Abstract

본 발명의 폴리프로필렌 복합필름은 (A) 결정성 폴리프로필렌층과, (B) 결정성 폴리프로필렌층(A)의 적어도 한면상에 적층되는 프로필렌/1-부텐 랜덤공중합체층으로 구성되며, 상기 프로필렌-1-부텐랜덤공중합체(B)는 하기 특성들 즉, (1) 상기 공중합체는 프로필렌으로부터 유도된 구성단위 50∼95몰%와 1-부텐으로부터 유도된 구성단위 50∼5몰%로 구성되며; (2) 고유점도가 0.1∼5dl/g이며; (3)분자량분포(Mw/Mn) 값이 3이하이며; (4) 파라미터 B치가 1.0∼1.5이며, 상기 결정성 폴리프로필렌층(A)은 비연신, 일측연신 또는 2축배향된 결정성 폴리프로필렌층일 수 있다. 이 폴리프로필렌 복합필름은 저온가열밀봉성 및 가열밀봉강도와 같은 우수한 가열밀봉성과 열점착성을 가지며 또한 표면점착성이 거의 없으며 양호한 슬립성과 고온에서 고내블록킹성을 나타내도록 고속포장용으로 적합하다. 그외에도 복합 필름은 또한 양호한 투명성과 내긁힘성을 가지므로 식품표장, 충전포장, 및 섬유포장용으로 유리하게 사용할 수 있다.
