Description

[Technical Field]

[0001] This invention relates to packaging for sanitary paper such as paper towels. [Background technology]

[0002] For hygiene purposes, disposable paper products such as tissues and paper towels are widely used as sanitary paper.

[0003] Furthermore, paper towels that are primarily used in the kitchen for purposes such as draining water and oil from meat, fish, and vegetables; as a cutting board mat; wiping dishes; wiping oil from frying pans; cleaning gas ranges and range hoods; and wiping up spills on the dining table are also called kitchen paper (including cooking paper) and are well known as a type of household paper.

[0004] Such sanitary paper is usually sold in packaging bags made of plastic film, but it has been proposed to use paper to make the packaging bags (Patent Document 1

[0017] ). [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2003-104449 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, ordinary paper packaging bags have poor elasticity, making them prone to tearing when external force is applied.

[0007] The present invention aims to provide a sanitary paper packaging that suppresses tearing of the packaging bag, even when using a paper packaging bag. [Means for solving the problem]

[0008] As a result of intensive studies, the inventors have found that by using a packaging bag made of crepe paper, breakage of the packaging bag is suppressed, and thus completed the present invention.

[0009] The present invention relates to toilet paper, and a packaging bag for containing the toilet paper and is a package comprising the packaging bag being made of crepe paper.

[0010] The thickness of the crepe paper is preferably 50 μm to 300 μm.

[0011] It is preferable that a thermoplastic resin layer exists on the surface of the crepe paper.

[0012] The thickness of the thermoplastic resin layer is preferably 10 μm to 30 μm.

[0013] The thermoplastic resin layer preferably contains a polyolefin.

[0014] The polyolefin is preferably a homopolymer or copolymer of ethylene.

[0015] The copolymer of ethylene is preferably a copolymer of ethylene and propylene and / or an α-olefin.

[0016] The thermoplastic resin layer preferably contains a thermoplastic resin having a melting temperature of 80° C. or higher measured according to JIS K7121.

[0017] It is preferable that the packaging bag consists only of the crepe paper and the thermoplastic resin layer.

[0018] The thermoplastic resin layer is preferably an extrusion coating layer.

[0019] It is preferable that the crepe paper forms the outer surface of the packaging bag.

[0020] It is preferable that the packaging bag is heat-sealed.

[0021] It is preferable that the packaging bag has at least one air vent.

[0022] It is preferable that the sanitary paper is contained in the packaging bag in a pop-up manner.

[0023] It is preferable that the aforementioned sanitary paper is a paper towel. [Effects of the Invention]

[0024] Although the present invention uses a paper packaging bag, the use of crepe paper as the paper increases the elasticity of the packaging bag and improves its ability to follow deformations against external forces, thereby suppressing tearing of the packaging bag.

[0025] If a thermoplastic resin layer is present on the surface of the crepe paper, heat sealing can be performed using this thermoplastic resin layer, making it easier to manufacture packaging bags.

[0026] Since the packaging of the present invention uses a paper packaging bag, it can better address environmental problems such as environmental pollution caused by the residual plastic in the environment when discarded, compared to using a plastic film packaging bag.

[0027] In particular, the crepe paper that makes up the packaging bag is originally an organic material derived from plants and is a carbon-neutral renewable resource, thus reducing the burden on the environment. Therefore, the packaging of the present invention is environmentally friendly. [Brief explanation of the drawing]

[Figure 2] An enlarged cross-sectional view of an example of crepe paper used to form a packaging bag in Figure 1. [Figure 3]An enlarged cross-sectional view of another example of the crepe paper used to form the packaging bag in Figure 1. [Modes for carrying out the invention]

[0029] The present invention Sanitary paper, and, Packaging bag for containing the aforementioned sanitary paper A packaging body equipped with, The present invention relates to a packaging body in which the aforementioned packaging bag is made of crepe paper.

[0030] [Sanitary paper] The packaging of the present invention includes sanitary paper. Sanitary paper is paper used for the purpose of improving hygiene, and examples include disposable papers such as tissue paper (also called face wipes or cosmetic paper), toilet paper, paper towels (kitchen paper, etc.), toilet paper, and wadding (paper cotton) (see, for example, the Paper and Pulp Technology Handbook, 5th edition, page 459, published January 30, 1992, edited and published by the Japan Paper and Pulp Technology Association). Sanitary paper is also called sanitary paper (JIS P0001:1998).

[0031] In this invention, paper towels such as kitchen paper are preferred as sanitary paper. Kitchen paper (including cooking paper) is mainly used in the kitchen for purposes such as draining water and oil from meat, fish, and vegetables; as a placemat for cutting boards; wiping dishes; wiping oil from frying pans; cleaning gas ranges and range hoods; and wiping dirt from dining tables.

[0032] Sanitary paper is porous and has the ability to absorb liquids. Examples of liquids include water and oil. Therefore, the sanitary paper used in this invention has water and oil absorbency and is suitable for use in kitchens, for example.

[0033] The fibrous materials that make up sanitary paper are not particularly limited, and examples include natural fibers such as cotton, wood pulp, and wool, regenerated fibers such as rayon, and synthetic fibers made from synthetic polymers such as vinylon, nylon, polyester, polyethylene, polypropylene, and acrylic. These fibers may be used individually or mixed and compounded. Wood pulp is preferred as the fibrous material that makes up sanitary paper, and virgin wood pulp, recycled paper pulp, or mixtures thereof can be used. As for wood pulp, for example, softwood pulp such as NBKP (bleached softwood kraft pulp) and NUKP (unbleached softwood pulp), and hardwood pulp such as LBKP (bleached hardwood kraft pulp) and LUKP (unbleached hardwood pulp) can be used individually or mixed in appropriate ratios. For example, the ratio of softwood pulp to hardwood pulp can be 1 (25%):3 (75%) to 1 (50%):1 (50%).

[0034] While there are no specific limitations on the basis weight of sanitary paper, the basis weight (measurement method: JIS P 8124

[2011] ) is 10 g / m². 2 ~100g / m 2 Preferably, 30 g / m 2 ~50g / m 2 This is more preferable. Furthermore, while the paper thickness of the sanitary paper is not particularly limited, a paper thickness (measurement method: JIS P 8118

[2014] ) of 50 μm to 300 μm is preferred, and 80 μm to 200 μm is more preferable.

[0035] The sanitary paper used in this invention preferably has irregularities on one or both of its surfaces. The irregularities may be present on a part of the surface of the sanitary paper, or on the entire surface.

[0036] The unevenness is preferably created by embossing. The height of the unevenness (the vertical height from the bottom of the recess to the top of the protrusion) is not particularly limited, but for example, it may be 0.1 mm to 5 mm or 1 mm to 3 mm.

[0037] The form of the sanitary paper is not particularly limited, and it may be in the form of a roll wound from a long length of sanitary paper, but it is preferable that the sanitary paper be in a non-roll form, and it is even more preferable that a flat sheet of sanitary paper be folded and placed inside the packaging bag. The sanitary paper may be used in the form of one sheet (so-called 1-ply) folded in half, or in the form of a set of two sheets (so-called 2-ply) or three or more sheets (so-called 3-ply) of laminated structure folded in half and used in the same way as a single sheet.

[0038] It is preferable that the sanitary paper is contained in the packaging bag in a pop-up manner. With a pop-up manner, after removing one sanitary paper from the packaging bag, a portion of the next sanitary paper is exposed, making it easy to remove the next sanitary paper.

[0039] It is preferable that the sanitary paper used is not clothing such as diapers, adult incontinence pants, or infant training pants.

[0040] [Packaging bag] The packaging bag of the present invention is made of crepe paper. The shape of the packaging bag is not particularly limited and can be, for example, non-box-shaped or box-shaped.

[0041] The packaging bag of the present invention preferably has at least one air vent. The air vent has the function of expelling air from inside the packaging bag to the outside, and by expelling air from inside the packaging bag to the outside, the volume of the packaging bag can be reduced, for example, making it easier to pack the packaging bag.

[0042] Air holes can be formed, for example, by piercing crepe paper or a packaging bag made of crepe paper with at least one needle or the like.

[0043] The number of air holes is not particularly limited, but multiple holes are preferred, preferably 2 to 100 per packaging bag, and more preferably 10 to 50.

[0044] The (cross-sectional) shape of the air holes is not limited. For example, the shape of the air holes can be circular or non-circular, and an example of the shape of non-circular air holes is a short slit.

[0045] The spacing between the air holes is not particularly limited. For example, the spacing between the air holes can be in the range of 10 mm to 50 mm, preferably in the range of 15 mm to 40 mm, and more preferably in the range of 20 mm to 30 mm.

[0046] The installation density of the air holes is also not particularly limited. For example, the installation density of the air holes can be in the range of 1 to 10 per 25 cm 2 for the surface where the air holes are present, and preferably in the range of 2 to 8 per 25 cm 2 and more preferably in the range of 3 to 6 per 25 cm 2 for the surface where the air holes are present.

[0047] The distribution of the air holes can be uniform or non-uniform. For example, when the packaging bag is box-shaped, it is preferably formed on the side surface of the packaging bag.

[0048] A plurality of air holes may be arranged in a straight line to form one row or two or more rows of air hole rows. The spacing between the air hole rows is not limited, but for example, it can be a spacing of 5 mm to 50 mm, 10 mm to 40 mm, or 15 mm to 30 mm.

[0049] [Crepe paper] The packaging bag of the present invention is made of crepe paper. The number of crepe papers constituting the packaging bag of the present invention is not particularly limited, but the packaging paper of the present invention is preferably made of one crepe paper. Crepe paper has a large number of wrinkles, and therefore has excellent stretchability. Accordingly, the packaging bag of the present invention has high deformability. In particular, the packaging bag of the present invention is excellent in stretchability and has improved followability to deformation against external forces, so that breakage of the packaging bag can be suppressed.

[0050] The crepe paper constituting the packaging bag of the present invention is 20 g / m 2 ~100 g / m 2It has a basis weight (measurement method: JIS P 8124

[2011] ). The basis weight of crepe paper is 30 g / m². 2 ~75g / m 2 Preferably, 35 g / m 2 ~50g / m 2 This is preferable.

[0051] The paper thickness of the crepe paper used in this invention (measurement method: JIS P 8118

[2014] ) is preferably 50 μm to 300 μm, and more preferably 80 μm to 200 μm.

[0052] The fibrous materials that make up crepe paper are not particularly limited and can include natural fibers such as cotton, wood pulp, and wool; regenerated fibers such as rayon; and synthetic fibers made from synthetic polymers such as vinylon, nylon, polyester, polyethylene, polypropylene, and acrylic. These fibers may be used individually or mixed and compounded.

[0053] As the fibrous material constituting the crepe paper, wood pulp is preferred, and virgin wood pulp, recycled paper pulp, or mixtures thereof can be used. As wood pulp, for example, softwood pulp such as NBKP (bleached softwood kraft pulp) and NUKP (unbleached softwood pulp), hardwood pulp such as LBKP (bleached hardwood kraft pulp) and LUKP (unbleached hardwood pulp), and mixtures of softwood pulp and hardwood pulp can be used.

[0054] Crepe paper can be manufactured by conventionally known methods. For example, it can be manufactured by pressing wet paper onto the surface of a heated cylindrical Yankee dryer, allowing it to adhere, and then, after a certain period of drying, peeling the paper off the Yankee dryer via a doctor blade to perform the crepe process.

[0055] In this invention, by using crepe paper as the wrapping paper that constitutes the packaging bag, the contact points between the packaging bag and the sanitary paper are reduced, and thus the likelihood of the sanitary paper getting caught on the packaging bag is also suppressed. Therefore, the packaging of the present invention makes it easy to package the items to be packaged.

[0056] (thermoplastic resin layer) It is preferable that a thermoplastic resin layer is present on the surface of the crepe paper used in the present invention. The number of thermoplastic resin layers is not particularly limited, but it is preferable that there be one or two thermoplastic resin layers, and that they are present on one surface of the crepe paper. By limiting the thermoplastic resin layers on the crepe paper to one or two, the combined thickness of the crepe paper and the thermoplastic resin layers can be suppressed.

[0057] If a thermoplastic resin layer is present on the surface of the crepe paper used in this invention, packaging bags can be easily manufactured by melting the thermoplastic resin layer and heat-sealing it. The thermoplastic resin layer does not need to be present on the entire surface of the crepe paper; it is sufficient if it is present on at least a part of the surface (e.g., the edges), but it may also be present on the entire surface of the crepe paper. Even if the thermoplastic resin layer is present on the entire surface of the crepe paper, the elasticity of the crepe paper can be maintained by appropriately selecting the type of thermoplastic resin, appropriately adjusting the thickness of the thermoplastic resin layer, etc.

[0058] The thermoplastic resin layer contains at least one type of thermoplastic resin. A single type of thermoplastic resin may be used, or multiple types of resins may be used in combination.

[0059] The type of thermoplastic resin is not particularly limited, and for example, polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamides such as nylon, polyvinyl chloride, polyvinylidene chloride, poly(meth)acrylate, etc. can be used. It is preferable that the thermoplastic resin contains polyolefin.

[0060] Polyolefins consist of at least one olefin having 2 to 10 carbon atoms. Two or more olefins may be used in combination. Specific examples of olefins include ethylene, propylene, and α-olefins.

[0061] Examples of polyolefins include ethylene homopolymers or copolymers, propylene homopolymers or copolymers, and butene homopolymers or copolymers. They may also be random copolymers or block copolymers of ethylene and propylene.

[0062] The polyolefin is preferably a homopolymer or copolymer of ethylene. The ethylene copolymer is preferably a copolymer of ethylene and propylene and / or an α-olefin, and more preferably a copolymer of ethylene and an α-olefin. The α-olefin includes those having 3 to 20 carbon atoms, preferably 3 to 8. Examples include 1-butene, 1-hexene, 4-methyl-1-pentene, 1-octene, vinylcyclohexane, etc., but 1-hexene is preferred. The polyolefin is particularly preferably a copolymer of ethylene and 1-hexene or a copolymer of ethylene, propylene, and 1-hexene.

[0063] Polyolefins synthesized using metallocene catalysts are preferred, and those synthesized by the gas phase method are more preferred. Examples of polyolefins synthesized using metallocene catalysts include KF260T, KF270, KF271, KF282, KF283, KF360T, KF370, KF380, KC452T, KC570S, KC580S, KC573, KC577T, KS240T, KS340T, KS260, KS560T, KS571, and KJ640T, all manufactured by Nippon Polyethylene Co., Ltd. Examples of compounds synthesized by the gas phase method using metallocene catalysts include Harmolex NF324A, NF375B, NF366A, NF384A, NF444A, NF464A, NC564A, NF325N, NF464N, NF444N, NH645A, NH745N, NH845N, and NJ744N from Nippon Polyethylene Co., Ltd., and Evolu SP0510, SP1020, SP1520, SP1510, SP2020, and SP2320 from Prime Polymer Co., Ltd.

[0064] The thermoplastic resin layer preferably contains a thermoplastic resin having a melting temperature (measured by DSC method) of 80°C or higher as measured according to JIS K7121. It is more preferable that the thermoplastic resin contained in the thermoplastic resin layer consists only of a thermoplastic resin having a melting temperature (measured by DSC method) of 80°C or higher as measured according to JIS K7121. It is even more preferable that the thermoplastic resin having a melting temperature of 80°C or higher as measured according to JIS K7121 is the polyolefin. The melting temperature of the thermoplastic resin as measured according to JIS K7121 is more preferably 85°C or higher, even more preferably 90°C or higher, even more preferably 95°C or higher, and even more preferably 100°C or higher. The relatively high melting temperature of the thermoplastic resin can improve the tear strength of the packaging bag.

[0065] By using a crepe paper packaging bag equipped with a thermoplastic resin layer containing a thermoplastic resin with a melting temperature of 80°C or higher as measured according to JIS K7121, tearing of the packaging bag can be further suppressed. Therefore, the packaging body of the present invention can maintain the packaging of the packaged item in good condition.

[0066] The thickness of the thermoplastic resin layer is preferably 10 μm to 30 μm, more preferably 15 to 25 μm, and even more preferably 20 to 25 μm.

[0067] The thermoplastic resin layer may contain any additives. Examples of additives include various organic or inorganic fillers, tackifiers, antioxidants, anti-fogging agents, various organic or inorganic pigments, flame retardants, crosslinking agents, UV inhibitors, lubricants, and the like.

[0068] The crepe paper used in this invention may have layers other than the thermoplastic resin. For example, an arbitrary intermediate layer, such as an adhesive layer, can be provided between the crepe paper and the thermoplastic resin layer. Furthermore, an arbitrary layer, such as a protective layer, can be provided on the surface of the crepe paper opposite to the surface where the thermoplastic resin is present. However, in order to suppress the overall thickness and not impair the deformability of the crepe paper, it is preferable that the crepe paper consists only of a thermoplastic resin layer.

[0069] In the packaging of the present invention, it is preferable that crepe paper forms the outer surface of the packaging bag. This makes it easy to recognize that the packaging bag of the present invention is made of paper.

[0070] The method for manufacturing crepe paper having a thermoplastic resin layer is not particularly limited, and can be manufactured by methods such as integrating the crepe paper and the thermoplastic resin layer by extrusion lamination of the thermoplastic resin, or integrating a film made of thermoplastic resin and crepe paper with an adhesive. The method of integrating the crepe paper and the thermoplastic resin layer by extrusion lamination is preferred. That is, it is preferable that the thermoplastic resin is an extruded coating layer.

[0071] The combined thickness of the crepe paper and thermoplastic resin layer is preferably 50 μm to 300 μm, more preferably 60 μm to 200 μm, and even more preferably 70 μm to 100 μm.

[0072] [Manufacturing method for packaging] The method for manufacturing the packaging of the present invention is not particularly limited. For example, a flat crepe paper can be deformed into a bag shape with a storage compartment, sanitary paper can be placed in the storage compartment, and then the opening of the storage compartment can be sealed with an adhesive or the like to manufacture the packaging. If the crepe paper has a thermoplastic resin layer, the bag can be sealed by heat-sealing the opening of the storage compartment (which has a thermoplastic resin layer) to manufacture the packaging.

[0073] The heat sealing temperature depends on the type of thermoplastic resin contained in the thermoplastic resin layer, but is preferably 80°C to 350°C, more preferably 100°C to 300°C, and even more preferably 150°C to 250°C.

[0074] The heat sealing time also depends on the type of thermoplastic resin contained in the thermoplastic resin layer, but it is preferably 5 seconds or less, more preferably 3 seconds or less, and even more preferably 1 second or less.

[0075] [Example of packaging] Figure 1 shows one embodiment of the packaging of the present invention, where Figure 1(A) and Figure 1(B) show the front and back sides of one embodiment of the packaging of the present invention, respectively. Figure 1(C) is a cross-sectional view taken along line AA of Figure 1(A).

[0076] In Figure 1, 1 represents the packaging body, 2 is the packaging bag for the packaging body, and 3 is the sanitary paper contained in the storage compartment within the packaging bag 2.

[0077] The packaging bag 2 has multiple air holes 4, allowing air inside the packaging bag 2 to be released to the outside. By releasing the air inside the packaging bag 2 to the outside through the air holes 4, the volume of the packaging bag 2 can be reduced, making it easier to pack and transport the packaging bag 2, for example.

[0078] In the embodiment shown in Figure 1, a perforation 2-1 is formed on a part of the surface of the packaging bag 2, which allows an opening to be created for removing the sanitary paper 3. When removing the sanitary paper 3, the perforation 2-1 is torn to create an opening, and the sanitary paper 3 can be removed to the outside through this opening.

[0079] In the configuration shown in Figure 1, the sanitary paper sheets 3 are stacked in a so-called pop-up manner and stored inside the packaging bag 2. Therefore, when one sheet of sanitary paper sheet 3 is removed from the opening, a portion of the next sheet of sanitary paper sheet 3 can protrude from the opening, making it easy to remove the sanitary paper sheets 3.

[0080] Figure 2 is an enlarged cross-sectional view of an example of the crepe paper forming the packaging bag 2 in Figure 1. As shown in Figure 2, the crepe paper 5 has numerous wrinkles and excellent elasticity. Therefore, the packaging bag 2 made of crepe paper 5 has excellent elasticity, high deformation-following ability to withstand external forces, and is resistant to tearing.

[0081] Because sanitary paper is relatively prone to fraying, when a paper packaging bag comes into contact with it, the sanitary paper is likely to get caught in the packaging bag, making the packaging process difficult. However, in the example shown in Figure 2, the contact points between the crepe paper 5 and the sanitary paper 3 are limited to the raised areas of the crepe paper 5's wrinkles, thus reducing contact between the packaging bag 2 and the sanitary paper 3. Therefore, the sanitary paper 3 is less likely to get caught in the packaging bag 2, making the packaging of the sanitary paper 3 inside the packaging bag 2 easier.

[0082] The crepe paper 5 shown in Figure 2 has a thermoplastic resin layer at the edge (not shown), and a packaging bag can be formed by heat sealing this thermoplastic resin layer. By providing a thermoplastic resin layer, packaging bags can be easily manufactured by heat sealing.

[0083] Figure 3 is an enlarged cross-sectional view of another example of the crepe paper used to form the packaging bag 2 in Figure 1. In the example shown in Figure 3, the crepe paper 5-1 has a thermoplastic resin layer 5-2 covering the entire surface of one of its surfaces, making it laminated crepe paper. Therefore, in the example shown in Figure 3, the packaging paper 2 can be manufactured more easily by heat-sealing the thermoplastic resin layer 5-2 of the laminated crepe paper at any point. In addition, in the example shown in Figure 3, the thickness of the thermoplastic resin layer 5-2 is sufficiently thin, so the elasticity of the crepe paper 5-1 can be maintained.

[0084] The thickness of the laminated crepe paper (measurement method: JIS P 8118

[2014] ) is preferably 30 μm to 200 μm, and more preferably 70 μm to 150 μm.

[0085] The basis weight of the laminated crepe paper is 30 g / m². 2 ~120g / m 2 Preferably, 40 g / m 2 ~100g / m 2 This is preferable.

[0086] The density of the laminated crepe paper is 0.40 g / cm³. 3 ~1.00g / cm 3 Preferably, 0.50 g / cm³ 3~0.70g / cm 3 This is preferable.

[0087] In the example shown in Figure 3, the thermoplastic resin layer 5-2 faces the side of the sanitary paper 3 shown in Figure 1(C). Since the surface of the thermoplastic resin layer 5-2 is smooth, snagging of the sanitary paper 3 on the packaging bag 2 is suppressed. Therefore, even in the example shown in Figure 3, snagging of the sanitary paper 3 on the packaging bag 2 is suppressed, making it easy to package the sanitary paper 3 into the packaging bag 2.

[0088] In the packaging bag 2 shown in Figure 1, crepe paper forms its outer surface. Therefore, it is easy to recognize from the outside that the packaging bag 2 is made of paper. [Industrial applicability]

[0089] The packaging of the present invention uses a packaging bag made of stretchable crepe paper, which suppresses tearing of the packaging bag. Furthermore, it can suppress snagging of lint-prone sanitary paper on the packaging bag, making the packaging of the present invention suitable for packaging sanitary paper. [Explanation of symbols]
