Transparent film dressings have many of the attributes of the ideal wound dressing. However, currently available film dressings are deficient in their ability to handle varying levels of wound exudate. The permeability of polymeric films to water vapor is discussed and techniques are described to produce films in which the moisture vapor permeability is a function of the moisture in the environment. Illustrations are provided showing the variation of permeability with relative humidity and water contact. The unique properties of coextruded films are illustrated and the responsiveness of such a film dressing to varying conditions at the wound are discussed.
透明薄膜敷料具有理想伤口敷料的许多特性。然而，目前可用的薄膜敷料在处理不同程度伤口渗出液的能力方面存在不足。本文讨论了聚合物薄膜对水蒸气的渗透性，并描述了生产水蒸气透过率随环境湿度变化的薄膜的技术。文中提供了图表，展示了渗透率随相对湿度和水接触的变化情况。阐述了共挤薄膜的独特性能，并讨论了这种薄膜敷料对伤口不同状况的响应性。
