PROBLEM TO BE SOLVED: To provide a flexible packaging body provided with a gas injection portion that can self-stand, which is excellent in self-standing performance and productivity.SOLUTION: In the flexible packaging body, in which a first side film, a second side film and a bottom film, which is inserted between the first and the second side films from a fold in a two-folded state, are overlapped one another and peripheral edge portions thereof are sealed to form a storage portion, a gas injection portion is formed by injection of gas into non-sealed regions in the peripheral edge portions of the first side film and the second side film. Loop stiffness of the first side film and the second side film in a direction corresponding to a vertical direction when self-standing the flexible packaging body is 30 mN or more and 1300 mN or less, and loop stiffness of the first side film and the second side film in a direction corresponding to a horizontal direction when self-standing the flexible packaging body is 20 mN or more and 1200 mN or less. |
