ゴミとなるので環境上好ましくない。However, since the heat-shrinkable film sheet used in the packaging apparatus 1 is made of an anisotropic material due to heat shrinkage, the heat-shrinkable film sheet is likely to be torn off the perforations 4 and torn. The strip-shaped portion 5a to be broken may be broken in the middle. In such a case, it is difficult to break the film sheet 5 along the perforations 4 again, and the strip-shaped portion 5a cut off in the middle becomes scattered dust, which is not environmentally preferable.

A packaging device 1 in which a separate opening tape 8 is attached from the back side of the film sheet 5 has also been proposed. In this case, since the film sheet 5 is torn by pulling the opening tape 8 together with the film sheet 5 as a reinforcing material, the packaging device 1 can be easily opened.

Since it is separated from the apparatus 1, it is liable to be scattered dust, which is environmentally unfavorable. Furthermore, since the opened packaging device 1 is in a state where only the strip portion 5a of the film sheet 5 has been removed and the remaining portion still covers the container 9, it is necessary to remove the remaining portion from the container 9. It is.

As shown in (c), near the side edge 31a of the joining band 31 farther from the fold line 34, the starting end 35a and the end 3
A plurality of perforations 35 having a predetermined length D up to 5b are formed discontinuously across a predetermined width L in the longitudinal direction. In order to cut the perforation 35, a perforation jig 36 having a tooth shape of a predetermined length D is used.
This is performed using The perforations 35 function as opening guidance means for opening the film sheet. Here, since the tubular member 32 is folded parallel to the joining band 31 at the fold line 34, two perforations 35 are formed simultaneously by cutting one perforation 35. Thereby, the adjustment of the predetermined width L between the perforations 35 is easy.
