    • The invention relates to a barrier film layer comprising a polymer composition, wherein the polymer composition comprises

      a. an amount of a highly branched polyesteramide (HBPEA), and
      b. optionally, an amount of polyvinylalcohol or a derivative thereof (P(E)VA),
      wherein the sum of the amount of the HBPEA and the amount of the P(E)VA is at least 30 weight %, calculated relative to the weight of the polymer composition, and wherein the amount of the HBPEA is at least 5 weight %, calculated relative to the weight of the polymer composition, and wherein the polymer composition comprises hydroxyl and/or carboxyl functional groups with a combined hydroxyl and carboxyl value of at least 20 mg KOH/g calculated relative to the polymer composition.
      The effect of the barrier film according to the invention is that it can be used to enhance the oxygen barrier properties of polymeric substrates, that it does not generate hydrogen chloride gas when incinerated, that it can be used in applications requiring non-invasive control on metal content and that it has improved adhesion on apolar substrates compared to barrier film layers based on a completely hydrolyzed PVA alone. A further advantage of the barrier film layer according to the invention is an improved printability.
      The invention also relates to a coating composition comprising a polymer composition as described for the barrier film layer. The invention also relates to use of the coating composition for the preparation of a barrier film layer, to a substrate bearing a barrier film layer according to the invention and to an article comprising a substrate according to the invention.
    • 本发明涉及包含聚合物组合物的阻挡膜层,其中聚合物组合物包含a。 一定量的高度支化聚酯酰胺(HBPEA),和b。 任选地,一定量的聚乙烯醇或其衍生物(P(E)VA),其中HBPEA的量和P(E)VA的量的总和为至少30重量%,相对于 所述聚合物组合物,并且其中所述HBPEA的量相对于所述聚合物组合物的重量计算为至少5重量%,并且其中所述聚合物组合物包含羟基和/或羧基官能团,其羟基和羧基的组合值为 相对于聚合物组合物计算至少20mg KOH / g。 根据本发明的阻挡膜的效果在于其可用于增强聚合物基材的氧气阻隔性能,其在焚化时不产生氯化氢气体,其可用于需要非侵入性控制的应用 金属含量,并且与仅基于完全水解的PVA的阻挡膜层相比,其在非极性基材上具有改善的粘合性。 根据本发明的阻挡膜层的另一个优点是改进的可印刷性。 本发明还涉及包含如关于阻挡膜层所述的聚合物组合物的涂料组合物。 本发明还涉及涂料组合物用于制备阻挡膜层,用于带有根据本发明的阻挡膜层的基底的用途以及用于包含根据本发明的基底的制品。
