RESIN MOLDING AND METHOD FOR PRODUCING RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a novel resin molding that has excellent transparency and generates little out gas, and to provide a method for producing a resin molding.

SOLUTION: A method for producing a resin molding comprises: supplying a polypropylene-based resin composition as a material P, intermittently from the upstream side of a heating cylinder 2; transporting the supplied material P sequentially from the upstream side to the downstream side of the heating cylinder 2 by rotating a screw 3 disposed in the heating cylinder 2 along an axis of the heating cylinder 2; and removing gas components via a vent hole 4 while the gas components are liberated from the material P by heating and decompressing the heating cylinder 2.
