PROBLEM TO BE SOLVED: To provide a flexible packaging body provided with a gas injection portion, which can stably keep inner pressure of the gas injection portion.SOLUTION: In the flexible packaging body, in which at least a first side film and a second side film are overlapped each other and peripheral edge portions thereof are sealed to form a storage portion, non-sealed regions, surrounded by sealed regions having sealed the first side film and the second side film, that are regions which are not sealed across a predetermined length are provided in peripheral edge portions of the first side film and the second side film. In the non-sealed regions are injected with gas to form gas injection portions, where oxygen permeability of the non-sealed regions is 30 cc/(m' day' atm) or less. |
