POLYETHYLENE COMPOSITIONS HAVING IMPROVED OPTICAL AND MECHANICAL PROPERTIES AND IMPROVED PROCESSABILITY IN THE MELTED STATE

摘要

Polyethylene composition comprising (percentages by weight): A) from 60 to 95 % of an LLDPE copolymer having a density from 0.905 to 0.935 g/cm3, Mw/Mn values less than 4 and F/E ratio values greater than 20; B) from 5 to 40 % of one or more crystalline copolymers of propylene selected from among defined copolymers of propylene with ethylene and/or higher alpha-olefins.
