Title
(EN) TEARABLE NON-STRETCHED RESIN FILM AND LAMINATED FILM FOR PACKAGING MATERIAL USING SAME
(FR) FILM DE RÉSINE NON ÉTIRÉ DÉCHIRABLE ET FILM STRATIFIÉ POUR MATÉRIAU DE CONDITIONNEMENT L'UTILISANT
(JA) 易引裂性無延伸樹脂フィルム、及びそれを用いた包装材用積層フィルム
Abstract
(EN)
The purpose is to provide a resin film having tearability. A tearable non-stretched resin film comprising a blend of a polyethylene terephthalate resin and a second resin having a difference from the SP value of the polyethylene terephthalate resin of 1.1-4.0 (cal/cm3)0.5. Provided is a laminated film for a packaging material 1B equipped with this tearable non-stretched resin film 10 between an inner layer film 20 that serves as a heat seal surface and a surface layer film 30 comprising an isophthalic acid-modified polyethylene terephthalate resin in which the copolymer ratio of the isophthalic acid component is 0-5 mol%.
(FR)
L'objectif de l'invention est de fournir un film de résine présentant une aptitude à la déchirure. Ce film de résine non étiré déchirable comprend un mélange d'une résine de téréphtalate de polyéthylène et d'une seconde résine ayant une différence de la valeur SP de la résine de téréphtalate de polyéthylène de 1,1 à 4,0 (cal/cm 3 ) 0,5 . L'invention concerne un film stratifié destiné à un matériau de conditionnement 1B équipé de ce film de résine non étiré déchirable 10 entre un film de couche interne 20 qui sert de surface de thermoscellage et un film de couche de surface 30 comprenant une résine de téréphtalate de polyéthylène modifiée par l'acide isophtalique, dans laquelle le taux de copolymère du composant d'acide isophtalique est de 0 à 5 %.
(JA)
易引裂性を有する樹脂フィルムを提供することを目的とする。 ポリエチレンテレフタレート系樹脂と、前記ポリエチレンテレフタレート系樹脂のSP値との差が1.1~4.0(cal/cm0.5である第2樹脂とのブレンドからなる易引裂性無延伸樹脂フィルムである。この易引裂性無延伸樹脂フィルム10を、ヒートシール面となる内層フィルム20と、イソフタル酸成分の共重合比率が0~5モル%であるイソフタル酸変性ポリエチレンテレフタレート樹脂からなる表層フィルム30との間に備える包装材用積層フィルム1Bが提供される。
