Title
(KO) 연신 폴리프로필렌 필름
Abstract
(KO)
150℃에서 폴리에틸렌테레프탈레이트(PET)에 필적하는 저수축률을 갖는 연신 폴리프로필렌 필름은, 이하의 요건 (a) 내지 (c)를 만족하는 프로필렌계 중합체를 사용한 연신 필름이며, 또한 이하의 요건 (d) 및 (e)를 만족한다. (a) 메소펜타드 분율이 96% 이상임 (b) 프로필렌 이외의 공단량체의 함유량이 0.5몰% 이하임 (c) 용융 유속(MFR)이 0.5g/10분 이상, 20g/10분 이하임 (d) 광각 X선 산란법에 의해 측정되는 폴리프로필렌의 α형 결정의 110면의 산란 강도를 방위각에 대하여 플롯했을 때의 최대 피크의 반값폭이 30도 이하임 (e) 시차 주사 열량계를 사용해서 승온 속도 20℃/분으로 측정된 융해 흡열 피크 면적(전체 융해열)이 115J/g 이상이고, 또한 150℃ 이하의 면적(150℃ 융해열)의 전체 융해열에 대한 비(150℃ 융해열/전체 융해열)가 0.12 이하임
