BIODEGRADABLE SHEET, MOLDED OBJECT OBTAINED FROM THE SHEET, AND PROCESS FOR PRODUCING THE MOLDED OBJECT

摘要

A biodegradable sheet that causes no environmental problems, has excellent heat resistance and impact resistance, and is capable of forming deep-drawn molded article and blister molded article having a complicated shape. The biodegradable sheet comprises a resin composition containing 75 to 25 mass% of a polylactic acid resin and 25 to 75 mass% of a polyester having a glass transition temperature of 0 DEG C or less and a melting point higher than the glass transition temperature of the polylactic acid resin based on total 100 mass%, and the polylactic acid resin in the sheet has a degree of crystallization of 45% or less. The method for producing a molded article from the biodegradable sheet includes the step of molding the biodegradable sheet at a temperature not lower than the melting point of the aliphatic polyester and lower than a temperature by 30 DEG C higher than the melting point of the polyester.
