摘要: HB polymers, such as copolymers of hydroxy butyric acid and hydroxy valeric acid, are provided as melt extruded films having a thickness of 5 to 200 .mu.m. Sheet materials may consist of such a film or the film may be laminated with other films to increase strength or impermeability. The films are best made by co-extrusion with a thermoplastic that is substantially non-tacky upon solidification. The sheet materials are of particular value as diaper backsheets and ostomy bags. They may include a layer of non-woven material.

摘要翻译: 提供HB聚合物,例如羟基丁酸和羟基戊酸的共聚物,作为厚度为5至200μm的熔融挤出膜。 片材可以由这种膜组成,或者膜可以与其它膜层压以提高强度或不渗透性。 该薄膜最好通过与固化时基本上非粘性的热塑性共挤出来制成。 片材材料作为尿布底片和造口袋具有特别的价值。 它们可以包括一层非织造材料。

摘要: This invention relates to films which have a high degree of silence and pliability and comprise at least one layer formed from a polymeric blend which includes about 40% to 60% by weight of any ethylene and vinyl-acetate copolymer and about 60% to 40% by weight of an elastomeric polyolefin. The elastomeric polyolefin preferably comprises a blend or "alloy" of an ethylene and vinyl-acetate copolymer and an elastomeric ethylene and propylene copolymer. Such films are particularly useful for manufacturing drainage containers or bags for medical applications.
