(JA) 表面保護フィルム
Abstract: front page image
(EN)A surface protection film is provided with a polyolefin base material layer and an adhesive layer, wherein the adhesive layer has a hardness (Martens hardness) of 1-2.5 N/mm2 and a loop tack of 0.02-0.1 N/25mm. Therefore, the surface protection film has easy let-off from the surface of the base material even in the case of rolled products, and further is capable of obtaining sufficient adhesive strength to adherends such as prism sheets, which have projections on the surface thereof.
(FR)Le film de protection superficiel ci-décrit est pourvu d'une couche en un matériau de base de type polyoléfine et d'une couche adhésive, ladite couche adhésive ayant une dureté (dureté de Martens) de 1 à 2,5 N/mm2 et une force d'adhérence instantanée de 0,02 à 0,1 N/25 mm. Par conséquent, le film de protection superficiel est facile à décoller de la surface du matériau de base, même dans le cas d'un produit en rouleau, et permet, en outre, d'obtenir une force d'adhérence suffisante à un support comportant des protubérances sur la surface d'une feuille de prisme et autre.
(JA) 表面保護フィルムは、ポリオレフィン系の基材層と、粘着層とを備え、前記粘着層の硬度(マルテンス硬さ)が1N/mm以上2.5N/mm以下であり、ループタックが0.02N/25mm以上0.1N/25mm以下である。それ故、前記表面保護フィルムは、巻重体製品とした場合にも基材面からの巻き出しが容易となり、かつ、プリズムシートのような表面に突起状物を有する被着体に対する十分な密着強度も得ることができる。
