PROBLEM TO BE SOLVED: To provide a flexible packaging body provided with a gas injection portion that has a hardly bent structure to a certain degree and is reduced in the risk that gas may leak.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, one or more gas injection portions, which are surrounded by sealed regions and formed by injection of gas without being sealed across a predetermined length in a vertical direction, are provided at one or both of two side edge portions which are respectively sealed regions, in peripheral edge portions of both side ends of the first side film and the second side film. The gas injection portions are 3 mm or more and 50 mm or less in diameter, and the whole of the gas injection portions are clamped from the first side film side and the second side film side, where repulsion when crushing the clamping width until the width becomes half of the diameter of the gas injection portions is 4 N or more and 30 N or less, at 23°C and 1 atm. |
