POLY (LACTIC ACID) AND POLYOLEFIN FILMS CONTAINING POROSITY AND SORBENTS |
摘要 |
<p>Single and multilayer porous polyolefin films are prepared by extruding polyolefin with poly(lactic acid) (PLA) and followed by uniaxial or biaxial stretching. PLA is used as a pore former that creates porosity. The film provides adjustable gas and water vapor transmission rate by varying the PLA content. Sorbents may optionally be added in the formulation in selective layers. The porous films are useful in packaging and consumable applications. In particular partially miscible blends of PP and PLA is useful for creating fine porosity due to the fine PLA domains in the miscible blends.</p> |
