Abstract: Polyethylene composition with improved balance of mechanical and optical properties, comprising (all percentages being by weight): A) from 90 to 99.7% of a LLDPE having a density from 0.91 to 0.94 g/cm3 and a ratio MIF/MIE equal to or higher than 20, where MIF is the melt flow index at 190° C. with a load of 21.60 kg, and MIE is the melt flow index at 190° C. with a load of 2.16 kg, both determined according to ISO 1133; B) from 0.3 to 10% of a LDPE having MIE from 0.1 to 0.6 g/10 min.
