Abstract

본 발명은 비닐리덴 클로라이드의 단독중합체, 비닐리덴 클로라이드와 비닐 클로라이드와의 공중합체 또는 비닐리덴 클로라이드와 메틸 메타클리레이트와의 공중합체를 함유하는 차단층(12)을 포함하는 산소 및 수분 불투과성 다층 차단 필름(10)에 관한 것이다. 차단층은 열가소성 폴리우레탄, 에틸렌과 α-올레핀과의 사실상 선형 공중합체 또는 균질하게 측쇄된 선형 올레핀 수지를 함유하는 하나 이상의 열 밀봉가능한 표층(14)과 함께 동시 압출되거나 이에 적층되어 다층 차단 필름을 형성한다. 다층 필름은 재사용 가능한 개구 수술 백(24), 약제의 피하운반용 시스템 및 포장시에 사용된 열 밀봉가능한 백에 사용할 수 있다.
