PROBLEM TO BE SOLVED: To provide a storage bag which is sealed with a simple operation, and sealed in an unchanged manner even when the sealing is repeated many times.SOLUTION: The storage bag is formed of a packaging material with a sealant layer being layered on an inner surface, and has side seal parts 14 at least on right and left sides with an upper side thereof being opened. An intermediate seal part 13 across the right and left side seal parts 14 is provided in a projecting manner on an outer surface of any one of the surface side or the back side on a part inside the upper side, and the storage bag is sealed by folding the intermediate seal part 13 with its root section as a base point. When the intermediate seal part 13 is folded back with its root section being the base point after the content is placed from an opening part of the upper side, the return of the folded-back section is controlled by the presence of the intermediate seal part 13, and the closed state is maintained. Thus, the storage bag can be sealed by a simple operation of folding back the bag. |
