(JA) ポリオレフィンフィルム、および離型用フィルム
Abstract
(EN)
The present invention addresses the problem of providing a polyolefin film excellent in terms of releasing property and quality. At least one surface (A surface) of the polyolefin film of the present invention has an average roughness Sa of 65-600 nm, and the A surface has a peak height Sp and a valley depth Sv, the ratio Sp/Sv being 2.5 or less. The polyolefin film has a haze of 30% or less.
(FR)
Le problème de la présente invention concerne un film de polyoléfine qui est excellent en termes de propriété antiadhésive et de qualité. Au moins une surface (surface A) du film de polyoléfine de la présente invention présente une rugosité moyenne Sa de 65-600 nm et la surface A présente une hauteur de pic Sp et une profondeur de vallée Sv, le rapport Sp/Sv étant de 2,5 ou moins. Le film de polyoléfine présente un voile de 30 % ou moins.
(JA)
