    摘要: A front cover, a rear cover and a base portion are crushed into a crushed material, and further pelletized into a recycled plastic pellet. The recycled plastic pellet is used as a part of a molding material to produce mold plastic parts for a photosensitive material. When the molding material is melt in heat, a thermoplastic resin is deteriorated by heat or modified. Therefore, properties and qualities of recycled plastic mold parts are less than those of new ones. Further, when the thermoplastic resin is deteriorated by heat, the photosensitive material reacts with the thermoplastic resin to decomposed products having an bad influence on photographic characteristics. In order to prevent the deterioration by heat, oxidation inhibiting materials are added, and in order to absorb the decomposed products, carbon blacks are added.
