Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 エチレン、アクリル酸エステルおよび、マレ イン酸無水物とメタアクリル酸グリシジルとからなる群 れから選ばれる第3成分からの三元共重合体と、該三元 共重合体のガラス転移温度より高いガラス転移温度を有 する酸素遮断性ポリマー(典型的にはエチレン-ビニー ルアルコール共重合体)とのブレンド樹脂からなる酸素 遮断層を少なくとも1層有する、高度に延伸性で熱収縮 可能な、低酸素透過性プラスチックフィルム。 【効果】 エチレン−ビニールアルコール共重合体に、 本発明の三元共重合体をブレンドすることによって、高 湿度においても高い酸素透過性を維持できるようにな り、可塑化によって加工性も改善されて、はハロゲンを 含まず、環境的に配慮された性能の優れた食品包装用フ ィルムを提供する。 (57) [Summary] [Composition] A terpolymer from a third component selected from the group consisting of ethylene, an acrylic ester, and maleic anhydride and glycidyl methacrylate, and the terpolymer. Highly stretchable and heat-shrinkable, having at least one oxygen barrier layer composed of a blended resin with an oxygen barrier polymer having a glass transition temperature higher than that of (typically ethylene-vinyl alcohol copolymer) Possible low oxygen permeable plastic film. [Effect] For ethylene-vinyl alcohol copolymer, By blending the terpolymer of the present invention, it becomes possible to maintain a high oxygen permeability even in high humidity, the processability is improved by plasticization, and it does not contain halogen and is environmentally friendly. And a film for food packaging having excellent performance.
