Title (EN) SURFACE PROTECTIVE FILM
(FR) FILM DE PROTECTION DE SURFACE
(JA) 表面保護フィルム
Abstract:
(EN) Provided is a surface protective film that has ultraeasy separability, while having a low possibility of contaminating the surface of an object to which the surface protective film is bonded. A surface protective film according to the present invention has an adhesive layer; and the peel strength as measured by bonding a polyethylene terephthalate film having a thickness of 25 μm to the adhesive layer and peeling the polyethylene terephthalate film therefrom in 30 minutes at 23°C at a peeling angle of 180° and at a peeling rate of 6,000 mm/minute is 0.08 N/25 mm or less.
(FR) La présente invention décrit un film de protection de surface qui présente une séparabilité ultra-facile, tout en ayant une faible possibilité de contamination de surface d’un objet auquel le film de protection de surface est lié. Un film de protection de surface selon la présente invention possède une couche adhésive ; une résistance au décollement telle que mesurée par liaison d’un film de poly(téréphtalate d’éthylène) ayant une épaisseur de 25 µm à la couche adhésive et le décollement du film de poly(téréphtalate d’éthylène) de cette dernière en 30 minutes à 23 °C sous un angle de décollement de 180° et à une vitesse de décollement de 6 000 mm/minute est de 0,08 N/25 mm ou moins.
(JA) 超軽剥離性を備え、被着体表面の汚染性が低い、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、粘着剤層を有する表面保護フィルムであって、該粘着剤層に厚み25μmのポリエチレンテレフタレートフィルムを貼り合せ、23℃で30分後に、該ポリエチレンテレフタレートフィルムを、剥離角度180度、剥離速度6000mm/分において剥がした際の剥離力が0.08N/25mm以下である。
