Abstract
This invention provides a packaging material for a photographic photosensitive material having a conductive light-shielding thermoplastic resin film layer which comprises a resin composition comprising 3 to 49 wt. % of a thermoplastic elastomer having a crystallinity of 40% or less measured by the X-ray diffraction method, 0.01 to 10 wt. % of lubricant, and 1 to 70 wt. % of carbon black which is acetylene carbon black or furnace carbon black, which is excellent in the dispersion of carbon black to improve light-shielding ability and rare generation of lumps and microgrits, heat sealing properties, small degradation of physical strength, film moldability, etc.
