摘要： Laminated sheet material 9 comprises a laminate of a polyvinyl alcohol or other water-disintegratable film 12 with a thin coextruded film comprising a melt-bondable layer 15 and an impermeable layer 14. The laminate is odor impermeable but water disposable and so can be used to form a toilet-disposable ostomy bag by melt-sealing around the edges 10 between the facing melt-sealable surfaces 15.

摘要： The film is formed by a composition comprising a mixture of 50-100 weight % of an ethylene-butyl-acrylate copolymer (EBA) having a content of butyl-acrylate (BA) of 5-50 weight %, and 0-50 weight % of an elastomeric polyolefin. Laminates comprising a layer constituted by said film have excellent characteristics of noiselessness and softness.

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。
