  • Breathable microlayer polymer film and articles including same
    Patent number: 6261674
    Abstract: 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.

  • Water degradable microlayer polymer film and articles including same
    Patent number: 6117438
    Abstract: A microlayer polymer film comprising a plurality of coextruded microlayers including a non-degradable layer comprising a non-water degradable, melt-extrudable polymer and degradable layer comprising a water degradable, melt-extrudable polymer. The microlayer polymer film degrades when soaked in water and is suitable as a covering material for disposal items such as flushable diapers. The microlayer polymer film is also breathable and is a barrier to small amounts of water. A suitable non-water degradable, melt-extrudable polymer is linear low density polyethylene filled with a particulate filler. A suitable water degradable, melt-extrudable polymer is polyethylene oxide.
