PROBLEM TO BE SOLVED: To provide a sterile packaging container which can be inexpensively produced, can be easily opened and closed repeatedly unlike a traditional sterile packaging container which is difficult to open, is difficult to close again after opening, or is expensive when it is formed with a holding tab for opening which has a notch for easy opening owing to a complicated production process required. SOLUTION: In forming this sterile packaging container 30, all the periphery of a synthetic resin laminated film 21 and that of a gas-permeable sheetlike material 12 are heat fused and sealed. On the outside of a part of a heat fused line, a holding tab 18 for opening which is not heat fused is protrusively formed. The laminated film 21 has a curling stress in an opening direction (outward). Also the film 21 has fulged faces 21a, 21b, 21c and 21d in a curl advancing direction. |
