PROBLEM TO BE SOLVED: To provide a process for producing a molding of expandable aliphatic polyester resin particles having biodegradability and a low molding shrinkage. SOLUTION: This process comprises heat-molding expandable aliphatic polyester resin particles having biodegradability and a gel content of at least 5%. It is desirable that the base resin of the expandable aliphatic polyester resin particles is the one that contains at least 60 mol% aliphatic ester component. |
