Linear low density polyethylenes (LLDPES) that have relatively high melt index ratios (MIR) and relatively high melt strength (MS). This combination of melt properties is achieved by a substantially non blended LLDPE. Catalysts used to produce these polyethylenes are generally a blend of bridged bis...
