Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 原紙に熱可塑性樹脂を押出しラミネートして なる積層体において、原紙として、その抄造時に酸性サ イズ剤を用いたものであって、かつその押出しラミネー トすべき面の王研式平滑度が50秒以下であるものを使 用したことを特徴とする包材用積層体である。 【効果】 原紙に熱可塑性樹脂を押出しラミネートして なる積層体において、押出しラミネートに用いられる溶 融した熱可塑性樹脂の押出し温度が低くても原紙と熱可 塑性樹脂の接着は強固であって、かつ異臭の発生の少な い包材用積層体が得られるようになる。 (57) [Summary] [Structure] In a laminate obtained by extruding and laminating a thermoplastic resin on a base paper, the base paper uses an acidic sizing agent at the time of papermaking, and is formed on a surface to be extruded and laminated. A laminate for a packaging material, characterized in that a material having a grinding smoothness of 50 seconds or less is used. [Effect] In a laminate obtained by extruding and laminating a thermoplastic resin on a base paper, even if the extrusion temperature of the molten thermoplastic resin used for the extrusion lamination is low, the adhesion between the base paper and the thermoplastic resin is strong and an unpleasant odor Thus, a laminate for a packaging material with less occurrence of cracks can be obtained.
