WESTLAKE HIFOR Polyethylene LT74151 is a high strength linear low density polyethylene containing high slip and high antiblock. It is designed for blown film applications and is well suited for consumer and industrial packaging markets which require impact and tear strength. Films produced using LT74151 exhibit low imperfections and facilitate production at thinner gauges.
