2. Description of the Related Art Conventionally, a pillow-type easy-open packaging bag for opening a bag by diagonally tearing the bag in the direction from the joint heat bonding portion to the edge heat bonding portion is described in Japanese Utility Model Laid-Open No. 62-12060. A tape made of a uniaxially stretched film is adhered along an expected tear line including an edge portion of a sealing surface of the sealing packaging bag, and at least one tear notch is provided at an edge where the sealing surface and the film overlap. There is known a configuration in which a tearing line of a gusset type gaspable sticking bag is formed so as to form an elevation angle from an edge of the gasket sticking surface toward a side portion of the bag. . However, in the case of the bag having the above configuration, a step of adhering a tape made of a uniaxially stretched film is required along a scheduled tear line including a sealing surface edge of the sealing packaging bag. In this case, there is a disadvantage in that the step of adhering a tape made of a uniaxially stretched film to the surface of the bag becomes extremely complicated, and it becomes difficult to increase the production efficiency, resulting in an increase in cost. Further, there is a disadvantage that the tape made of the uniaxially stretched film may not be torn along the tape unless the tape is strongly adhered to the surface of the bag so as not to peel off.

A pillow-type bag comprising a laminated body having a base material layer and a thermo-adhesive resin layer and formed by a thermo-adhesive portion and an edge thermo-adhesive portion. An opening start portion is provided, and a cut line extending obliquely from the opening start portion toward both side ends of the bag is formed so as to penetrate at least the base material layer of the laminate, thereby forming a joint thermal bonding. Since the back opening side of the bag can be torn diagonally from the opening start portion toward both side edges from the opening start portion, a large triangular opening having the opening start portion as a vertex can be formed.
The contents can be easily taken out from the opening.

The details of the score line 4 formed in the laminate are shown in FIG.
As for the score line 4, the vicinity of the fold line 3a and the fold line 3b is a cut line non-formed portion 7a and a cut line non-formed portion 7b,
A scar group 8a and a scar group 8b are formed in an area inside the edge of the score line 4 that starts tearing from the score line non-formed portion 7a and the score line non-formed portion 7b. By forming the scar group 8a and the scar group 8b as shown in FIG. 4, after the tear reaches the score line non-formed portion 7a and the score line non-formed portion 7b, the cut edge 4 The tear line does not deviate from the score line 4 when tearing continuously. In the step of making a gusseted pillow-type bag using the laminate having the score line 4 shown in FIG. 3, the folds 3a and 3b for forming the folded portions on both sides of the bag are formed. Since the score line 4 is not formed in the vicinity, it is possible to prevent the laminate from tearing along the score line 4 when the laminate is bent at the folds 3a, 3b, and 3c to form a folded portion. .

If the heat-adhesive resin layer constituting the laminate can be made thin, it is preferable to form a score line penetrating the base material layer of the laminate, and the heat-adhesive resin layer constituting the laminate needs to be thicker In this case, it is preferable to form a score line penetrating the laminate. When the score line is formed in a state of penetrating the base material layer of the laminate or in a state of penetrating the laminate, the gas barrier property of the laminate is reduced, but the easily-openable packaging bag of the present invention is used for individually packed products. Since it is used as a bag for packaging, a slight decrease in gas barrier properties of the laminate does not pose a problem.

As the base material layer constituting the laminate of the embodiment, a biaxially oriented plastic film such as biaxially oriented polyethylene terephthalate, biaxially oriented polypropylene, or biaxially oriented nylon and pure white, imitation paper, woodfree paper, kraft paper And the like, and a polyolefin such as polyethylene, polypropylene and ethylene-vinyl acetate copolymer can be used as the heat-adhesive resin layer. When the base layer is formed by laminating a biaxially stretched plastic film and thin paper, the rigidity of the laminate is increased and the shape retention of the bag is excellent, so that an outer bag excellent in design can be obtained. Since the easy-open packaging bag of the present invention is used as an outer bag for stacking and packaging small bags individually wrapped with a gas barrier film, it has excellent gas barrier properties as a base layer constituting a laminate. There is no need to use film.
