Beschreibung
Zusammenfassung:	The present invention relates to a biodegradable heat-shrinkable polyester film, and more particularly, to a biodegradable heat-shrinkable polyester film which has excellent heat-shrinkable rate and surface slip properties, exhibits a good appearance state after shrinkage, facilitates a physical separation by a specific gravity difference with a polyester bottle in a recycling process, can be biodegraded without a separate treatment of industrial waste such as incineration or the like after being used as a package material, and can actively cope with global warming caused by emissions of air pollutants and greenhouse effect. 본 발명은 생분해성 열수축 폴리에스테르 필름에 관한 것으로서, 보다 상세하게는 열수축율 및 표면 슬립성이 우수하고, 수축 후 외관 상태가 양호하며, 재활용 과정에서 폴리에스테르 병과 비중 차에 의한 물리적 분리가 용이하며, 포장재료로 사용한 후 소각 등 별도의 산업폐기물 처리 없이 생분해 가능하고, 이로 인해 대기 오염물질의 배출과 온실효과로 인한 지구온난화에 적극 대처할 수 있는 생분해성 열수축 폴리에스테르 필름에 관한 것이다.
