For example, it is preferable to form with a polyethylene resin such as low density polyethylene, a polypropylene resin, or a polyolefin resin such as a copolymer thereof. Examples of polypropylene resins include thermoplastic resins such as homopolypropylene, block polypropylene, random polypropylene (RPP), propylene-ethylene-butene 1 random terpolymer, and polyolefin special soft resin (TPO resin, such as prime polymer TPO). Alternatively, a mixture obtained by mixing these resins can be used.

  The material for forming the cut tape 4 is a resin that is different from and incompatible with the chuck tape 3 such as stretched polyethylene terephthalate (OPET), stretched polypropylene (OPP), stretched high-density polyethylene (HDPE), and the like. Formed with. For the cut tape 4, for example, an adhesive such as metallocene LL may be laminated and adhered to the laminated portion 36 of the chuck tape 3.

  In addition, when putting the content taken in by a human body, such as a foodstuff and a pharmaceutical, in the packaging bag 1, it is not preferable that a content touches an adhesive agent. In that case, the chuck tape 4 and the cut tape 3 may be fused by including the same kind of resin having a relatively low melting point. For example, polyethylene (PE) is used as a thermoplastic resin having a low melting point, the chuck tape 3 is made of polyethylene (PE), and the cut tape 4 is made of a mixture of polyethylene (PE) and polypropylene (PP). The cut tape 4 can be fused and laminated to the laminated portion 36 of the chuck tape 3 without using an agent. Specifically, (1) the chuck tape 3 extruded through the mold is cooled in the water tank, and (2) the cut tape 4 extruded through the mold is placed on the laminated portion 36 of the chuck tape 3 and cooled in the water tank.

The packaging bag 1 of the present invention is bent at the middle portion 37 of the male member 32 and the female member 33 of the chuck tape 3, and the surface including the laminated portion 36 of the belt-like base 31 is bonded to one surface of the bag body 2. ing. When enclosing the contents in the packaging bag 1, for example, a portion other than the portion where the chuck tape 3 is adhered to the film 2 a constituting the bag body 2 and the chuck tape 3 of 2 a and 2 b constituting the bag body 2 is adhered. The peripheral part is sealed with an adhesive such as polyester / isocyanate two-component liquid or means such as heat fusion, and after the contents are put into the packaging bag 1 from the opened part, the opened part is finally opened. What is necessary is just to seal by the means similar to the above. Moreover, as shown in FIG. 1, the tab 41 is formed in the end of the cut tape 4 by the notch which penetrates the bag body 2 and the strip | belt-shaped base part 31, for example by pressing a metal mold | die. When the tab 41 is pinched and pulled away from the bag body 2, the continuous cut tape 4 is separated from the tab 41, and with the separation of the cut tape 4, the stacked portion 36 and the bag body 2 are separated, and the packaging bag is separated. 1 can be opened. In addition, when enclosing the thing taken into the human body, such as food and a medicine, as the contents, the adhesion of the chuck tape 3 to the bag body 2 and the seal of the peripheral part of the packaging bag 1 are heat-sealed. It may be performed by.

  As for adhesion of the chuck tape 3 to the bag body 2, it is preferable that at least the laminated portion 36 and a portion adjacent to the laminated portion 36 are adhered to the bag body 2. If the adjacent portion is not bonded to the bag body 2, the incised bag body 2 is not only the portion that is bonded to the laminated portion 36, but also the bag body 2 portion that is not bonded to the laminated portion 36. However, the shape of the opening surface becomes unstable, which is not preferable. In the present invention, the “adjacent portion” means a portion necessary for stably separating the bag body 2 bonded to the laminated portion 36, for example, the embodiment shown in FIGS. 3 and 5. Then, the 1st thick part 34 and the 2nd thick part 35 are mentioned, and the same length as the lamination | stacking part 36 is mentioned in embodiment shown in FIG. Of course, it may be longer or shorter than the above length as long as the shape of cutting the bag body 2 is constant.
