Propylene random copolymer composition containing (A) 60-85 wt % of a copolymer of propylene and from 0.1 to 2 wt % of units derived from ethylene and having a melt flow rate value according to ISO 1130 (230° C., 2.16 kg) of from 80 to 200 g/10 min; and (B) 15-40 wt % of a copolymer of propylene and from 7 to 17 wt % of units derived from ethylene. The composition has a total ethylene content of from 3 to 4.5 wt %, and a melt flow rate value according to ISO 1133 (230° C., 2.16 kg) of greater than 60 to 150 g/10 min, the composition having not been subject to any form of post-reactor treatment which increases its melt flow rate by more than 5 g/10 min. |
