Abstract:
An ethylene polymer blend comprising a preponderance of polymerized ethylene having a density of at least about 0.930 g/cc, a flow index or high load melt index (I.sub.21) of at least about 2 g/10 min., a melt flow ratio (MFR) of at least about 60, and a polydispersity index of at least about 8 but not greater than 18, the polymers of said blend consisting essentially of at least about 0.3 weight fraction of a relatively high molecular weight (HMW) component having a density of at least about 0.900 g/cc, a flow index or high load melt index (I.sub.21) of at least about 0.2 g/10 min., and a flow ratio (FR) at least about 12, and a relatively low molecular weight (LMW) component having a density of at least about 0.930 g/cc and a melt index (I.sub.2) no greater than about 1000 g/10 min.
