    Abstract: The present invention relates to a membrane comprising a bulkhead layer, wherein more than 50% by weight of the bulkhead layer is composed of PVC, and a barrier layer. The barrier layer can, on the one hand, be a barrier layer S1, wherein the barrier layer S1 has a polyvinyl alcohol layer comprising more than 50% by weight of copolymer PA, which is connected to the bulkhead layer by a polyurethane layer, wherein more than 10% by weight of the polyurethane layer is composed of polyurethane PUR. The barrier layer can, on the other hand, be a barrier layer S2, wherein the barrier layer S2 has a composition comprising 5-50% by weight of polyurethane PUR and 50-95% by weight of copolymer PA. The membranes according to the invention have significantly lower plasticizer migration compared to the membranes of the prior art and are distinguished by improved resistance to aging, particularly as regards the adherence of the barrier layer on the bulkhead layer, and imperviousness to damp.

    Abstract translation: 本发明涉及一种包括隔板层的膜，其中隔板层的重量大于50％由PVC构成，并且阻挡层。 一方面，阻挡层可以是阻挡层S1，其中阻挡层S1具有包含大于50重量％的共聚物PA的聚乙烯醇层，其通过聚氨酯层连接到隔板层，其中 聚氨酯层的10重量％以上由聚氨酯PUR组成。 另一方面，阻挡层可以是阻挡层S2，其中阻挡层S2具有包含5-50重量％的聚氨酯PUR和50-95重量％的共聚物PA的组成。 根据本发明的膜与现有技术的膜相比具有显着更低的增塑剂迁移，并且通过改善的耐老化性，特别是关于隔板层上的隔离层在隔板层上的粘附以及防潮性的差异。
