Abstract

디메틸-2,6-나프탈렌디카르복실레이트, 디메틸테레프탈레이트 및 에틸렌글리콜을 포함하는 자외선 차단성이 우수한 폴리에스터 수지는 360nm이하의 자외선을 차단할 수 있는 공중합체로서, 이를 이용할 경우 별도의 자외선 차단제 첨가나 착색 없이 자외선에 의하여 변질되기 쉬운 과즙 음료나 비타민과 같은 식품 포장용기를 제조할 수 있다,Polyester resins with excellent UV blocking properties, including dimethyl-2,6-naphthalenedicarboxylate, dimethyl terephthalate and ethylene glycol, are copolymers that can block UV rays below 360nm. I can manufacture food packaging such as juice and drink which is easy to be deteriorated by ultraviolet rays without coloring.
