<p>A packaging material for photographic photosensitive materials which comprises a coextruded double layer film comprising a low-pressure linear low-density polyethylene resin layer located on heat sealing side and a polypropylene resin layer or a layer of a polyethylene resin of which density is 0.93 to 0.970 g/cm3 located on the other side, either of the above layers contains 0.5 to 30 g/m2 of metal powder or carbon black, and the above low-pressure linear low-density polyethylene resin layer contains 0.05 to 1% by weight of a lubricant. This packaging material is superior in tear strength, impact puncture strength, tensile strength, light-shielding, moisture proofing, slipping character and heat sealing ability.
