PACKAGING BAG WITH FASTENER TAPE

摘要

A belt-like base (331) of a female member (33) of a zipper tape (3) attached to inner surfaces of a bag body is widened toward a content side of the bag body relative to a facing belt-like base (321) of a male member (32) in order to define a seal base (36). The seal base (36) includes a wedge-shaped linear portion (35) formed in parallel to a longitudinal direction of an engagement portion (31). A seal portion (4) is formed adjacent to a content-side edge (35A) of the linear portion (35) by sealing the seal base (36) on a facing inner surface of the bag body. The seal portion (4) is shaped to provide continuous wave-shaped portions in which a triangular portion (4B) having a vertex (opening-side end (4A)) and a straight linear portion (4C) are integrated.
