Abstract

본 발명은 수축라벨, 전성피복 등에 이용되는 열수축 특성이 우수한 폴리 에스테르 수축필름에 관한 것이다.The present invention relates to a polyester shrink film excellent in heat shrinkage characteristics used in shrinkage labels, malleable coating and the like.

본 발명은 80℃보다 더 낮은 온도에서도 높고 균일한 수축률을 얻을 수 있는 PET계 필름을 제공하는 것을 목적으로 한다.An object of the present invention is to provide a PET-based film that can obtain a high and uniform shrinkage even at a temperature lower than 80 ℃.

본 발명은 필름을 구성하는 코폴리에스테르 수지 조성물에 있어서, 디카르본산 성분으로서 테레프탈산을 95 내지 70몰%, 이소프탈산을 5 내지 30몰% 함유하고, 디올성분으로서 에틸렌글리콜을 90 내지 65몰%, 네오펜틸 글리콜을 5 내지 15몰% 및 1.4-시클로헥산디메탄올을 5 내지 20몰% 함유하는 것을 특징으로 한다.In the copolyester resin composition constituting the film, the present invention comprises 95 to 70 mol% of terephthalic acid and 5 to 30 mol% of isophthalic acid as the dicarboxylic acid component, and 90 to 65 mol% of ethylene glycol as the diol component. , 5 to 15 mol% of neopentyl glycol and 5 to 20 mol% of 1.4-cyclohexanedimethanol.
