Title (EN) DOUBLE-SIDED ADHESIVE TAPE
(FR) RUBAN ADHÉSIF DOUBLE FACE
(JA) 両面粘着テープ
Abstract:
(EN) The purpose of the present invention is to provide a double-sided adhesive tape having an excellent impact absorption property and a re-peeling property while being thin. The present invention is a double-sided adhesive tape having an acryl adhesive layer on both surfaces of a substrate comprising a polyolefin foam, wherein the thickness of said substrate comprising the polyolefin foam is 50-120 μm, wherein the average air bubble diameters of said substrate comprising the polyolefin foam in an MD direction and in a TD direction are 30 μm or more and 70 μm or less, and wherein the total thickness of the double-sided adhesive tape is 80-150 μm.
(FR) L'invention vise à fournir un ruban adhésif double face présentant une excellente propriété d'absorption des chocs et une excellente propriété de redécollement tout en étant mince. La présente invention concerne par conséquent un ruban adhésif double face ayant une couche adhésive acrylique sur les deux surfaces d'un substrat comprenant une mousse de polyoléfine, l'épaisseur dudit substrat qui comprend la mousse de polyoléfine étant de 50 à 120 µm, le diamètre moyen des bulles d'air dudit substrat qui comprend la mousse de polyoléfine dans une direction MD et dans une direction TD étant de 30 µm ou plus et de 70 µm ou moins, et l'épaisseur totale de la bande adhésive double face étant de 80 à 150 µm.
(JA) 本発明は、薄型でありながらも衝撃吸収性及び再剥離性に優れた両面粘着テープを提供することを目的とする。本発明は、ポリオレフィン発泡体からなる基材の両面にアクリル粘着剤層を有する両面粘着テープであって、前記ポリオレフィン発泡体からなる基材の厚みが50~120μmであり、前記ポリオレフィン発泡体からなる基材のMD方向及びTD方向における平均気泡径が30μm以上、70μm以下であり、両面粘着テープの総厚みが80~150μmである両面粘着テープである。
