There are provided novel multilayer films comprising a layer comprising a thermoplastic polymer, such as an aliphatic-aromatic copolyester (AAPE), with or without filler, and a layer comprising a filled thermoplastic polymer. The polymers in the layers may be the same or different. The multilayer films are preferably characterized by having increased moisture vapor transmission rate (MVTR). Also provided are novel articles of manufacture comprising the novel multilayer films.
新型多层薄膜包括一层热塑性聚合物(如脂肪族-芳香族共聚物(
AAPE))和一层填充热塑性聚合物。各层中的聚合物可以相同,也可以不同。多层薄膜的优选特征是具有更高的湿气透过率(MVTR)。此外,还提供了包含新型多层薄膜的新型制造品。
