    摘要： An easily openable package of photographic photosensitive materials which comprises one or a plurality of photographic photosensitive materials and a light-shielding bag having a heat-sealed portion formed on the periphery and packaging the photographic photosensitive materials. 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.

    摘要： A single-sheet gusset bag for photographic photosensitive materials comprising a laminated sheet of which the inner surface layer is a light-shielding polyolefin resin film layer and the outer surface layer is a heat-resistant flexible sheet layer, and having a botom seal portion fixed by a hot-melt adhesive having a softening point by ring and ball method of 75 to 115 C of which the coating amount in the center portion is less than the coating amount of the side portion.In the gusset bag of the invention, the bottom seal portion can be effectively sealed without incidence of fogging and uneven gloss caused by the heat of the hot-melt adhesive. Since the gusset bag is formed of a single sheet, packaging is readily achieved. The cost of the packaging material is also inexpensive.
