BIODEGRADABLE POLYESTER-BASED RESIN EXPANDED PARTICLE, METHOD FOR PRODUCING BIODEGRADABLE POLYESTER-BASED RESIN EXPANDED PARTICLE, BIODEGRADABLE POLYESTER-BASED RESIN EXPANDED MOLDED ARTICLE, AND METHOD FOR PRODUCING BIODEGRADABLE POLYESTER-BASED RESIN EXPANDED MOLDED ARTICLE

摘要

The present invention provides biodegradable polyester-based resin expanded particles having excellent expandability while having crystallinity, as a result of setting a biodegradable polyester-based resin having crystallinity into a specific crystal state. The present invention also provides a biodegradable polyester-based resin expanded molded article that is lightweight and has excellent strength.
