Abstract

본 발명은 열가소성 수지로 된 사이트를 종연신, 횡연시 및 열처리 하여 이축배향 필름을 제조하는 방법에 있어서, 횡연신 장치에서 예열 공정 중 필름에 3 내지 5%의 횡방향 이완을 부여하고, 전체 횡연신의 55% 이상을 횡연신 공정의 전반부에 수행하는 것을 특징으로 하는 방법에 관한 것으로서, 상기에 의해 수득된 열가소성 수지 필름은 횡연식 장치(텐터) 내에서의 횡연신 및 열고정 과정에서 야기되는 필름의 보우잉(bowing) 현상이 억제되어 횡방으로 균일한 물성을 가진다.The present invention provides a method for producing a biaxially oriented film by longitudinally stretching, transversely stretching and heat treating a site made of thermoplastic resin, wherein the transverse stretching apparatus gives 3 to 5% of lateral relaxation to the film during the preheating process, A method characterized in that at least 55% of the stretching is carried out in the first half of the transverse stretching process, wherein the thermoplastic resin film obtained above is caused by the transverse stretching and heat setting process in the transverse stretching apparatus (tenter). Bowing phenomenon of the film is suppressed to have uniform physical properties in the transverse direction.
