Abstract
Provided are linear low density polyethylene (LLDPE) compositions including a LLDPE polymer and from 100 ppm to 10,000 ppm of a high molecular weight ethoxylate polymer processing aid (PPA) that is substantially free of fluorine-containing compounds. Also provided are polyolefin masterbatches including from 1 wt. % to 50 wt. % of such inventive high molecular weight ethoxylate PPAs and methods of decreasing melt fracture % in linear low density polyethylene films by blending such high molecular weight ethoxylate polymer processing aids and polyolefin masterbatches into cast films and blown films during extrusion processing.
