ABSTRACT:
A packaging material for photographic photosensitive materials which comprises a simultaneously coextruded multilayer film layer comprising a light-absorptive light-shielding thermoplastic resin layer containing low-pressure linear low-density polyethylene resin, 0.1 to 15 wt. % of carbon black and 0.01 to 1 wt. % of a lubricant and being located as the inner layer and a light-reflective light-shielding thermoplastic resin layer being located as the outer layer.
This packaging material is superior in tear strength, impact puncture strength, Gelbo test strength, tensile strength, light-shielding, prevention of temperature elevation at the inside of package under sunlight, moistureproofness, heat resistance, discrimination of right side - reverse side under a safe light, slipping character, heat sealing properties and printability.
