As shown in FIGS. 4 and 5, the packaging film 30 winds a flat film in a substantially rectangular shape in a vertical cross section in the front-rear direction so that openings 31 are formed on both sides in the left-right direction, and in the winding direction. It is formed by fusing the intermediate portion 33 in the overlapping portion 32 where the one side end portion and the other side end portion overlap. As a result, a flat film can be formed on the tubular body 34, and the tissue paper bundle 20 can be inserted into the tubular body 34 through the opening 31 formed on one side of the tubular body 34. In this embodiment, the superimposing portion 32 is wound so as to be located on the third surface 13.

That is, the upper portion 35A of the extending portion 35 is bent downward, then the front side portion 35B and the rear side portion 35C are bent to the rear side and the front side, respectively, and then the lower side portion 35D is bent upward. The fifth surface 15 of the film packaging tissue 10 is formed by the fusion treatment to close the opening 31. As a result, the fifth surface 15 formed by laminating four layers of the film as compared with the pillow packaging has higher rigidity, and the amount of displacement when a compressive load is applied to the fifth surface 15 can be suppressed. it can. The pillow packaging is a form in which the upper portion 35A of the extending portion 35 and the end portion of the lower portion 35D are overlapped and fused to close the opening 31.

Similarly, the extending portion 37 extending to the right side of the right portion of the tissue paper bundle 20 of the cylinder 34 is folded into a caramel package. That is, the upper portion 37A of the extending portion 37 is bent downward, then the front side portion 37B and the rear side portion 37C are bent to the rear side and the front side, respectively, and then the lower side portion 37D is bent upward. The sixth surface 16 of the film packaging tissue 10 is formed by closing the opening 31. As a result, the sixth surface 16 formed by laminating the film in four layers has higher rigidity than the pillow packaging, and the amount of displacement when a compressive load is applied to the sixth surface 16 can be suppressed. it can.

Specific examples of the flexible resin packaging film 30 constituting the exterior of the film packaging tissue 10 include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, and ethylene vinyl alcohol co-weight. Examples thereof include a combined single-layer film, an appropriately laminated laminated film containing those films, and a gas barrier film obtained by subjecting these films to a surface treatment such as aluminum vapor deposition. In addition, biomass films derived from plant raw materials such as sugar cane, potato (starch), and corn can also be used. The use of such a biomass film is preferable from the viewpoint of environmental protection.
From the viewpoint of cost, polypropylene film and polyethylene film are preferable. Further, the packaging film 30 may be a satin-finished film having excellent design and touch. Furthermore, when packaging odorous materials such as scented tissue paper, ethylene vinyl alcohol copolymer resin film and polyethylene terephthalate resin film, which have excellent aroma retention properties, are preferable. Even if it is a multi-layered resin film in which a polyethylene resin film or a polypropylene resin film is laminated on one or both sides of an ethylene vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film to improve heat-sealing properties.

The thickness is preferably 25 to 75 μm, and the softness measured based on the handle ometer method according to the JIS L 1096 (2010) E method is preferably 5.0 to 50.0 cN. When the thickness is 25 to 75 μm, the rigidity of the fifth surface 15 and the sixth surface 16 is sufficiently increased. Further, with such a thickness and softness, the packaging film 30 is not easily torn, and it is easy to make the tissue paper easy to take out, particularly to have excellent pop-up property. The thickness of the measurement sample was adjusted sufficiently under the conditions of JIS P 8111 (1998), and then the dial thickness gauge (thickness measuring instrument) "PEACOCK G-1A type" (manufactured by Ozaki Seisakusho Co., Ltd.) and its equivalent.

The compressibility of the first surface 11 and the second surface 12 of the film packaging tissue 10 in the normal direction is formed to be 80 to 100%, and preferably 85 to 90%. As a result, the proportion of voids in the tissue paper bundle 20 is reduced, and the rigidity of the film packaging tissue 10 against the compressive load acting in the normal direction of the first surface 11 and the second surface 12 is increased. Deformation can be suppressed.

If the compression ratio is less than 80%, the tissue paper bundle 20 may be excessively compressed in the normal direction of the first surface 11 and the second surface 12, and the softness of the tissue paper 21 may be reduced. If it exceeds 100%, the parallel posture of the tissue paper 21 of the tissue paper bundle 20 may be disturbed.

The normal compressibility of the first surface 11 and the second surface 12 of the film packaging tissue 10 is the length between the top surface of the tissue paper bundle 20 facing the first surface 11 and the bottom surface facing the second surface 12. A value calculated by multiplying the value obtained by dividing the length between the first surface 11 and the second surface 12 of the film packaging tissue 10, that is, the length in the vertical direction of the third surface 13, by 100. Is.

The length between the top surface of the tissue paper bundle 20 facing the first surface 11 and the bottom surface facing the second surface 12 was measured and determined as follows.

As a result, the parallel posture of the tissue paper 21 of the tissue paper bundle 20 may be disturbed.

The filling rate of the fifth surface 15 and the sixth surface 16 of the film packaging tissue 10 in the normal direction is between the left side surface facing the fifth surface 15 and the right side surface facing the sixth surface 16 of the tissue paper bundle 20. The length was calculated by multiplying the value obtained by dividing the length between the fifth surface 15 and the sixth surface 16 of the film packaging tissue 10, that is, the length of the third surface 13 in the left-right direction, by 100. The value.

The surface 11 and the second surface 12 are inserted so as to face each other. As a result, when the film packaging tissue assembly packaging 1 is stacked on the upper side of the film packaging tissue assembly packaging 1, the compressive load acting on the sixth surface 16 of the film packaging tissue 10 is applied to the sixth surface 16 having high rigidity. A plurality of film packaging tissue assembly packages 1 can be stacked on the upper side of the film packaging tissue assembly package 1 so that the tissue paper bundle 20 can be evenly distributed over the entire surface of the facing surfaces of the tissue paper bundle 20 via the surface 16. ..
