    • A breathable, stretch-thinned barrier film having improved strength, processability and/or breathability is formed from a mixture of a thermoplastic polymer and cavated filler particles such as cyclodextrin. The cavated filler particles provide the film with enhanced breathability to water vapor due to their ring-like, conical, cylindrical or otherwise hollow molecular structure, yet the film remains substantially impermeable to aqueous liquids. The enhanced breathability occasioned by the cavated particles permits the use of relatively low filler levels and correspondingly high polymer levels, thereby enhancing the film strength. The filler may melt during extrusion of the molten polymer into a film, facilitating smooth processing, and re-crystallize into particles after the film is formed and cooled.
    • 具有改善的强度,加工性和/或透气性的透气的拉伸薄膜阻隔膜由热塑性聚合物和空化填料颗粒如环糊精的混合物形成。 空穴填充剂颗粒由于其环状,圆锥形,圆柱形或其他中空分子结构而使水膜具有增强的透气性,但该膜基本上不能渗透到含水液体中。 由气蚀颗粒引起的增强的透气性允许使用相对低的填料水平和相应的高聚合物水平,从而提高膜强度。 在将熔融聚合物挤出成膜期间,填料可能熔化,促进平滑加工,并且在膜形成和冷却后再填充成颗粒。
