When the sealant layer is laminated on the inner surface side of the laminated film sheet 10, the above-mentioned joining of the left and right side edge portions and the joining of the end edge portions can be realized by heating and pressurization, and the manufacturing efficiency is improved.

As the sheet forming the packaging bag of the present invention, a sheet having no sealant layer laminated on one side (inner side) can be used. As an example, a sheet mainly composed of paper may be used. In this case, an adhesive may be applied to the joining site.

Mainly referring to FIG. 6, the packaging bag 1 is provided with an opening guide 5. The unsealing guide 5 includes, as an example, a triangular notch 51 formed in the joining band 35 near the tip of the second sub-bag body 4. Instead of the notch 51, a cut 52 slightly cut in the joint band 36 may be used. In FIG. 6, for convenience of description, the joint band 35 is provided with a notch 51 and the joint band 36 is provided with a cut 52, but it is preferable that the actual packaging bag 1 is unified.

Further, the unsealing guide 5 may include a break line 53 indicating a break portion near the tip of the second sub-bag body 4.

The break line 53 does not continuously penetrate a short straight line or a small hole, but a short straight line or a small hole is continuously provided only on the surface of the laminated film so that the inside of the packaging bag does not come into contact with the outside air. (Providing a so-called half-cut structure) is preferable. The notch 51 may have a pentagonal shape like a shogi piece, instead of the triangular shape, and the triangular notch 51 is continuously formed so as to have a jagged shape on the entire left and right ends of the packaging bag 1. May be provided. Further, depending on the specifications of the manufacturing machine of the packaging bag 1, the opening guide 5 such as the notch 51, the cut 52, and the break line 53 is not limited to any one of the plurality of sub-bags, but to all the sub-bags. It may be provided. However, if the packaging bag 1 is opened with a plurality of sub-bags, the re-sealing function will not be provided. Therefore, when using it in a product, it should be clearly stated that there is only one opening. desirable.
