Zusammenfassung: | PURPOSE: To provide an environment consideration type barrier paper which is excellent in oxygen barrier property and interlayer adhesion before and after bending or before and after bag making, and is reduced in a used amount of an organic solvent, and an environment consideration type gas barrier paper-based laminate, bas barrier paper-based material and gas barrier paper-based package which are made of the barrier paper.SOLUTION: Barrier paper has such layer constitution that at least a paper base material layer, a fixation filler layer, and a gas barrier layer are adjacently laminated in this order, wherein the fixation filler layer contains one or two or more kinds selected from the group consisting of a polystyrene-based resin, a polyurethane-based resin and an acrylic resin, and the gas barrier layer contains a gas barrier resin.SELECTED DRAWING: Figure 1
【目的】本発明は、屈曲前後または製袋前後の酸素バリア性および層間密着性に優れ、有機溶剤の使用量が削減された環境配慮型のバリア紙、および該バリア紙から作製された環境配慮型の、ガスバリア性紙系積層体、ガスバリア性紙系材料、ガスバリア性紙系包装体を提供することを課題とする。【解決手段】少なくとも、紙基材層と、固定目止め層と、ガスバリア層とが、この順に隣接して積層された層構成を有し、該固定目止め層は、ポリスチレン系樹脂、ポリウレタン系樹脂、アクリル系樹脂からなる群から選ばれる1種または2種以上を含有し、該ガスバリア層は、ガスバリア性樹脂を含有することを特徴とする、前記バリア紙。【選択図】図1 |
