Abstract

계면활성제를 포함하는 코아 층 및 하나 이상의 외부 층을 갖는 동시압출된 다층 중합체 필름을 성형 구조물상에 놓는다. 성형 구조물은 상기 다층 필름의 이동 방향과 평향한 방향으로 움직이고 상기 방향으로 상기 다층 필름을 전달시킨다. 성형 구조물의 이동 방향에 따라 상기 다층 필름의 두께를 가로질러 유압차를 적용한다. 상기 유압차는 다층 필름이 성형 중합체 웹을 형성하는 성형 구조물과 일치하도록 충분히 크다. 상기 성형중합체 웹은 외부 층으로 코아 층중의 계면활성제가 이동되도록 허용하는 충분히 높은 온도로 노출시켜 계면활성제 처리된 성형 중합체 웹을 형성한다.
