Abstract (en)
A packaging bag (1) with zipper is provided, which enables easy identification whether or not the bag has been opened. For this purpose, in the packaging bag with zipper, the lower end portion of a male zipper tape (5) and the lower end portion of a female zipper tape (6) are bonded to the inner faces of respective front side (3) and rear side (4) sheet sections, or vice versa, along the opening end of the bag. The opening end comes at the top when the bag is in an upright state. The respective zipper tapes are bonded together at a position (9) below the engaging section (10) of the zipper tapes with heat sealing strength of a degree that allows the zipper tapes to be manual peeling apart, in such a manner that they may be manually peeled apart by an interface peeling action, an interlayer peeling action, or a cohesive peeling action. <IMAGE>
