Title (EN) PROTECTIVE FILM
(FR) FILM PROTECTEUR
(JA) 保護フィルム
Abstract:
(EN) This protective film 10 is used adhered on to a resin substrate 21, when thermal-bending the resin substrate 21 under heat. The protective film 10 has a base material layer and an adhesive layer positioned between this base material layer and the resin substrate 21 and adhering to the resin substrate 21. The base material layer comprises a laminate having: a first layer positioned on the opposite side to the adhesive layer, containing a thermoplastic resin, and having a melting point of at least 150°C; and a second layer positioned on the adhesive layer side, containing a thermoplastic resin, and having a melting point of less than 120°C.
(FR) L'invention concerne un film protecteur (10) utilisé collé sur un substrat de résine (21), lors du pliage thermique du substrat de résine (21) sous la chaleur. Le film protecteur (10) a une couche de matériau de base et une couche adhésive positionnée entre cette couche de matériau de base et le substrat de résine (21) et adhérant au substrat de résine (21). La couche de matériau de base comprend un stratifié ayant : une première couche positionnée côté opposé à la couche adhésive, contenant une résine thermoplastique, et ayant un point de fusion supérieur ou égal 150 °C ; et une seconde couche positionnée côté couche adhésive, contenant une résine thermoplastique, et ayant un point de fusion inférieur à 120 °C.
(JA) 本発明の保護フィルム10は、樹脂基板21に対して、加熱下で熱曲げ加工を施す際に、この樹脂基板21に貼付して用いられる。保護フィルム10は、基材層と、この基材層と樹脂基板21との間に位置し、樹脂基板21に粘着する粘着層とを有する。基材層は、前記粘着層の反対側に位置し、熱可塑性樹脂を含有する融点が150℃以上の第1の層と、前記粘着層側に位置し、熱可塑性樹脂を含有する融点が120℃未満の第2の層とを有する積層体で構成される。
