Document Type and Number:
Japanese Patent JP3138196
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a biodegradable plastic film or sheet excellent in impact resistance and to obtain a biodegradable molding undergoing no change in shape even under high-temperature and high-humidity conditions.
SOLUTION: This film or sheet essentially consists of a polylactic acid polymer and a biodegradable aliphatic polyester having a glass transition point of 0°C or below. It is thermoformable and has a content of the biodegradable aliphatic polyester of 7-60 pts.wt. per 100 pts.wt. polylactic acid polymer. A biodegradable plastic molding is obtained from the above film or sheet.
