A polyethylene composition having the following features:n 1) density from 0.945 to 0.958 g/cm 3 , determined according to ISO 1183 at 23° C.; 2) ratio MIF/MIP from 20 to 43; 3) MIF from 4.0 to less than 8.5 g/10 min.; 4) HMWcopo index from 3.5 to 20; and 5) long-chain branching index, LCBI, equal to or lower than 0.82. The polyethylene composition can be used to produce blown films. |
