Title
(EN) SURFACE PROTECTIVE FILM
(FR) FILM DE PROTECTION DE SURFACE
(JA) 表面保護フィルム
Abstract
(EN) Disclosed is a surface protective film which exhibits high adhesion and excellent unwinding characteristics. The surface protective film is characterised in that: the surface protective film comprises at least two layers, which are a surface layer (A) and an adhesive layer (X); the surface layer (A) comprises a propylene polymer and the surface roughness (Ra) of the surface layer is within the range of 0.2-2.0μm; the adhesive strength of the surface protective film with acrylic is 1N/50mm; and the adhesive layer (X) is formed from an olefinic elastomer and/or a styrene elastomer.
(FR) La présente invention se rapporte à un film de protection de surface doté d'une capacité d'adhésion élevée et d'excellentes caractéristiques de déroulement. Le film de protection de surface selon l'invention est caractérisé en ce que : le film de protection de surface comprend au moins deux couches, qui sont une couche de surface (a) et une couche adhésive (X) ; la couche de surface (a) comprend un polymère propylène et la rugosité de surface (Ra) de la couche de surface se situe dans une plage allant de 0,2 à 2,0 μm ; la résistance d'adhésion du film de protection de surface sur de l'acrylique est de 1 N/50 mm ; et la couche adhésive (X) est formée à partir d'un élastomère oléfinique et/ou d'un élastomère styrène.
(JA)  本発明は、高い粘着力と、優れた巻き戻し性を有する表面保護フィルムを提供することを課題とする。 本発明は、表面層(A)および粘着層(X)の少なくとも2層からなる表面保護フィルムであり、表面層(A)が、プロピレン系重合体からなり、かつ表面層の表面粗さ(Ra)が0.2~2.0μmの範囲にある表面保護フィルムである。また、アクリルに対する粘着力が、1N/50mmである上記表面保護フィルムであり、さらには、粘着層(X)がオレフィン系エラストマーおよび/またはスチレン系エラストマーから形成されることを特徴とする上記表面保護フィルムである。
