Abstract

Abstract Translated from Japanese (57)【要約】 【課題】可剥性、ヒートシール性、滑り性、開封性に優 れたヒートシールフィルムを開発すること。 【解決手段】基材フィルムの少なくとも一方の表面に、 A)a)プロピレン単独重合体成分、またはプロピレン に基づく単量体単位を90モル%より多く含むプロピレ ン系ランダム共重合体成分1〜70重量%、 b)エチレンに基づく単量体単位を10〜40モル%、 プロピレンに基づく単量体単位を90〜60モル%含む プロピレン−エチレンランダム共重合体成分30〜99 重量%よりなり、重量平均分子量(Mw)/数平均分子 量(Mn)が1〜4であるプロピレン系ブロック共重合 体よりなる中間層が積層されてなり、さらに、該中間層 の表面に、 B)密度が0.91〜0.95であるポリエチレン、及 び/またはプロピレンに基づく単量体単位を88〜99 モル%含むプロピレン系ランダム共重合体からなる外表 面層が積層されてなる積層フィルム。 (57) [Abstract] [PROBLEMS] To develop a heat seal film having excellent peelability, heat sealability, slipperiness, and openability. SOLUTION: A) a) a propylene homopolymer component or a propylene-based random copolymer component containing more than 90 mol% of propylene-based monomer units on at least one surface of the base film. %, B) 10 to 40 mol% of an ethylene-based monomer unit, Propylene-ethylene random copolymer component 30 to 99 containing 90 to 60 mol% of propylene-based monomer units And a weight-average molecular weight (Mw) / number-average molecular weight (Mn) of 1 to 4 and a propylene-based block copolymer is laminated on the surface of the intermediate layer. ) Polyethylene having a density of 0.91 to 0.95, and / or 88 to 99 monomer units based on propylene. A laminated film in which an outer surface layer made of a propylene-based random copolymer containing mol% is laminated.
