PROBLEM TO BE SOLVED: To provide a bag body which can be opened widely in an easy manner with a simple configuration, and a manufacturing method of the same.SOLUTION: A bag body 1 includes: a bag body 10; and a zipper tape 20 heat-sealed at an inner surface of the bag body 10. In the bag body 10, base material films 11 are overlapped, a side seal part 12 and a bottom seal part 13 are formed around them and accommodation space 14 is partitioned and formed inside. At both end parts in the longitudinal direction of the zipper tape 20, a first portion 25 and a second portion 26 are provided which are positioned at the side seal part 12, and made to be thinner than a thickness dimension in an engagement direction at a male side strip-like member and a female side strip-like member in an engaged state. The first portion 25 and the second portion 26 are located from an end part in the longitudinal direction of the zipper tape 20 toward an intermediate part side, which is an inner side, sequentially. The second portion 26 is formed to be thinner than the first portion 25. When opening, a force to open the bag body 1 concentrates in the second portion 26, and the bag body can be opened widely. |
