Abstract

본 발명은 종이 대용품의 기재로 사용되는 백색도가 우수한 폴리에스테르 필름 및 그의 제조방법에 관한 것이다.The present invention relates to a polyester film excellent in whiteness used as a substrate for paper substitutes and a method for producing the same.

평균 입경 0.2 내지 10㎛의 무기입자를 커플링제로 표면처리하고 폴리올레핀으로 피복시킨 것을 폴리에스테르에 2내지 50중량% 혼합하고 이축연신 시켜 제조한 본 발명의 폴리에스테르 필름은 겉보기 밀도가 0.6내지 1.1g/㎠, 빛 투과율이 0.5내지 2.0%이고 백색도가 80내지 110%로서, 필름의 광학 물성이 우수할 뿐 아니라 제막연신성이 우수하여 생산성을 향상시킬 수 있으며, 특히 종이 대용품의 기재로 사용하기에 적합하다.The polyester film of the present invention prepared by mixing 2 to 50% by weight of an inorganic particle having an average particle diameter of 0.2 to 10 μm with a coupling agent and coated with a polyolefin in a polyester and then biaxially stretching has an apparent density of 0.6 to 1.1 g. / Cm2, light transmittance of 0.5 to 2.0% and whiteness of 80 to 110%, not only excellent optical properties of the film but also excellent film stretching property can improve productivity, especially for use as a substrate for paper substitutes Suitable.
