Propylene ethylene random copolymer

A propylene ethylene copolymer having:

• (i) an ethylene derived units content (C2) ranging from 2.0 wt % to 11.0 wt %, based upon the total weight of the copolymer;
• (ii)) a fraction soluble in xylene at 25° C. (Xs) ranging from 7.1 wt % to 28.5 wt %, based upon the total weight of the copolymer;
• (iii) an intrinsic viscosity of the fraction soluble in xylene at 25° C. ranging from 3.2 dl/g to 5.6 dl/g;
• (iv) a melting point (Tm) higher than 140.0° C. and fulfilling the relation (I):
• Tm>155−1.4×C2 (I),
• wherein Tm is the melting point of the propylene ethylene copolymer measured by DSC and C2 is the wt % of ethylene derived units of the propylene ethylene copolymer, based upon the total weight of the copolymer;
• and
• (v) a flexural modulus (TM) higher than 500 MPa and fulfilling the relation (II)
• TM>1900−285×C2+50×Xs (II),
• wherein TM is the flexural modulus in MPA, C2 is the wt % of ethylene derived units of the propylene ethylene copolymer, based upon the total weight of the copolymer, and Xs is the fraction soluble in xylene at 25° C. (wt %) of the propylene ethylene copolymer, based upon the total weight of the copolymer.
