Long-term storage is possible at low cost. The photosensitive material packaging material has an innermost layer on the side where the photosensitive material is packaged, an outermost layer on the side where the photosensitive material is not packaged, and an aluminum foil layer interposed between the innermost layer and the outermost layer. Then, the aluminum foil layer and the innermost layer are bonded by extrusion lamination bonding. The innermost layer is a light-shielding / sliding polyolefin resin film layer mainly composed of an ethylene / α-olefin copolymer resin containing light-shielding properties, a lubricant, an antioxidant, and an antistatic agent. . The outermost layer is a nylon film layer. [Selection] Figure 6 |
