As shown in FIGS. 4 and 5, the packaging film 30 is formed by winding a planar film into a substantially rectangular shape in the vertical cross-section in the front-rear direction so that openings 31 are formed on both sides in the left-right direction. The intermediate portion 33 of the overlapping portion 32 where the one side end and the other side end overlap each other is formed by performing a fusion process. As a result, the planar film is formed on the cylindrical body 34 and the tissue paper bundle 20 can be inserted into the cylindrical body 34 through the opening 31 formed on one side of the cylindrical body 34 . In addition, in the present embodiment, the overlapping portion 32 is wound so as to be positioned on the third surface 13 .

Note that pillow packaging is a form in which the ends of the upper portion 35A and the lower portion 35D of the extension portion 35 are superimposed and fusion-bonded to block the opening portion 31. As shown in FIG.

Similarly, the extending portion 37 of the tubular body 34 extending to the right side of the right portion of the tissue paper bundle 20 is folded into a caramel wrapping. That is, the upper side portion 37A of the extension portion 37 is bent downward, then the front side portion 37B and the rear side portion 37C are bent rearward and forward respectively, and then the lower side portion 37D is bent upward. The sixth surface 16 of the film-wrapped tissue 10 is formed by closing the opening 31 with a .

Specific examples of the flexible resin-made packaging film 30 constituting the exterior of the film-wrapped tissue 10 include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, and ethylene vinyl alcohol copolymer. Examples include a united single-layer film, an appropriately laminated laminate film containing these films, and a gas barrier film obtained by subjecting these films to surface treatment such as aluminum vapor deposition. Biomass films derived from plant materials such as sugarcane, potato (starch), and corn can also be used. The use of such biomass films is preferable from the viewpoint of environmental protection.
Polypropylene film and polyethylene film are suitable from the viewpoint of cost. Moreover, the packaging film 30 may be a satin-finished film that is excellent in design and touch. Furthermore, when packaging odorous items such as scented tissue paper, ethylene-vinyl alcohol copolymer resin film and polyethylene terephthalate resin film, which are excellent in scent retention, are preferable.

It is preferable that the thickness is 25 to 75 μm, and the softness measured based on the handle ometer method according to JIS L 1096 (2010) E method is 5.0 to 50.0 cN. If the thickness is 25 to 75 μm, the rigidity of the fifth surface 15 and the sixth surface 16 is sufficiently increased. In addition, with such thickness and softness, the packaging film 30 is less likely to tear, and the tissue paper can easily be taken out easily, particularly in popping up. In addition, the thickness was measured by sufficiently conditioning the humidity of the measurement sample under the conditions of JIS P 8111 (1998), and then using a dial thickness gauge (thickness measuring instrument) "PEACOCK G-1A type" (manufactured by Ozaki Seisakusho Co., Ltd.) or its equivalent.

The third surface 13 and the fourth surface 14 of the film-wrapped tissue 10 are opposed to 53 and the back surface 54, respectively, and the first film-wrapped tissue 10 is mounted to the left side 55 and the right side 56 of the film-wrapped tissue collective package 1, respectively. It is inserted so that the surface 11 and the second surface 12 face each other. As a result, when the film-wrapped tissue group package 1 is stacked on the upper side of the film-wrapped tissue group package 1, the compressive load acting on the sixth surface 16 of the film-wrapped tissue 10 is reduced to the sixth surface 16 having high rigidity. The tissue paper bundle 20 can be evenly distributed over the entire surface facing the tissue paper bundle 20 via the surface 16, and a plurality of film-wrapped tissue bundles 1 can be stacked on the upper side of the film-wrapped tissue bundle 1. .

The length between the first surface 11 of the tissue 10 and the second surface 12 of the film-wrapped tissue 10 located on the rightmost side is the length of the left side 55 and the right side 56 of the film-wrapped tissue collective package 1, that is, It is a value calculated by multiplying a value obtained by dividing by the length of the front surface 53 in the left-right direction by 100. FIG.

The length between the first surface 11 of the leftmost film-wrapped tissue 10 and the second surface 12 of the rightmost film-wrapped tissue 10 is the length between the first surface 11 and the second surface 12 of each film-wrapped tissue 10 . The length between the surfaces 12, that is, the length in the lateral direction of the third surface 13 was measured and totaled.

The length in the left-right direction of the third surface 13 of the film-wrapped tissue 10 was obtained by placing the film-wrapped tissue 10 on a surface plate with the first surface 11 facing upward, and measuring with a height gauge such as a dial gauge. . The length in the left-right direction of the front surface 53 of the film-wrapped tissue assembly package 1 was determined by measuring with a length gauge such as a vernier caliper.
