Abstract

본 발명은 필름의 길이방향의 두께 변이가 5% 이하이고 두께 변이의 파형을 푸리에 변환으로 해석했을때 파수영역이 0.15∼0.45(1/m)인 파수성분의 스펙트럼강도 합(Pw1)과 전체 파스영역의 스펙트럼강도 합(PwT)의 비(Pw1/PwT)가 0.20 이하이며, 필름의 길이방향의 두께 변이가 5% 이하이고 파수영역이 1.00∼2.00(1/m)인 파수성분의 스펙트럼강도 합(Pw2)과 전체 파수영역의 스펙트럼강도 합(PwT)의 비(Pw2/PWT)가 0.15 이하인 열가소성 수지필름과 그 제조방법에 관한 것이다. 본 발명에 의한 필름은 두께의 균일성이 크게 개선되며, 2차 가공에서 비틀어지거나 주름이 지는 등의 결함을 방지할 수 있다.
