Abstract

A starch-based biodegradable material composition includes: an enzyme-hydrolyzed starch; and a biodegradable polyester selected from at least one of an aliphatic polyester of polybutylene succinate and an aliphatic-aromatic copolyester. The enzyme-hydrolyzed starch is prepared by hydrolyzing a native starch using a starch-hydrolyzing enzyme. The starch-hydrolyzing enzyme has an activity unit ranging from 15000 to 40000.
