Abstract
(EN) The present invention provides a heat-shrinkable multilayer film exhibiting exceptional printability and an excellent finish once mounted. The present invention is a heat-shrinkable multilayer film obtained by laminating obverse and reverse layers containing a polyester resin and an intermediate layer interposed by adhesive layers, wherein the intermediate layer contains a styrene homopolymer and a plasticizer, the intermediate layer having a plasticizer content of 5-35 wt%.
(FR) L'invention fournit un film multicouche thermorétractable excellent en termes d'imprimabilité, et satisfaisant du point de vue de la finition après pose. Plus précisément, l'invention concerne un film multicouche thermorétractable constitué par stratification de couches endroit et envers comprenant une résine polyester, et d'une couche intermédiaire avec des couches d'adhésion pour intermédiaire. Ladite couche intermédiaire comprend un homopolymère styrène et un plastifiant. La teneur en plastifiant dans ladite couche intermédiaire, est comprise entre 5 et 35% en masse.
(JA) 本発明は、印刷適性に優れ、装着後の仕上がりも良好な熱収縮性多層フィルムを提供する。 本発明は、ポリエステル系樹脂を含有する表裏層と、中間層とが、接着層を介して積層されてなる熱収縮性多層フィルムであって、前記中間層は、スチレン単独重合体と、可塑剤とを含有し、前記中間層における前記可塑剤の含有量が5~35重量%である熱収縮性多層フィルムである。
