A) from 65% to 97% by weight of a copolymer of ethylene having:

1) a density of 0.925 g/cm3 or higher; and
2) a MI2 value of 0.5 g/10 min. or greater; and


B) from 3% to 35% by weight of a polyolefin composition made from or containing:

BI) from 5% to 35% by weight of a propylene homopolymer;
BII) from 20% to 50% by weight of an ethylene homopolymer or a copolymer of ethylene with up to 5% by weight of alpha-olefin comonomers, containing 5% by weight or less of a fraction soluble in xylene at 25° C.; and
BIII) from 30% to 60% by weight of a terpolymer of ethylene, propylene, and 1-butene containing from 30% to 85% by weight of a fraction soluble in xylene at 25° C.
