BREATHABLE MICROLAYER POLYMER FILM AND ARTICLES INCLUDING SAME |
摘要 |
A breathable microlayer polymer film comprising a plurality of coextruded microlayers including a first layer comprising a first melt-extrudable polymer and a second layer comprising second melt-extrudable polymer, the first melt-extrudable polymer having a first water vapor transmission rate and the second melt-extrudable polymer having a second water vapor transmission rate less than the first water vapor transmission rate. A method for making such a breathable film is also disclosed. The microlayer polymer film is breathable, but can also be a barrier to liquid, microbial organisms, organic toxins, and body fluids, and is suitable as a covering material for disposable items such as diapers. While the first polymer is more breathable, the second polymer can impart other properties to the microlayer film such as enhanced tensile properties.
