摘要 |
A nonporous, breathable polymeric film having first and second major layers of polymeric material. The first major layer contains a hydrophilic poly(ether-co-amide) copolymer and a hydrophobic polymer. The second major layer contains one or more polymers, thin films of which meet specifically defined criteria for moisture vapor transmission rate, equilibrium water absorption and equilibrium 70% aqueous isopropanol absorption. The films find use as wound dressings, breathable backing materials or as structural components of such items as surgical gowns, patient drapes or hazardous material protection garments. |
