METHOD FOR MANUFACTURING EXPANDED PRODUCT HAVING BIODEGRADABILITY

摘要

PROBLEM TO BE SOLVED: To provide a method for molding, capable of transporting expandable particles made of polylactic acid composition having biodegradability to post processors in the state as it is and to improve foaming in post processing and flexibility and cushioning characteristics of post processing products thereof. SOLUTION: This method comprises molding expanded products mainly containing polylactic acid of L-isomer and D-isomer at a ratio (95:5) to (60:40) and is characterized by previously providing expanded particles mainly comprising polylactic acid, compounding a biodegradable resin having <=40 deg.C glass transition point to the expanded particles and molding the resultant.
