Abstract: A polypropylene composition made from or containing:



A) from 76 wt % to 95 wt % of a propylene homopolymer having:

fraction soluble in xylene at 25° C. between 2.0 wt % and 4.5 wt %; and
melt flow rate ranging from 60.0 to 110.0 g/10 min; and


B) from 5 wt % to 24 wt % of a copolymer of propylene and ethylene containing from 75 wt % to 90.0 wt % of ethylene derived units;
wherein the polypropylene composition has
content of ethylene derived units in the fraction soluble in xylene at 25° C. lower than the content of ethylene derived units of component B) and ranging from 51.0 wt % to 74.0 wt %; and
at least two melting points, wherein the higher melting points ranges from 156.0° C. to 166.0° C. and the lower melting point ranges from 90.0° C. to 125.0° C.;
wherein the sum of the amounts of component A) and B) being 100 wt %.
