The heat-sealed portion comprises a strongly joined portion and a weakly joined portion, the part surrounded by the strongly joined portion being larger than the photographic photosensitive materials being placed therein with a space, and the light-shielding bag being turned over at least at the edge of the photographic photosensitive materials on the opening side. The package is very easily openable and can ensure sealability, heat sealing properties and physical strength sufficiently.</p>
