Abstract (en)
[origin: EP0326181A2] A packaging material for photosensitive materials which comprises a single layer polyolefin resin light-shielding film comprising 0.5 to 40 wt. % of polyethylene resin having a melt index of 0.6 to 15 g/10 minutes and a density of 0.931 to 0.965 g/cm<3>, more than 40 wt. % of linear low density polyethylene resin having a melt index of 0.6 to 10 g/10 minutes and a density of 0.919 to 0.930 g/cm<3>, 0.1 to 20 wt. % of carbon black, more than 0.01 wt. % of fatty acid compound and 0.01 to 2 wt. % of antioxidant. A packaging material for photosensitive materials which is a coextruded multilayer inflation film of which the inner surface layer is a polyolefin resin film layer to which 0.5 to 70 wt. % of polyethylene resin having a density of more than 0.936 g/cm<3>. A packaging material for photographic photosensitive materials which comprises an aluminum vacuum metalllized biaxially stretched thermoplastic resin film layer, a long fiber paper layer, of which more than 50 % of the fibers have a fiber length of longer than 3 mm, containing a paper reinforcing agent and having a cool water-extracting pH of 4 to 9, laminated on one side of the above thermoplastic resin film layer, and a polyolefin resin film layer containing 0.1 to 15 wt. % of carbon black having a pH of 4 to 9 and a mean particle size of 15 to 80 m mu and more than 5 wt. % of an ethylene copolymer resin laminated on the other side.
