Abstract

The invention provides a zipper tape, a packaging bag and a manufacturing method of the packaging bag. One edge portion (224) of a female side band-shaped base (221) on the side of a storage space (15) is made thick to provide a thick portion (31). A cutting portion (32) which is thinner than the female side band-shaped base (221) is provided on the storage space (15) side of the thick portion (31). A sealing base (33) is provided at the storage space (15) side of the cutting portion (32), wherein the sealing base (33) is thicker than the female side band-shaped base (221) and is to be sealed to the inner surface (10A) of a bag body (10) to which a male side band-shaped base (211) is adhered. A sealing strength of the thick portion (31) to the inner surface (10A) on which the male side band-shaped base (211) is adhered is smaller than the seal strength of the sealing base (33). The cutting portion (32) is provided to have a seal strength smaller than the seal strength of the sealing base (33). An area surrounded by the thick portion (31), the cutting portion (32), the sealing base (33), and the inner surface (10A) of the bag body (10) becomes a substantially sealed state, and thus, if a pressure is externally applied to the bag body (10) due to dropping, etc., damage due to extension of the cutting portion (32), etc., can be prevented.

Description

technical field

[0001] The invention relates to a buckle belt and a packaging bag with the buckle belt. Background technique

[0002] Conventionally, there is known a packaging bag with a zipper tape (hereinafter sometimes simply referred to as a "packaging bag") in which a zipper tape is bonded to the inner surface of the bag. When filling such a packaging bag with powder or liquid as the content, the content may leak from the bayonet upward seal side during transportation. Therefore, in order to prevent contents from leaking out, there are known zipper tapes having a spacer structure between the zipper tape and the contents, and packaging bags with zipper tapes (for example, refer to Patent Documents 1 to 3).

[0003] As a spacer structure provided on the zipper tape, for example, there is known a seal capable of easily peeling off a part of the zipper tape from an easily cut cut portion or from the inner surface of the bag. When opening the packaging bag, the cut portio...
