BIODEGRADABLE RESIN FILM OR SHEET AND PROCESS FOR PRODUCING THE SAME

摘要

A biodegradable resin drawn film or biodegradable resin drawn sheet that is excellent in transparency, impact resistance and film re-forniing capability (recyclability); and a process for producing the same. In particular, a biodegradable resin drawn film or biodegradable resin drawn sheet composed mainly of a mixture of (A) a biodegradable resin of greater than or equal to 30°C as a glass transition temperature Tg and (B) a biodegradable resin of less than or equal to 5°C as a glass transition temperature Tg characterized in that a multiplicity of domains comprising component (B) mainly in the configuration of lamellar or rod-shaped pieces are present in a continuous phase comprising component (A) substantially in parallel to the external surface of the film or sheet; and a process for producing the same.
