Summary: | To provide a thermoplastic resin molding capable of optimizing a maze effect effective for oxygen barrier.SOLUTION: A thermoplastic resin molding includes a resin having water vapor barrier properties, a resin having a functional group and a resin having oxygen barrier properties. The resin having the functional group is a different resin from the resin having water vapor barrier properties. The functional group includes a reactive group that can be bonded with the resin having oxygen barrier properties. A dispersion phase is formed with a core-shell structure in which the resin having the functional group encapsulating the resin having oxygen barrier properties is present as an island in the resin having water vapor barrier properties.SELECTED DRAWING: Figure 1
【課題】酸素バリアに有効である迷路効果の最適化が可能な熱可塑性樹脂成型体を提供すること。【解決手段】水蒸気バリア性を有する樹脂、官能基を有する樹脂および酸素バリア性を有する樹脂を含み、前記官能基を有する樹脂は、前記水蒸気バリア性を有する樹脂と異なる樹脂であり、前記官能基は、前記酸素バリア性を有する樹脂と結合し得る反応基を有し、前記官能基を有する樹脂が前記酸素バリア性を有する樹脂を包み込んだコアシェル構造体が、前記水蒸気バリア性を有する樹脂の中に島として存在する分散相を形成する。【選択図】図1 |
