Abstract

나일론(Ny)과 메티크실렌아디프아미드(MXD6)를 40~85:15~60의 중량비로 함유하고, MD방향과 TD방향으로 모두 2.8배이상의 배율로 연신시킨 인열 용이성 연신필름이다. 나일론(Ny)의 구체적인 예를 나일론 66(Ny66), 나일론 6-66공중합체(Ny 6-66)등으로 구성한다. 이 인열 용이성 연신 필름의 제조방법의 기본은 튜우불러법에 의한 2축 연신 공정에 있어서 원 필름을 가열할 때, 버블을 겹쳐 포갰을때의 폭 방향 끝부분의 가열 온도가 후에 제품으로 사용되는 부분의 가열온도보다 낮아지도록 버블의 원주 방향을 따라 제어되어 있다.
필름에 열처리를 하는 공정에서 튜우불러법 또는 텐터법에 따라 필름에 120℃~190℃의 온도에서 제1단계 열처리를 하는 공정과 텐터법에 따라 필름에 190℃~22℃의 온도에서 제2단계 열처리를 하는 공정이 포함한다.
