Claim:
1. A polyethylene composition comprising: 1) a density from 0.938 to 0.948 g/cm 2) a MIF/MIP ratio from 15 to 25, where MIF is the melt flow index at 190° C. with a load of 21.60 kg, and MIP is the melt flow index at 190° C. with a load of 5 kg, both determined according to ISO 1133; 3) a MIF value from 30 to 45 g/10 min; 4) a Mz value equal to or greater than 1000000 g/mol; 5) a long-chain branching index, LCBI, equal to or greater than 0.55; wherein LCBI is the ratio of the measured mean-square radius of gyration R g , measured by GPC-MALLS, to the mean-square radius of gyration for a linear PE having the same molecular weight.
