PROBLEM TO BE SOLVED: To provide a both-bottom sticking bag capable of surely restraining content leakage for a market place, by dispensing with a precise adjustment and an adjustment operation time, without requiring material much, when manufacturing both-bottom sticking bag.SOLUTION: In a state of sticking inner reinforcement paper 16 of forming a hole 17a having a width W wider than a vertical width D of a bottom surface, having the length L in the lateral direction of a degree stickable to respective left-right triangular folding-in parts 7 and 8 in a development surface 2A and communicating with the inside of a bag body 1, that is, a width R of the hole 17a longer than the vertical width D of the bottom surface, to the development surface 2A of one bottom surface 2, a bag body folding stripe in the development surface 2A of the one bottom surface 2 is bent inside as a folding line, and an inner reinforcement part side folding stripe in the inner reinforcement paper 16 is bent inside as the folding line, and the one bottom surface 2 is formed by sticking a passage communicating with the hole 17a and a part except for the hole 17a from an end part on one nozzle blowing-in port side of left-right end parts of the inner reinforcement paper 16. |
