PROBLEM TO BE SOLVED: To obtain an injection-molded product for packaging of a photographic sensitive material, the product which has excellent impact resistance and rigidity and which does not deteriorate the photographic sensitivity of the photosensitive material even when the photosensitive material is stored for a long time, by controlling the hydrogen cyanide content of the injection-molded product to a specified value or smaller. SOLUTION: This injection-molded product for packaging of a photographic sensitive material contains an ABS resin prepared by graft polymn, by 25 to 45 wt.% and has >=10 kg.cm/cm Izod impact strength. The hydrogen cyanide content of the injection-molded product is controlled to <=0.2 mg/kg. When the proportion of the graft ABS resin ranges from 25 to 45 wt.%, enough Izod impact strength can be obtd., and the proportion is preferably from 27 to 40 wt.%, and more preferably from 31 to 35 wt.%. Preferably, the graft ABS resin consists of the polymers of 10 to 40 pts.wt. of acrylonitrile monomers, 80 to 110 pts.wt. of butadiene monomers and 60 to 80 pts.wt. of styrene monomers.
