Abstract

열가소성 수지 필름의 제조방법이 개시된다. 이는 미연신 쉬트를 이축연신후 열처리하는 공정을 포함하는 열가소성 수지 필름의 제조방법에 있어서, 상기 열처리가 다음식 (1), (2) 및 (3)을 만족하도록 수행되는 것을 특징으로 한다.Disclosed is a method for producing a thermoplastic resin film. This is a method for producing a thermoplastic resin film comprising a step of heat treatment after biaxial stretching of an unstretched sheet, characterized in that the heat treatment is performed to satisfy the following formulas (1), (2) and (3).

Tm-60 〈 T1 〈 Tm-10 (1)Tm-60 <T1 <Tm-10 (1)

50 〈 T1-T2 〈 130 (2)50 〈T1-T2 〈130 (2)

5 〈 (T1-T2)/t 〈 25 (3)5 〈(T1-T2) / t 〈25 (3)

상기식에서 Tm은 필름의 용옹온도이며, T1은 열처리 초기온도이고, T2는 열처리 말기온도이며, t는(3) 열처리 시간(초)이다. 이 방법에 따라 제조된 열가소성 수지 필름은 평면성이 우수하여 여러가지 제품에 다양하게 적용될 수 있다.Where Tm is the melting temperature of the film, T1 is the initial temperature of heat treatment, T2 is the final temperature of heat treatment, and t is the heat treatment time in seconds. The thermoplastic resin film produced according to this method has excellent planarity and can be applied to various products.
