PURPOSE:To improve environmental resistance by using a carbon black, metallic powder, polyoxyethylene alkyl amine, fatty acid monglyceride, aliphat, acid amide, polydimethylsiloxane compd., and ethylene copolymer resin respectively at specific ratios. CONSTITUTION:The packaging material for photographic sensitive materials is constituted of a light shieldable polyolefin film 1a. The light shieldable polyolefin film 1a is constituted by incorporating 0.05 to 20wt.% carbon black and/or metallic powder, 0.01 to 0.5wt.% polyoxyethlene alkylamine, 0.01 to 0.5wt.% acid amide and/or polydimethylsiloxane compd., and>=5wt.% ethylene copolymer resin therein. As a result, the excellent bag making characteristic, hermetic heat sealability, light shieldability, and antistatic property are obtd. and the environmental resistance thereof is improved. |
