PROBLEM TO BE SOLVED: To provide an injection-molded container of an impact resistant polystyrene-based resin, obtained by an injection molding method through the packing step of a molten resin and a cooling step, excellent in sealing strength, and made fire retardant without using a halogen compound. SOLUTION: This injection-molded container of an impact resistant polystyrene-based resin, excellent in sealing strength, and made fire retardant without using a halogen compound is an impact resistant polystyrene-based resin molding obtained by an injection molding method through the packing step of the molten resin and the cooling step. Arbitrary one face or plural faces of the molding are sealed with a polymer film, and the impact resistant polystyrene-based resin includes gummy particles dispersed in the resin in a particulate shape. The dispersed particles have 1.0-3.0μm average particle diameter. |
