PURPOSE: To obtain a photographic sensitive material packing material enhanced in transparency and lubricity while preventing the generation of white powder due to bleeding by incorporating a silicone oil having an amide group into the material.

CONSTITUTION: A vessel 1 for a photographic film cartridge consists of a vessel main body 2 and a cap 3 to be engaged with the main body 2. The main body 2 and cap 3 are formed by injection molding. A silicone oil having an amide group is incorporated into the photographic sensitive material packing material. Various thermoplastic resins are used for the packing material, and polyolefin, polystyrene, PVC, ABS, polyvinyl acetate, polyacrylate, polyamide, polycarbonate, polymethyl methacrylate, polyester, polyacrylonitrile and polyvinyl ether resins, etc., are exemplified as the resin.
