Abstract

본 발명은 우수한 층간 접착력을 나타내는 폴리올레핀층과 에틸렌·비닐알콜 공중합체로 된 다층 적층필름에 관한 것으로 본 발명은 (A)프로필렌 중합체로 된 적어도 1축방향으로 배향된 제1층; (B) 제1층의 프로필렌 중합체의 용점보다 낮은 용점을 갖는 프로필렌 공중합체로 된 제2층; (C) 불포화 카르복실산 또는 그 유도체로 그래프트 된 그래프변성 올레핀 중합체를 함유한 조성물로 된 제3층; 및 (D) 에틸렌·비닐 알콜 공중합체로 된 제4층의 4개층이 이 순서대로 적층된 다층 적층필름이다. 이와 같은 다층 적층 필름은 우수한 층간 접착력을 나타내며, 내열성이 우수하다.
