ガゼツト袋。[Claims for Utility Model Registration] Consisting of a cylindrical molded body of multilayer plastic film having a heat-welding layer on the inside and a non-thermal welding layer on the outside, the product is folded inward by attaching a gusset to the non-thermal welding to each other. a first folding surface portion and a second folding surface portion that are connected via a fold so that the layers face each other, and a first folding surface portion such that the heat welding layer faces the heat welding layer of the first folding surface portion; The cylindrical molding includes: a front surface that is connected to the second folding surface through the fold; and a rear surface that is continuous to the second folding surface through the fold such that the heat welding layer faces the heat welding layer of the second folding surface. In a gusset bag in which a predetermined heat-sealed portion in a direction transverse to the body is heated to heat-seal the heat-welding layers facing each other, the heat-sealed portions of the first folding surface portion and the second folding surface portion are heat-sealed. A cutout part is formed in a part, and the heat welding layer of the heat sealing part of the front part and the heat welding layer of the heat sealing part of the rear part are thermally welded through the cutout part.
Gazette bag.
