Abstract

Abstract Translated from Japanese (57)【要約】 (修正有) 【目的】 電子ビーム線に曝されたときに相異なる架橋 度を示す複数の層からなる多層フィルムを提供する。 【構成】 外側層は接着、強度靭性及び熱抵抗性を向上 させるために高度の架橋を有するが、内側層はシール性 を改善するために低い架橋度を有する。本発明の多層フ ィルムから作られた袋は収縮包装用として、殊に大きな 空洞を有する肉の収縮包装用として特に有用である。 (57) [Summary] (Modified) [Objective] To provide a multilayer film composed of a plurality of layers which exhibit different degrees of cross-linking when exposed to electron beam rays. The outer layer has a high degree of crosslinking to improve adhesion, strength toughness and heat resistance, while the inner layer has a low degree of crosslinking to improve sealing. Bags made from the multilayer film of the present invention are particularly useful for shrink wrapping, especially for meat with large cavities.
