[Package according to the present invention]
FIG. 1 is a perspective view showing an embodiment of a package according to the present invention. The packaging body 1 is configured by integrally packaging a plurality of packaging bodies 2 with a resin film 4. The resin film 4 is formed by bonding an opening tape 3 for cutting and separating the resin film 4 to the outside. And in the package 1, the opening tape 3 is formed so that it may go around the package 1 in a direction perpendicular to the stacking direction (X direction) of the plurality of packages 2. Thus, the user can easily cut and separate the resin film 4 from the portion of the opening tape 3 to open the packaging body 1 and easily take out the packaging bodies 2 one by one.

  The opening tape 3 that adheres to the outer side of the resin film 4, that is, the outer peripheral side including the packaged body 2 such as a plurality of rolls and cartons, when the user tries to take out a part of the packaged body 2, Since the resin film 4 functions so as to be easily and easily cut / separated along the opening tape 3, the opening tape 3 has a tensile strength of a predetermined value or more in the longitudinal direction. In the (width direction), a film made of a resin film having a tensile strength that is low enough to be torn by a predetermined tensile force is preferable.

  In addition, the resin film 4 has a predetermined tensile strength or more in the bonding direction of the opening tape 3 so that it can be easily cut and separated along the bonding direction of the opening tape 3, but in the direction perpendicular to the bonding direction. Those having a low tensile strength are preferred. Adhesion of the opening tape 3 to the resin film 4 is preferably made by intermittent heat fusion such as dot-like or perforated. In the case of continuous fusion, it is difficult to appropriately adjust the fusion force between the resin film 4 and the opening tape 3. That is, if the adhesive force between the resin film 4 and the opening tape 3 becomes too strong, the opening tape 3 is cut at the time of opening, while if too weak, only the opening tape 3 is detached and cannot be opened. As in the present invention, by intermittently heat-sealing, the opening tape 3 can be easily bonded without fine adjustment of the fusion power.

  Further, on the outer peripheral surface of the package 1, display is made by printing so that the end of the opening tape 3 can be clearly seen by the user, or a cut is inserted into the end of the opening tape 3. It is preferable to keep it.

  In the present invention, the material of the “resin film” is not particularly limited, and resins such as low-density polyethylene, unstretched polypropylene, high-density polyethylene, and stretched polypropylene that are usually used for packaging bags can be used. Among these, high-density polyethylene and stretched polypropylene are preferable in terms of stretchability and strength. These high-density polyethylene and stretched polypropylene are heat-shrinkable films. After the plurality of packages 3 are caramel-wrapped with the heat-shrinkable film, the films are heat-shrinked by heating, so that the packages 3 are appropriately disposed. Can be packaged. The thickness of the film varies depending on the type and weight of the packaged body, but when the tissue carton is to be packaged, the film thickness is preferably 10 to 35 μm. Further, gusset tubes are often used for packaging roll-like sanitary paper such as toilet paper. In this case, the thickness of the film is preferably 50 to 110 μm, and more preferably 65 to 90 μm.

  In the present invention, the material of the “opening tape” is not particularly limited, but the same material as the “resin film” can be used, such as low density polyethylene, unstretched polypropylene, high density polyethylene, stretched polypropylene, and the like. Resin can be used. Among these, high-density polyethylene and stretched polypropylene are preferable in terms of stretchability and strength. The opening tape may be the same material as the resin film, but may be a different material. As with the resin film, the thickness of the opening tape is preferably 10 to 35 μm when the tissue carton is to be packaged. In the case of packaging roll-like sanitary paper such as toilet paper, the thickness of the film is preferably 50 to 110 μm, more preferably 65 to 90 μm. The width of the opening tape is usually in the range of 0.5 to 5 mm, preferably 1 to 3 mm.

  There are no particular restrictions on the “packaged body”, but examples of the “packaged body” include disposable paper products, more specifically, roll-like sanitary paper (toilet paper, kitchen paper, towel paper, cooking sheets, etc.) ), Sanitary paper with cartons (such as tissue paper), sanitary napkins, disposable diapers, and the like.

[Manufacturing method of package]
FIG. 2 is explanatory drawing which shows one Example of the manufacturing method of the package which concerns on this invention. The resin film 11 is fed out from the roller 10 around which the resin film 11 is wound, and the opening tape 12 is synchronized with the feeding speed of the resin film 11 from the roller 13 around which the opening tape 12 is wound separately. Send out. Next, after the opening tape 12 is overlaid on the resin film 11, the resin film 11 and the opening tape 12 are sandwiched between a pair of heating rollers 14a and 14b, and intermittently heat-sealed in a dotted or perforated shape. By doing so, the resin film 15 with the tape for opening is obtained.
