful, particularly when a small number of absorbent articles are included in the package.

[0070] Alternative package configurations according to the present disclosure may include more explicitly moving seams / seals than packages including block bottoms, pinch bottoms, and / or cross bottoms. Referring to FIG. 18, package 1800 is shown. Package 1800 may be configured in a generally rectangular parallelepiped shape. Package 1800 may 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 first panel 1811. As shown, a first seal 1820 extends outwardly between fourth panel 1814 and sixth panel 1810. First seal 1820 may form a kind of foot for package 1800. A second seal (not shown) may extend outwardly between the fifth panel 1815 and the sixth panel 1810 in a manner similar to the first seal 1820.

[0071] The first seal 1820 can extend such that a portion of the first seal 1820 is on the second panel 1812 and another portion of the first seal 1820 is disposed on the third panel 1813. Similarly, a portion of the second seal can be disposed on the second panel 1812 and another portion can be disposed on the third panel 1813. The first seal 1820 and the second seal can be provided where the sixth panel 1810 is formed from a separate piece of material that is subsequently joined to the fourth panel 1814 and the fifth panel 1815. Of course, configurations in which the sixth panel 1810 is integral with the fourth panel 1814 and the fifth panel 1815 are also contemplated.

[0072] The third seal 1830 and the fourth seal 1840 may extend outwardly from the second panel 1812 and the third panel 1813, respectively. It should be noted that the first seal 1820, the second seal, the third seal 1830, and the fourth seal 1840 may collectively comprise a hoop seal as discussed herein. Thus, one, all, or any combination of these seals may exhibit the tensile strength of a hoop seal as described herein.

[0073] As shown, the package 1800 may further include a fifth seam 1850 disposed on the sixth panel 1811 and a sixth seam 1860. The fifth seam 1850 and the sixth seam 1860 may extend into the sealing fin 1880. It is noted that the package 1800 and its associated seams may be assembled as described herein with respect to adhesives, barrier films, and / or combinations of barrier films and adhesives. However, the construction of the package 1800 is particularly well suited for the creation of seams via a barrier film coating on the interior surface of the packaging material. In such a configuration, the film may form a barrier that reduces the likelihood, or at least the amount, of water vapor passing through the packaging material to absorbent articles therein.

[0074] Package shapes are also contemplated where the package includes fewer than six panels. Packages having a circular or semicircular shape when viewed from the bottom panel are contemplated. Additionally, packages that are triangular when viewed from the bottom panel are contemplated. Regardless of the number of panels included in a package of the present disclosure, the package includes a panel that faces the consumer.

[0075] Configuration of absorbent article The package of the present disclosure may include one or more absorbent articles. The absorbent articles may be placed in the package in an unfolded or folded configuration. The articles may be folded laterally and / or longitudinally. The articles may include one fold line and be disposed in the package in a bi-fold configuration. The articles may include two fold lines and be disposed in the package in a tri-fold configuration.

[0076] FIG. 3A depicts one embodiment of a feminine hygiene pad in an unfolded configuration. FIG. 3B depicts a side view of the feminine hygiene pad of FIG. 3A in a tri-fold configuration. The feminine hygiene pad depicted in FIG. 3A and FIG. 3B includes a first fold line 3400 disposed between a first end region of the pad 3100 and a central region of the pad 3300, and a second fold line 3402 disposed between a second end region of the pad 3200 and the central region 3300. Prior to placement in a package, the second end region 3200 may be folded longitudinally inward about the second fold line 3402 to overlap at least a portion of the central region 3300, as can be seen from a comparison of FIG. 3A and FIG. 3B. The first end region 3100 may then be folded longitudinally inwardly about the first fold line 3400 such that it overlaps at least a portion of the central region 3300 and a portion of the second end region 3200. In some embodiments, a tri-fold configuration may have the article folded approximately in thirds about two longitudinally spaced lateral creases.

[0077] 4A-4D depict an absorbent article in the form of a diaper 4000 including front and rear waist edges 4100, 4200 in successively opened / unfolded and folded configurations. When packaged in bulk, a plurality of diapers such as the one depicted in FIG. 4A may each be folded laterally inwardly, overlapping its longitudinal side edges, in a possible first step, about a longitudinal side edge fold line 4300, as can be seen from a comparison of FIG. 4A with FIG. 4B. Subsequently, in a second step, the diaper may be folded longitudinally about a lateral fold line 4400 passing through the crotch region of the diaper, as can be seen from a comparison of FIG. 4B with FIG. 4C. For a bi-fold configuration as depicted in FIG. 4C and FIG. 4D, the article may be folded once longitudinally, and in some embodiments, approximately in half, about the lateral fold line 4400.

[0078] Regardless of whether the article is in a bi-fold or tri-fold configuration, a folded article, such as a folded feminine hygiene pad 3000 and / or a folded diaper 4000, may have a single fold tip 30 that defines at least one edge of the folded article, a fold tip corner 32, and left and right longitudinal perimeter edges 4500, 4600. It will be appreciated that in tri-fold embodiments, a single fold tip may define each of both end edges of the folded article. In some embodiments, such as those depicted in Figures 4C and 4D, the fold tip 30 may be proximate the crotch region of the article (the middle region of the article adapted to be located between the legs of a wearer during wear). The folded article has a folded width FW, measured as the distance between the side edges, a folded height FH, measured as the distance between the fold tip 30 and the end edge (in a bi-fold configuration) or between the two fold tips 30 (in a tri-fold configuration), and a lateral width (SW). The folded width (FW) forms the flat, broad side of the folded absorbent article, while the lateral width (SW) forms the narrow, folded side of the absorbent article.

[0079] A plurality of folded articles such as those depicted in Figures 3B and 4C and 4D may be placed in a similar orientation within an interior compartment of a package of the present disclosure. Figures 5 and 6 depict a plurality of absorbent articles disposed within a package of the present disclosure. As shown in Figures 5 and 6, a package 1000 defines an interior compartment 1002 in which a plurality of absorbent articles 1004 are placed. The absorbent articles 1004 may 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 two or more vertical stacks, as shown in FIG. 6, all of the articles may be oriented in the same direction. In another embodiment, a first set of folded articles may have their fold tips 30 oriented along one side of the stack, and a second set of folded articles may have their fold tips rotated 180 degrees and oriented along the opposite side of the stack. In some embodiments, the first set of articles and the second set of articles may appear in alternating order within the stack.

[0080] The folded absorbent articles may be disposed in the package of the present disclosure such that the folded width (FW) faces toward the first and second side panels. Such a configuration may be used when the number of absorbent articles in the package is relatively large, e.g., greater than about 10 individual absorbent articles, since the narrower sides (SW) of the articles form the front and back panels. Thus, a relatively large number of absorbent articles may be utilized to construct the front and back panels of the package. Such a configuration may be beneficial when the front and / or back panels form the consumer-facing panels.

[0081] The folded absorbent articles may be disposed in the package of the present disclosure such that the folded width (FW) faces toward the front and back panels. Such a configuration may be used when the number of absorbent articles in the package is relatively small, e.g., less than about 10 individual absorbent articles, since the wider side (FW) of the article forms the front and back panels. Such a configuration may be beneficial when the front and / or rear panels form the consumer-facing panels and the number of absorbent articles disposed within the package is less than about 10.

[0082] The absorbent article(s) can be packaged under compression to reduce the size of the package while providing an adequate number of absorbent articles per package. By packaging absorbent articles under compression, the package can be easily handled and stored by caregivers, and the reduced package size can also provide manufacturers with reduced distribution costs. Despite lacking the stretch properties of traditional plastic packaging materials, the inventors have surprisingly found that the packaging materials of the present disclosure can withstand the rigors of processing and dispensing, even for absorbent articles that are compressed in the package and do not use intermediate containers, as referred to herein. This is particularly unexpected, since the materials of the present disclosure may not display the stretch properties of traditional plastic films currently in use.

[0083] A package of absorbent articles of the present disclosure may have an In-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 according to the In-Bag Stack Height Test described herein, specifically recited within the specified ranges, and all increments of 0.1 mm within or formed by these ranges. Alternatively, the package of absorbent articles of the present disclosure may have an in-bag stack height of about 70 mm to about 150 mm, about 70 mm to about 110 mm, about 70 mm to about 105 mm, about 70 mm to about 100 mm, about 70 mm to about 95 mm, about 70 mm to about 90 mm, about 70 mm to about 85 mm, about 72 mm to about 80 mm, or about 74 mm to about 78 mm according to the In-Bag Stack Height Test Method described herein, specifically reciting all increments of 0.1 mm within the ranges specified, and all ranges within or formed by these ranges.

[0084] Opening mechanism The package of the present disclosure containing absorbent articles includes a mechanism (opening mechanism) that facilitates opening without unwanted deformation or destruction of the package, so that the opened package may be used after opening as a container for storing a supply of unused product. The opening mechanism includes a weakened area or multiple weakened areas. The inventors have surprisingly found that the package of the present disclosure having a balance between the strength properties of the packaging material and the strength properties of the weakened area may provide a flexible and resilient package that can withstand the rigors of the manufacturing process while providing an opening mechanism configured to facilitate package opening and minimize distortion of the packaging material along the path during opening. The package of the present disclosure may also retain its shape upon removal of the absorbent article, which may make it easier to remove further articles.

[0085] The weakened areas have a tensile strength less than that of the non-weakened areas of the package to allow the package to be opened at the weakened areas while the non-weakened areas of the package remain intact, however, the tensile strength of the weakened areas may be sufficient to withstand unintentional opening during package formation, shipping, store display, and everyday use by consumers.

[0086] The inventors have also found that forming the weakened area may be more efficient and less cumbersome when the package is formed from a single layer (one ply) of packaging material, as opposed to multiple layers.As discussed herein, the packaging material of the present disclosure may allow the formation of a package that includes a single layer of packaging material while exhibiting sufficient strength and resilience.The arrangement of the weakened area in a single layer (one ply) of packaging material may require less energy and time compared to the arrangement of the weakened area through multiple layers of material.

[0087] The weakened areas may include folds disposed within the packaging material configured to render the weakened areas less resistant to tearing or puncturing than the unfolded portion of the packaging material. The weakened areas may also, or instead, include perforations and / or scores within the packaging material. The perforations and / or scores may form a path or paths along a portion or portions of the packaging material. The path may be continuous. For purposes of this specification, a "continuous" path of perforations or scores is a single path of individual continuous mechanically generated partial or complete perforations, a single path of individual continuous laser scored partial or complete perforations, or a single path of continuous mechanical and / or laser scores that is not interrupted by non-perforated / non-scored portions of the packaging material. The packages of the present disclosure may include a single path of perforations and / or scores or may include multiple paths. The path or paths of perforations and / or scores may form a substantially straight line or may form a curved shape.

[0088] 7A-7E, the individual perforations and / or scores defining the pathway 60 may have any configuration suitable for propagating a tear in the packaging material along the pathway. When the perforation and / or score pathway 60 includes a plurality of individual mechanically created perforations or cuts or individual laser cut perforations or cuts, it may be desirable for the pathway to have a cut-to-land ratio of about 0.7:1 to about 6:1, about 0.8:1 to about 5:1, or about 1:1 to about 4:1, specifically reciting all values ​​within these ranges, and any ranges formed within or by these ranges. For the types of packaging materials contemplated herein, a land-to-slit ratio within this range is believed to strike a suitable balance between providing ease of opening the package and minimizing distortion of the packaging material along the path during opening, and avoiding premature, inadvertent package rupture or opening prior to intentional opening by the consumer, and preserving the structural integrity of the package during formation, transportation, handling, and other events. For purposes of this specification, the "land-to-slit ratio" of a perforation and / or score path is the ratio of the set of perforation or score lengths extending along the path direction to the set of minimum distances of unperforated / unscored portions of packaging material between successive perforations. For example, referring to FIG. 8, in which a portion of a continuous, obliquely slanted rectangular perforation path is depicted lying along the path direction PD, the land-to-slit ratio is (L1+L2+L3):(D1+D2+D3).

[0089] The individual perforations and / or scores may include any configuration capable of forming a weakened region. As shown in FIG. 7A, the individual perforations and / or scores 66 may be in the form of a straight line. As shown in FIG. 7A, the straight line perforations and / or scores may be aligned substantially parallel to the perforation and / or score path 60. As shown in FIG. 7B, the individual perforations and / or scores 66 may be aligned such that each individual perforation and / or score is disposed at an angle relative to the perforation and / or score path 60. The angle may be between about 20° and about 80°. Referring to FIG. 7E, the individual perforations and / or scores 66 may include a first leg 61 and a second leg 63. The first leg 61 may be disposed substantially parallel to the perforation and / or score path 60. The second leg 63 may be disposed at an angle relative to the perforation and / or score path 60. The angle may be from about 20° to about 80°. In another embodiment, the second leg 63 may be disposed substantially parallel to the perforation and / or score path 60 and the first leg 61 may be disposed at an angle relative to the perforation and / or score path 60, the angle may be from about 20° to about 80°. With reference to FIG. 7C, each perforation and / or score 66 may include three legs, at least one of which may be disposed at an angle relative to the perforation and / or score path 60, the angle may be from about 20° to about 80°. Weakened areas including perforations and / or scores that include at least one leg disposed at an angle to the path of the perforations and / or scores may exhibit lower tensile strength but are believed to be more resistant to tearing and accidental opening during the manufacturing process.

[0090] 9A-9E, a package of the present disclosure includes a weakened region including multiple paths of perforations and / or scores 60, which may be separated by aligned land areas 62. The aligned land areas 62 may have a length greater than the land areas of the paths they separate, when measured in line with the adjacent paths. The length of the aligned land area may be large enough to distinguish it from the land areas of adjacent paths of perforations and / or scores, but may not be large enough to prevent opening of two adjacent paths upon one application of force from a user. The aligned land areas may coincide with a crease or fold in the packaging material, such as at a corner between two panels. The aligned land areas may be pre-weakened or may help prevent unintentional opening of the opening mechanism in portions of the package that may experience some increased amount of stress due to the placement of the weakened region over the creases and / or folds in the package. The registered land areas may have lengths from about 1.5 mm to about 25 mm, from about 2 mm to about 20 mm, or from about 2 mm to about 10 mm, and specifically recite all increments of 0.1 mm within the ranges specified, and all ranges within or formed by these ranges.

[0091] The perforation and / or score path may include a single, uninterrupted laser score line that does not penetrate completely through the packaging material, but is configured to promote smooth tear propagation along the path. The uninterrupted laser score line may be disposed on the packaging material coincident with the fold lines, or may be disposed on a flat portion of the packaging material. The placement of a single, uninterrupted laser score line coincident with the fold lines may enhance the ability of an already weakened region to tear or rupture along a designated path upon application of sufficient force, while the remainder of the package retains its shape and integrity.

[0092] Referring again to Figures 7A-7E, the configuration of the perforations in the perforation path 60 may depend on the location on the package where the weakened area is disposed. A perforation configuration with a higher cut-to-land ratio may be desirable in a weakened area that includes a perforation path that crosses a gusset structure, since the gusset structure includes two or more layers of packaging material and may be more difficult to tear. Additionally, when multiple absorbent articles are packaged in a package of the present disclosure under compression, the perforation configuration may be arranged such that at least a portion of the cut direction is disposed diagonally or perpendicular to the direction of tension in the packaging material created by compression of the absorbent articles, as shown in Figures 9B, 9C, and 9E. In such a configuration, the perforations are believed to be less likely to stretch and / or open prior to intentional opening by the consumer.

[0093] 10 and 11, it may be desirable to include a stress distribution feature 69 proximate one or both of the endpoints 64, 65 of the perforation and / or score path 60 to reduce the chance that a consumer opening the package will tear the packaging material beyond the endpoints 64, 65, deforming the packaging material and / or reducing the usefulness of the package for storing and / or protecting unused items. As shown in FIGS. 10 and 11, the tear stress distribution feature 69 is a semicircular perforation or cut that runs transverse to the direction of the path 60, which serves to distribute the tear stress concentrated at the endpoints and impede the propagation of the tear in a manner that can be tactilely perceived by the consumer. It will be appreciated that the tear stress distribution feature 69 may have other configurations, including other shapes of cuts and / or perforations through the packaging material that extend transverse to the direction of the path 60 and are supplemented with reinforcing strips, tapes, and the like.

[0094] FIG. 12A is a perspective view of a package of the present disclosure in a closed configuration, and FIG. 12B shows the package of FIG. 12A in a partially opened configuration. With reference to FIGS. 12A and 12B, the package 1 of the present disclosure may include a top panel 11 including a closure gusset 11b, a closure seam 11a, and a closure seam fin 11c. A weakened area 700 may be disposed on at least a portion of the closure seam fin 11c between the closure seam 11a and an interior compartment 702 that includes one or more absorbent articles. The weakened area 700 may traverse at least a portion of the closure gusset 11b. The weakened area 700 may include a series of perforations and / or scores 704. The series of perforations and / or scores 704 may form a path that is substantially parallel to the closure seam 11a. The path of the perforations and / or scores may have a relatively high cut-to-land ratio. A relatively high cut-to-land ratio may be preferred when the closure gusset portion includes four layers of packaging material and the perforation and / or score path traverses at least a portion of the closure gusset because a higher cut-to-land ratio can reduce the amount of force required to form an opening in the package. For example, the cut-to-land ratio can be from about 0.7:1 to about 6:1, or from about 1:1 to about 6:1, or from about 2:1 to about 6:1, specifically reciting all values ​​within these ranges, and any ranges formed within or formed by these ranges.

[0095] The weakened areas may be configured to form an opening along a path of perforations and / or scores. The weakened areas 700, including a series of perforations and / or scores 704, may be configured to allow the closing seam fin 11c to be completely removable from the remainder of the package 1. In such a configuration, removal of the closing seam fin 11c may provide a large opening defined by the front panel 14, the rear panel 15, and the first and second side panels 12, 13 to allow easy access to absorbent articles disposed within the interior compartment 702. An additional benefit of the large opening created by complete removal of the closure seam fin is that the absorbent article may be configured in any manner within the interior compartment and still be easily removable.

[0096] 13A is a perspective view of a package of the present disclosure in a closed configuration, and FIG. 13B shows the package of FIG. 13A in a partially opened configuration. With reference to FIGS. 13A and 13B, the package 1 of the present disclosure may include a weakened area 700 disposed on at least a portion of a top edge region 706 of the package 1 in at least one of the top panel 11-front panel 14, the top panel 11-rear panel 15, the top panel 11-first side panel 12, and the top panel 11-second side panel 13. If the top panel 11 includes a closure gusset 11b, the weakened area 700 may be disposed below the closure gusset 11b. Since only the area of ​​the package outside the closure gusset includes a single layer of packaging material, a relatively low cut-to-land ratio may be preferred if the perforation and / or score path does not traverse a portion of the closure gusset. For example, the cut to land ratio can be from about 0.7:1 to about 6:1, or from about 1:1 to about 5:1, or from about 2:1 to about 4:1, specifically reciting all values ​​within these ranges, and any ranges formed within or formed by these ranges.

[0097] The package of the present disclosure may include a weakened area, which is disposed on a portion of the upper edge area of ​​the package only between the top panel and the front panel, or only between the top panel and the rear panel. Such a weakened area configuration may be beneficial when the article is disposed in a tri-fold configuration within the interior compartment of the package, with the fold tips disposed adjacent to the first and second side panels of the package. In such a configuration, the weakened area may form a peripheral opening slit the same size as the article, allowing only one article at a time to pass through the opening, thus allowing the remaining articles to remain tightly and regularly held within the package.

[0098] The packages of the present disclosure may include a weakened region disposed on a portion of the upper edge region of the package only between two contiguous panels, such as the top panel and the front and side panels, or the rear and side panels.

[0099] The package of the present disclosure may include a weakened area disposed on a portion of the upper edge region of the package only between the top panel and three consecutive panels, such as the front panel and two side panels, the rear panel and two side panels, or one of the side panels and both the front panel and the rear panel. In such a configuration, the weakened area may leave one side of the top panel attached to the remainder of the package, thus forming an opening that forms a hinge. Thus, the top panel may be removed from above the interior compartment to allow access to all of the items disposed within the package, but the top panel remains attached to the package and therefore easily accommodates replacement of the items.

[0100] The packages of the present disclosure may include a weakened area disposed on a portion of the top edge region of the package between the top panel and the front, back, and both side panels. In such a configuration, the top panel may be fully removable. Such a configuration may create a large opening to allow easy access to the interior compartment and the articles disposed therein.

[0101] 14A and 14B, the package 1 of the present disclosure may include a weakened area 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 rear panel 15, and at least a portion of one of the first or second side panels 12, 13. The weakened area may surround the closure gusset 11b. The weakened area may form an opening upon application of an appropriate force from a consumer that may remove the closure gusset 11b. Removal of the closure gusset may form an entry point to an interior compartment of the package approximately as wide as a side of the package. Such an entry point may provide for easy removal of an article located from the left or right side within the package. The weakened regions may include perforations and / or scores having a cut-to-land ratio of about 0.7:1 to about 6:1, or about 1:1 to about 5:1, or about 2:1 to about 4:1, specifically reciting all values ​​within these ranges, and any ranges formed within or formed by these ranges.

[0102] FIG. 15A is a perspective view of a package 1 of the present disclosure including a weakened region 700 disposed on at least a portion of at least three panels of the package. FIG. 15B shows the package of FIG. 15A in an opened configuration. With reference to FIG. 15A, the weakened region may include a series of perforations and / or scores 704 disposed on a portion of each of the at least three panels. The weakened region 700 may include a single path of perforations and / or scores 704 disposed along each of the panels, or, as discussed with respect to FIGS. 9A-9E, the weakened region may include multiple paths of perforations and / or scores 704 separated by aligned land areas 62. The aligned land areas may be disposed in transition areas between panels of the package, such as at package corners. The weakened area 700 may be disposed on at least three of the front 14, rear 15, first side 12, and second side 13 panels such that the weakened area 700 defines a base 1502 and a hood structure 1504 of the package. Referring now to FIG. 15B, it is believed that a hood 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 top panel 11, may provide an effective and easy to use cover for a supply of unused absorbent articles disposed within the package and may help protect against the ingress of airborne contaminants into the package. The hood structure 1504 is formed when a consumer tears the packaging material along the weakened area 700. If the weakened area is disposed on only three panels, a portion of the hood structure may be partially removable from the base, since at least one panel may remain intact and be attached to the base. After opening, the hood structure 1504 can be reopened by returning it to a position similar to the one it occupied relative to the rest of the package before opening.

[0103] As shown in Figures 15A and 15B, the weakened area 700 may include a path or paths of perforations and / or scores 704 disposed on a portion of both the first or second side panels 12, 13 and the front and back panels 14, 15. This configuration (designated herein as a "long-short-long" or "LSL" path) creates an opening along the entire short side (either the first or second side) of the package. Such a configuration may 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 may be exposed upon opening of the package and the article may be easy to remove. The perforation and / or score path may not traverse the full width of the front and / or back panels. For example, the perforation and / or score path may traverse about 25 percent, about 33 percent, about 45 percent, about 50 percent, about 60 percent, or about 75 percent of the width of the front and rear panels. Referring again to Figures 15A and 15B, if the perforation and / or score 704 path does not traverse the entire width of the front and / or rear panels, it may be beneficial for the stress distribution feature 69 to be disposed proximate to the end of the perforation and / or score 704 path. As discussed, the stress distribution feature may help to distribute concentrated tear stresses at the end and may help to reduce or prevent tearing of the packaging material beyond the end of the perforation and / or score path. In another example, the perforation and / or score path traverses the entire width of the front and rear panels.

[0104] In another form shown in FIG. 16, the weakened area 700 may include a path or paths of perforations and / or scores 704 disposed on one of the front or back panels 14, 15 and on a portion of both the first and second side panels 12, 13. This configuration (designated herein as a "short-long-short" or "SLS" path) is designed to form an opening along the entire long side (either the front or back) of the package. Such a configuration may be particularly useful when articles are stacked within the package from the front panel to the back panel. In such a case, the full width of the article may be exposed upon opening of the package and the article may be easy to remove. The perforation and / or score path traverses the entire width of the side panel. In another form, the perforation and / or score path may not traverse the entire width of the side panel. For example, the perforation and / or score path may traverse about 25 percent, about 33 percent, about 45 percent, about 50 percent, about 60 percent, or about 75 percent of the width of the side panel. The weakened region 700 may include a stress distribution feature disposed proximate the endpoints of the perforation and / or score path, as discussed with respect to FIG.

[0105] In one form, the weakened areas may be disposed on each of the front, rear, first side, and second side panels. The weakened areas may include a path or paths of perforations and / or scores across each of the panels. In such a configuration, the hood structure may be completely removable from the base. Such a configuration may be beneficial when the packaging material has limited flexibility and is prone to tearing.

[0106] 15A, 15B, and 16, weakened regions 700 can be disposed on at least three panels of package 1 such that base 1502 has a base height (BH) and hood structure 1504 has a hood height (HH). Additionally, the base height can be about 60 percent to about 90 percent, about 65 percent to about 85 percent, or about 70 percent to about 85 percent of the total height of the package, specifically reciting all values ​​within these ranges, and any ranges within or formed by these ranges.

[0107] It is believed that consumers may prefer a hood structure that has at least a minimal amount of material to grip and pull back the unused portion of the absorbent article in the package. The minimal amount of material can be placed around a portion of the stack of absorbent articles in the package and remain in place until removed again by the user. Thus, the packages of the present disclosure may have a hood height (HH) of at least about 15 mm, at least about 20 mm, or at least about 25 mm.

[0108] The packages of the present disclosure may be reclosable. The packages may include a means for reclosing the package after opening around one or more weakened areas. The means for reclosing may be, for example, a pressure sensitive adhesive, a reclosable zipper, and a hook and loop fastener. The means for reclosing the package may be disposed adjacent to one or more weakened areas.

[0109] The packages of the present disclosure may include two or more weakened areas. Each weakened area may include a path or paths of perforations and / or scores. The paths of perforations and / or scores may not intersect. The packages of the present disclosure include two or more weakened areas within the top 50% of the package height.

[0110] The packages of the present disclosure may include graphic indicia and / or a distinguishing color to alert a user to the presence of the weakened area. In one form, the weakened area may include a distinguishing color. The distinguishing color may be a different color than the color disposed on the consumer-facing panel of the package. The package may also, or instead, include a graphic representation, such as a graphic of a pair of scissors disposed adjacent to the weakened area. The inventors have found that placement of graphic indicia and / or a distinguishing color in the weakened area of ​​the packages of the present disclosure may increase consumer awareness and enjoyment of the weakened area configured to function as an opening mechanism.

[0111] Regardless of the configuration of the weakened area of ​​the package of the present disclosure, the package may have a weakened area tensile strength (WRTS) of at least 1.18 kN / m, or from about 1.18 kN / m to about 8.00 kN / m, from about 1.27 kN / m to about 6.50 kN / m, from about 1.35 kN / m to about 5.00 kN / m, from about 1.49 kN / m to about 4.72 kN / m, from about 1.49 kN / m to about 3.35 kN / m, or from about 1.6 kN / m to about 3.00 kN / m according to the strength tensile test method described herein, specifically reciting all values ​​within these ranges and any ranges formed within or by these ranges. It is believed that packages including weakened areas having a WRTS within the above ranges may be sufficient to withstand unintentional breakage during package formation, package filling, shipping, and store display.

[0112] The inventors have discovered that a package having a balance between the strength properties (tensile strength) of the package material in the non-weakened areas and the strength properties (WRTS) of the package material in the weakened areas can provide a flexible and resilient package that can withstand the rigors of the manufacturing process and also provide an opening mechanism configured for easy package opening. This balance can be calculated by taking the ratio of the weakened area tensile strength (WRTS) of the package to the tensile strength of a portion of the package without the weakened area (according to the strength pull test method), and is referred to herein as the "Weakened Area Performance Factor" (WRP Factor). The packages of the present disclosure may have a WRP factor of from about 0.14:1 to about 0.98:1, from about 0.15:1 to about 0.98:1, from about 0.16:1 to about 0.94:1, from about 0.18:1 to about 0.94:1, from about 0.19:1 to about 0.94:1, from about 0.2:1 to about 0.94:1, or from about 0.23:1 to about 0.6:1, specifically reciting all values ​​within these ranges, and any ranges formed within or formed by these ranges.

[0113] Table 2 presents the weakened area tensile strength (WRTS) data from a variety of sample packaging materials. WRTS and WRP modulus data from weakened area configurations, including perforation paths with different cut-to-land ratios and different perforation geometries, are presented for each packaging material. All weakened areas of the samples presented in Table 2 include straight perforations with a land area of ​​1 mm, except for the "angled perforation" variable. The "angled perforation" variable includes perforations shaped as shown in FIG. 7E, with a land area of ​​approximately 2.5 mm.

[0114] Sample 5 is a calendered specialty kraft packaging material made of fully virgin fibers having a basis weight of 70 gsm available from Mondi™ under the trade name Advantage Smooth White Strong. Various weakened area configurations are presented, including perforation paths located in the CD of the packaging material.

[0115] Sample 6 is a paper packaging material made from pure white kraft pulp and composed entirely of virgin fibers, having a basis weight of 70 gsm, available from BillerudKorsnas™. Various weakened area configurations are presented, including perforation paths located in the CD of the packaging material.

[0116] Sample 7 is a paper packaging material made from pure white kraft pulp and composed entirely of virgin fibers, having a basis weight of 80 gsm, available from BillerudKorsnas™ under the trade name Axello Tough White. Various weakened area configurations are presented, including perforation paths disposed in the CD of the packaging material.

[0117] [Table 2]

[0118] As shown in Table 2, the WRTS of packaging materials with various weakened area configurations range from 0.63 kN / m to 4.64 kN / m. The data suggests a trend for lower cut-to-land ratio configurations to exhibit higher tensile strength compared to higher cut-to-land ratio configurations. However, weakened areas including angled perforations do not follow this trend. The weakened area containing the angled perforations exhibited the lowest WRTS. The weakened area performance factor (WRP factor) data followed a similar trend to the WRTS data, with lower cut-to-land ratio configurations exhibiting higher WRP factor scores.

[0119] Table 3 presents the tear tensile data from Samples 5 and 7, as explained above. The absolute tear strength is the force required to tear the land area of ​​a single perforation within the land areas of the first five perforations of a weakened region when measured according to the tear tensile test method described herein. The relative tear strength is the average force required to tear a 1 mm land area over the land areas of the first five perforations of a weakened region when measured according to the tear tensile test method described herein. The data can be useful to determine perforation configurations and patterns that may be relatively easy for consumers to open.

[0120] [Table 3]

[0121] As shown in Table 3, the absolute tear strength range was 0.63N to 1.56N. The relative tear strength was slightly higher for Sample 5 compared to Sample 7. This is consistent with the WRTS data presented in Table 2, which indicates that the various weakened area configurations disposed in Sample 5 have slightly higher WRTS than the same configurations disposed in Sample 7. Without wishing to be bound by theory, it is believed that the higher WRTS and relative tear strength of Sample 5 compared to the same configurations in Sample 7 may be due to the packaging material of Sample 5 having a slightly higher MD tensile strength. The weakened area containing the angled perforations in Sample 7 failed to open five consecutive land areas in two replicates. During testing in these two replicates, the tear line veered from the path of the perforations into the packaging material without the perforations.

[0122] Regardless of the configuration of the weakened areas of the packages of the present disclosure, the weakened areas may have an absolute tear strength of about 0.63 N to about 1.56 N per single perforation land area, about 0.73 N to about 1.46 N per single perforation land area, or about 0.8 N to about 1.3 N per single perforation land area according to the tear tensile test method described herein.

[0123] The packages of the present disclosure may include weakened regions having a relative tear strength of about 0.8 N / mm to about 1.3 N / mm, about 0.9 N / mm to 1.2 N / mm, or about 0.95 N / mm to about 1.15 N / mm according to the tear tensile test methods described herein.

[0124] The inventors have found, without wishing to be bound by theory, that process reliability for high speed commercial scale packaging equipment and acceptable weakened area openability can be simultaneously achieved by properly balancing the weakened area tensile strength (WRTS) and the tear strength of the weakened area. A proper balance of these parameters can provide a package that can withstand the rigors of the manufacturing process while also providing an opening mechanism configured to be easily opened by the consumer with minimal disruption to non-weakened areas of the package. This balance can be expressed by a tear performance (TP) factor. The TP factor is defined as the ratio of the package weakened area tensile strength (WRTS), according to the strength tensile test method described herein, to the absolute tear strength of the weakened area of ​​the package, according to the tear tensile test method described herein. The packages of the present disclosure may have a TP factor of about 0.8 to about 5, about 0.9 to about 4.5, or about 1 to about 4, specifically reciting all values ​​within these ranges and any ranges formed within or by these ranges. Packages having TP moduli within the above ranges are believed to exhibit sufficient strength to withstand the manufacturing process while being easily openable around the weakened areas with minimal disruption to the non-weakened areas of the package.

[0125] Test Method Tensile strength test method The strength tensile test method is performed in accordance with 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 specimens are cut from packaging material containing a weakened area. The first set of specimens contains a weakened area such that the weakened area is disposed across the test sample width and is centered along and perpendicular to the length of the specimen. The second set of specimens is cut from the same packaging material and oriented in the same direction as the first set, but does not contain a weakened area. The length of the specimen is approximately 101.6 mm (4 inches), allowing the specimens to be clamped in the instrument grips with a distance between the grips of 50.8 mm (2 inches). The grip separation speed during testing is 300 mm / min. When the specimens containing the weakened area are placed in the grips for testing, the path of the weakened area is centered between the grips and perpendicular to the tensile axis of the tensile tester. The average tensile strength of the first set of specimens containing the weakened area is reported to the nearest 0.01 kN / m as the Weakened Area Tensile Strength (WRTS). The average tensile strength of the second set of specimens without the weakened area is reported to the nearest 0.01 kN / m as the Package Tensile Strength (MD or CD).

[0126] Weakened Area Performance (WRP) Factor - The Weakened Area Performance Factor is calculated by taking the ratio of the Weakened Area Tensile Strength (WRTS) of the package to the tensile strength of the package measured in the same direction (MD or CD). The factor is calculated according to the following formula and is reported to the nearest 0.01:

[0128] Tear and Tensile Test Method The tear tensile test method is adapted for testing natural materials and packaging materials containing weakened areas, with the following specifications and / or modifications: the test specimen is cut from the packaging material containing the weakened area so that the path of the weakened area is oriented along the center of the test specimen width, in accordance with ASTM D2261-13, "Tearing Strength of Fabrics by the Tongue (Single Rip) Procedure (Constant-Rate-of-Extension Tensile Testing Method"). The test specimens are run in accordance with the ASTM D685-17 "Standard Practice of Conditioning Paper and Paper Products for Testing". The width of the specimen is 50.4 mm (2 in) with 25.4 mm (1 in) on either side of the line of the weakened area. The 75 mm (3 in) pre-notch made along the center of the width should not partially cut through the land area within the weakened area so that only the entire land area is torn during the test. A total of five replicate specimens are prepared. The distance between the clamps is set to 50.4 mm (2 in) at the start of the test and a test speed of 300 mm / min is used. Preconditioning, conditioning, and testing of the dry specimens are performed as specified in ASTM D685-17 "Standard Practice of Conditioning Paper and Paper Products for Testing". Using calculation option 1, average of the five highest peaks, measure the average tear strength (peak force) of each of the first five land areas torn during the test and record to the nearest 0.01 N. This procedure is repeated for all five specimens and the arithmetic mean of the five recorded values ​​is calculated and recorded to the nearest 0.01 N as the absolute tear strength value.

[0134] Bursting Strength Test Method Burst strength is the maximum uniformly distributed pressure that the test sample can withstand. Burst strength is measured according to compendial method ISO 2758 using a test apparatus as described within the method. A suitable instrument is the 13-60 Burst Tester for Paper and Foils, available from Testing Machines, Inc. (New Castle, DE), or equivalent. The instrument is calibrated and operated according to the manufacturer's instructions. All measurements are performed in a laboratory maintained at 23° C. + / - 2° C. and 50% + / - 2% relative humidity, with the test sample conditioned in this environment for at least 2 hours prior to testing.

[0135] Measurements are made on test samples taken from rolls or sheets of raw material, or on specimens taken from the finished package. When the test samples are cut from the finished package, care is taken not to contaminate or deform the test sample in 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 that does not contain folds, creases, or seams.

[0136] Measure the burst strength (using sufficient clamp pressure to prevent slippage during testing, and a pump flow rate of 95±15 mL / min) for a total of 10 replicate test specimens. For double-sided specimens, the side of the test specimen meant to face the inside of the package faces the pressure when placed in the clamp, and test 10 replicates in this orientation. For balanced (not offset) specimens, test 5 replicates with the inside of the package facing the pressure, and test 5 replicates with the outside of the package facing the pressure, and average the results together. Record the pressure at which each test specimen bursts to the nearest 0.001 kPa. If the burst pressure is less than 70 kPa, multiple layers of the test material should be used. Divide the burst pressure by the number of layers tested to obtain the burst strength. Calculate the arithmetic mean burst pressure of all replicates and report as the burst strength to the nearest 0.001 kPa.

[0137] Caliper Test Method The caliper or thickness of single layer test specimens is measured by micrometer under static load according to compendial method ISO 534, with the modifications described herein. All measurements are performed in a laboratory maintained at 23°C ± 2°C and 50% ± 2% relative humidity, and the test specimens are conditioned in this environment for at least 2 hours prior to testing.

[0138] Caliper is measured with a micrometer equipped with a foot press capable of applying a constant pressure of 70 kPa ± 0.05 kPa to the test sample. The micrometer is a deadweight instrument that is accurate to 0.1 micrometers. A suitable instrument is a TMI Digital Micrometer Model 49-56, available from Testing Machines Inc., New Castle, Del., or equivalent. The foot press is a flat, grounded, circular, movable surface that has a diameter smaller than the test specimen and is capable of applying the required pressure. A suitable foot press has a diameter of 16.0 mm. The test sample is supported by a horizontal, flat reference platform that is larger than and parallel to the surface of the foot press. The system is calibrated and operated according to the manufacturer's instructions.

[0139] Measurements are made on single layer test samples taken from rolls or sheets of raw material, or on test samples taken from the finished package. When the test samples are cut from the finished package, care is taken not to contaminate or deform the sample in the process. The cut sample must be free of residual adhesive and must be taken from an area of ​​the package that is free of seams or folds. The test sample should ideally be 200mm long. 2 and must be larger than the presser foot.

[0140] To measure the caliper, first zero the micrometer against a horizontal flat reference platform. Place the test specimen on the platform with the test location centered under the footpressor. Gently lower the footpressor at a downward speed of 3.0 mm / sec until full pressure is applied to the test specimen. After waiting 5 seconds, record the caliper of the test specimen to the nearest 0.1 micrometer. Repeat in the same manner for a total of 10 replicate test specimens. Calculate the arithmetic mean of all caliper measurements and report this value as the caliper to the nearest 0.1 micrometer.

[0141] Basis Weight Test Method The basis weight of a test sample is the mass in grams per unit area in square meters of a single layer of material and is measured according to compendial method ISO 536. A block of test sample is cut to a known area and the mass of the sample is measured using an analytical balance accurate to 0.0001 grams. All measurements are performed in a laboratory maintained at 23°C ± 2°C and 50% ± 2% relative humidity, and the test sample is conditioned in this environment for at least 2 hours prior to testing.

[0142] Measurements are made on test samples taken from rolls or sheets of raw material or from finished packages. When cutting test samples from finished packages, care is taken not to contaminate or deform the samples in the process. Cut samples should be free of residual adhesive and should be taken from areas of the package that are free of seams or creases. Test samples should be as large as possible to account for any inherent material variations.

[0143] Measure the dimensions of the single layer test specimen using a NIST traceable calibrated steel metal ruler or equivalent. Calculate the area of ​​the test specimen and record to the nearest 0.0001 square meter. Obtain the mass of the test specimen using an analytical balance and record to the nearest 0.0001 gram. Calculate the basis weight by dividing the mass (in grams) by the area (in square meters) and record to the nearest 0.01 grams per square meter (gsm). Repeat in the same manner for a total of 10 replicate test specimens. Calculate the arithmetic average of the basis weights and report to the nearest 0.01 grams per square meter.

[0144] Bag stacking height test method The stack height of a package of absorbent articles within a bag is measured as follows.

[0145] device A thickness tester is used that has a flat rigid horizontal sliding plate. The thickness tester is configured such that the horizontal sliding plate is free to move vertically while always maintaining a horizontal orientation just above a flat rigid horizontal base plate. The thickness tester includes a device suitable for measuring the gap between the horizontal sliding plate and the horizontal base plate to within ±0.5 mm. The horizontal sliding plate and the horizontal base plate are larger than the surface of the absorbent article package that contacts each plate (i.e., each plate extends beyond the contact surface of the absorbent article package in all directions). The horizontal sliding plate exerts a downward force of 850±1 grams force (8.34 N) on the absorbent article package, which may be achieved by placing a suitable weight in the center of the top surface of the horizontal sliding plate that does not contact the package, such that the total mass of the sliding plate plus the additional weight is 850±1 grams.

[0146] Test procedure The absorbent article packages are equilibrated at 23±2° C. and 50±5% relative humidity prior to measurement.

[0147] Raise the horizontal sliding plate and center the absorbent article package under the horizontal sliding plate with the absorbent articles in the package in a horizontal orientation (see Figure 6). Any handles or other packaging mechanisms on the surface of the package that would contact any of the plates are folded flat against the surface of the package to minimize their effect on the measurement. Slowly lower the horizontal sliding plate until it touches the top surface of the package and then release it. 10 seconds after releasing the horizontal sliding plate, measure the gap between the horizontal plates to within ±0.5mm. Measure five identical packages (same size package and same number of absorbent articles) and record the arithmetic mean as the package width. Calculate "in-bag stack height" = (package width / number of absorbent articles per stack) x 10 and report within ±0.5mm.
