The present invention relates to a polyester release film and a method for manufacturing the same. According to the present invention, provided are a polyester release film made of a non-silicone-based material and having excellent peelability and low frictional electrification voltage and a manufacturing method thereof. The polyester release film can be suitably used as a base film for release in the manufacture of a thin film polarizing plate. 본 발명은 폴리에스테르 이형 필름 및 이의 제조 방법에 관한 것이다. 본 발명에 따르면 비-실리콘계 소재로 이루어지면서도 우수한 박리성과 낮은 마찰 대전압을 가지는 폴리에스테르 이형 필름과 이의 제조 방법이 제공된다. 상기 폴리에스테르 이형 필름은 박막 편광판의 제조시 이형용 기재 필름으로 적합하게 사용될 수 있다.
