    Abstract: A polyolefin composition made from or containing:



    (A) 10-40% by weight of a copolymer of propylene with hexene-1, is made from or containing 1.0-6.0% by weight, based on the weight of (A), of units deriving from hexene-1 and has a melt flow rate (MFRA) measured according to ISO 1133, 230° C., 2.16 kg ranging from 20 to 60 g/10 min.; and
    (B) 60-90% by weight of a copolymer of propylene with an alpha-olefin of formula CH2═CHR, and optionally a diene, wherein R is H or a linear or branched C2-C8 alkyl and wherein the copolymer is made from or containing 20-35% by weight, based on the total weight of (B), of alpha-olefin,

    wherein

    the polyolefin composition has an amount of fraction soluble in xylene (XS(tot)) at 25° C. equal to or higher than 65% by weight, and

    the amounts of (A), (B), and XS(tot) being based on the total weight of (A)+(B).
