An injection molded article for photographic photosensitive materials is disclosed, which is formed of a noncrystalline resin composition containing 50 wt% or more of a noncrystalline resin having a melt flow rate of from 1 to 60 g/10 min, a flexural modulus of elasticity of 20,000 kg/cm² or more and a thermal deformation temperature of 70°C or higher, from 0.1 to 45 wt% of one or more of a rubbery material, a thermoplastic elastomer and an ethylene copolymer resin, from 0.01 to 49.9 wt% of one or more of a light-shielding material and a fibrous filler and from 0.001 to 20 wt% of one or more of an antioxidant, an age resistor, an ultraviolet absorbent, a fatty acid metal salt, a radical scavenger, a hydrate double salt compound and an oxidation inhibitory synergistic effect-providing agent. Also disclosed are a method for forming the injection molded article for photographic photosensitive materials and a package using the injection molded article for photographic photosensitive materials.
