Abstract

방향족 폴리에스테르 중합체층(A)로 이루어지는(A)의 적어도 1층과, 평균 입경 0.01∼2㎛의 실리카 또는 가교 실리콘 수지입자 A를 함유하고, MFR값이 0.5∼50g/10분의 올레핀계 중합체(B)로 이루어지는 중합체층(B)의 적어도 1층이 교호로 또한 이들의 층간 접착력이 0.1∼20g/㎝의 범위이고 또한 중합체층(A)가 최외층을 형성하여 적층되어 있으며, 중합체층(A)와 중합체층(B)를 박리하였을 때 이 중합체층(A)의 표면의 방전 흔적이 5개/㎡ 이하인 다층이 폴리올레핀인 것을 특징으로 하는 다층 필름으로, 이 다층 필름으로부터 제품 필름을 박리할 때에 생기는 대전을 경감시키고 휩쓸려 들어가는 이물이나 방전 흔적이 적은 제품 필름을 수득할 수 있다.
