WATER DEGRADABLE MICROLAYER POLYMER FILM |
摘要 |
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 disposable 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.
