PROBLEM TO BE SOLVED: To inexpensively produce a packing material excellent in antistatic property, physical strength, suitability to film formation, recycling and incineration and carbon black dispersing property by sticking an inner electrically conductive thermoplastic resin layer to a middle thermoplastic resin layer with an adhesive layer and sticking the middle thermoplastic resin layer to an outer electrically conductive thermoplastic resin layer with an adhesive layer to form a multilayer laminated body. SOLUTION: The packing material for a photographic sensitive material has a multilayer laminated body with an inner electrically conductive thermoplastic resin layer 1a, an outer electrically conductive thermoplastic resin layer 3a, a middle thermoplastic resin layer 2a laminated between the layers 1a and 3a and at least two adhesive layers 4 which stick these layers. The thermoplastic resin layers 1a, 2a and 3a may be molded from various thermoplastic resins but a polyolefin resin-base resin is preferably used because it is inexpensive, has good photographic properties and suitability to incineration and is easily available.
