Abstract
A random propylene ethylene copolymer having: i) a xylene soluble fraction at 25° C. ranging from 10 wt % to 16 wt %, based upon the total weight of the random propylene ethylene copolymer; ii) a melt flow rate, MFR, measured according to ISO 1133 at 230° C. with a load of 2.16 kg, ranging from 50.0 g/10 min to 80.0 g/10 min; iii) an ethylene derived units content ranging from 4.7 wt % to 5.8 wt %, based upon the total weight of the random propylene ethylene copolymer; iv) a crystallization temperature measured by DSC, ranging from 82° C. to 105° C.; and v) C13 NMR sequences PEP ranging from 4.0 mol % to 5.8 mol %.
