BIODEGRADABLE CONTAINER AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide a biodegradable container capable of suppressing its biodegradation in a period of using it as a container even on putting a material in which microorganisms can propagate and also rapidly biodegraded after once being put in a compost environment. SOLUTION: This container is characterized by molding a crystalline aliphatic polyester sheet having 100-2,000μm thickness and a slope of its crystallization degree in its thickness direction and arranging the highly crystallized surface of the aliphatic polyester sheet at the inside surface of the container.
