POLY (LACTIC ACID) AND POLYOLEFIN FILMS CONTAINING POROSITY AND SORBENTS

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 co...
