Permeable polymer film

A multilayer film comprising:

• a core layer comprising
• a polypropylene composition comprising
• A) from 80 wt % to 65 wt %;
• of a propylene homopolymer having a fraction insoluble in xylene at 25° C. greater than 90 wt %, based upon the total weight of the propylene homopolymer;
• and
• B) from 20 wt % to 35 wt %;
• of a propylene ethylene copolymer having:
• i) xylene soluble fraction at 25° C. ranging from 14 wt % to 27 wt %, based upon the total weight of the propylene ethylene copolymer;
• ii) intrinsic viscosity of the fraction soluble in xylene at 25° C. ranging from 1.0 to 2.4 dl/g;
• iii) melt flow rate, MFR, measured according to ISO 1133 at 230° C. with a load of 2.16 kg, ranging from 1.0 g/10 min to 4.0 g/10 min;
• iv) an ethylene derived units content ranging from 5.0 wt % to 8.0 wt %, based upon the total weight of the propylene ethylene copolymer;
• v) the ethylene derived units content on the fraction insoluble in xylene at 25° C. ranging from 2.5 wt % to 6.0 wt %, based upon the total weight of the propylene ethylene copolymer;
• vi) the ethylene derived units content on the fraction soluble in xylene at 25° C. ranging from 15.2 wt % to 30.2 wt %, based upon the total weight of the propylene ethylene copolymer;
• and
• vii) the C13 NMR sequences PEP measured on the fraction insoluble in xylene at 25° C. ranging from 3.5 mol % to 5.5 mol % and the C13 NMR sequences PEP measured on the fraction soluble in xylene at 25° C. ranging from 11.0 mol % to 14.2 mol %;
• the sum of A) and B) being 100 wt %.
