PACKAGING BAG WITH ZIPPER TAPE, DEVICE AND METHOD FOR MANUFACTURING PACKAGING BAG, AND BAND-LIKE MEMBER FOR BENDING

摘要

A packaging bag (1) includes a male belt-like base edge (214) and a female belt-like base edge (224) which are abutted on each other. Accordingly, a base material film (10) is bent between the male belt-like base edge (214) and the female belt-like base edge (224), thereby reliably engaging a male engagement portion (211) with a female engagement portion (221). According to a manufacturing device of the packaging bag, since a male belt-like member (21) and a female belt-like member (22) are bonded to a sheet of base material tape while the male belt-like base edge (214) and the female belt-like base edge (224) are substantially abutted on each other by first and second grooves, an adhesion operation can be conducted with accuracy.
