摘要

A bag body provided with a zipper tape in which both openability by hands and openability by an automatic machine are improved while ensuring the opening strength on the contents side in order to prevent the leakage of the contents is provided. A zipper tape 1 is configured such that the distance A between a front end part 221 of a female part 22 on the non-opening side and a top part 121 on a protruded part 12 on the opening side, the distance B between a front end part 231 of a female part 23 on the non-opening side and a front part 132 opposing to a stripe-shaped base 11 in a protruded part 13 on the non-opening side, and the angle C formed by a protruded part 13 on the non-opening side and a side surface 152 of a shaft part connecting therewith satisfies the relationship represented by the following formula: A-B‰¦0.20 mm and 50°‰¦ C‰¦85°.
