Title
(EN) SURFACE PROTECTION FILM
(FR) FILM DE PROTECTION DE SURFACES
(JA) 表面保護フィルム
Abstract
(EN) Provided is a surface protection film which exerts appropriate adhesive properties even to an adherend having a rough surface and which exhibits excellent back surface slidability, blocking resistance, and reeling properties. Specifically, disclosed is a surface protection film which has a laminate structure comprising at least an adhesive layer and a back surface layer, wherein: the adhesive layer is mainly formed from a styrene-based elastomer; the back surface layer is mainly formed from a propylene-based resin containing 0.5 weight% to 10 weight% of a fluorine-containing compound having a polyfluoro-hydrocarbon group and a polyoxyethylene group, and has a 10-point average surface roughness (Rz) of 3µm or more; and the surface protection film has an initial adhesion strength of 1N/25mm or more in relation to a SUS304 plate, which was subjected to a #320 hair-line processing treatment, and has a reeling strength of 0.5N/25mm or less when the rolled-up film is being reeled.
(FR) La présente invention porte sur un film de protection de surfaces qui possède des propriétés adhésives appropriées même sur une partie adhérée présentant une surface rugueuse, et qui présente d'excellentes propriétés de glissement de la face arrière, de résistance à l'adhérence accidentelle, et de bobinage. L'invention porte plus précisément sur un film de protection de surfaces qui possède une structure stratifiée comprenant au moins une couche adhésive et une couche de face arrière, dans laquelle : la couche adhésive est essentiellement formée d'un élastomère à base de styrène ; la couche de face arrière est essentiellement formée d'une résine à base de propylène contenant 0,5 % en poids à 10 % en poids d'un composé fluoré portant un groupe polyfluorohydrocarboné et un groupe polyoxyéthylène, et présente une rugosité moyenne de surface en 10 points (Rz) supérieure ou égale à 3 µm ; et le film de protection de surface a une force adhésive initiale supérieure ou égale à 1 N/25 mm sur plaque en acier inoxydable (SUS304), qui a été soumise à un traitement de brossage (grain 320), et présente une résistance au bobinage inférieure ou égale à 0,5 N/25 mm lorsque le film enroulé est déroulé.
(JA) 表面が粗面な被着体に対しても適度な粘着特性を有し、かつ、背面の滑り性に優れ、耐ブロッキング性、巻出し特性にも優れた表面保護フィルムを提供する。 本発明の表面保護フィルムは、少なくとも粘着層と背面層の積層形態からなり、該粘着層はスチレン系エラストマーから主としてなり、該背面層はポリフルオロ炭化水素基及びポリオキシエチレン基を有する含フッ素化合物を0.5重量%~10重量%含有したプロピレン系樹脂から主として構成され、かつ、該背面層の表面粗さが十点平均粗さ(Rz)で3μm以上であって、#320ヘアライン加工処理が施されたSUS304板に対する初期粘着力が1N/25mm以上、かつ、ロール状に巻き取られたフィルムを巻き出す際の巻出力が0.5N/25mm以下からなる。
