Abstract
본 발명은 열수축성 폴리에스테르 필름에 관한 것으로서, 더욱 상세하게는 주쇄의 반복단위가 에틸렌테레프탈레이트 및 에틸렌이소프탈레이트로 이루어진 폴리에스테르 중합체에 디에틸렌글리콜 및 2,6-나프탈렌디카르복실산을 공중합시킴으로서, 자연수축이 없고 특정온도에서 수축이 균일하며 내열온도를 향상시킬 수 있는 열수축성 폴리에스테르계 필름에 관한 것이다.The present invention relates to a heat-shrinkable polyester film, and more particularly, by copolymerizing diethylene glycol and 2,6-naphthalenedicarboxylic acid in a polyester polymer whose repeating unit of the main chain is ethylene terephthalate and ethylene isophthalate. The present invention relates to a heat shrinkable polyester film having no natural shrinkage, uniform shrinkage at a specific temperature, and improved heat resistance temperature.
