Description

This invention relates to packaging for sanitary paper such as paper towels. For hygiene purposes, disposable paper products such as tissues and paper towels are widely used as sanitary paper. Furthermore, paper towels 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. Such sanitary paper is usually sold in plastic film packaging bags, but it has been proposed to use paper for the packaging bags (Patent Document 1 [0017]). Japanese Patent Publication No. 2003-104449 A figure showing one embodiment of the packaging of the present invention.An enlarged cross-sectional view of an example of crepe paper used to form the packaging bag shown in Figure 1.An enlarged cross-sectional view of another example of the crepe paper used to form the packaging bag in Figure 1. The present invention Sanitary paper, and, A packaging body comprising a packaging bag for containing the aforementioned sanitary paper, The present invention relates to a packaging body in which the aforementioned packaging bag is made of crepe paper. [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, cosmetic paper, etc.), 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). 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 cutting board liner; wiping dishes; wiping oil from frying pans; cleaning gas ranges and range hoods; and wiping dirt from dining tables. 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 possesses both water and oil absorption properties, making it suitable for use, for example, in a kitchen. The fibrous materials constituting sanitary 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. Wood pulp is preferred as the fibrous material constituting 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%). The basis weight of the sanitary paper is not particularly limited, but a basis weight (measurement method: JIS P 8124 [2011]) of 10 g/ m² to 100 g/ m² is preferred, and 30 g/ m² to 50 g/ m² is more preferred. Similarly, the paper thickness of the sanitary paper is not particularly limited, but 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 preferred. The sanitary paper used in this invention preferably has irregularities on one or both of its surfaces. These irregularities may be present on a portion of the surface of the sanitary paper, or on the entire surface. The uneven surface is preferably created by embossing. The height of the uneven surface (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. The form of the sanitary paper is not particularly limited; it may be in the form of a roll wound from a long sheet of paper. However, it is preferable that the sanitary paper be in a non-roll form, and more preferably 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 a single sheet (so-called 1-ply) folded in half, or in the form of a set of two (so-called 2-ply) or three (so-called 3-ply) or more laminated structures folded in half and used in the same way as a single sheet. It is preferable that the sanitary paper is contained in the packa
