Abstract: A BOPP multilayer film having at least three layers made from or containing a nucleated propylene polymer composition having: A) from 77 wt % to 91 wt %, of a propylene homopolymer having a fraction insoluble in xylene at 25° C. higher than 95%; B) from 9 wt % to 23 wt %, of a copolymer of propylene with from 28.0 wt % to 42.0 wt % of ethylene derived units; and C) a nucleating agent selected from aromatic or aliphatic carboxylic acids, aromatic metal phosphates, sorbitol derivatives and talc, wherein the composition has an intrinsic viscosity (IV) of the fraction soluble in xylene at 25° C. between 1.0 dl/g and 1.9 dl/g, a fraction soluble (Xs) in xylene at 25° C. between 9.0 wt % and 21.0 wt %, a total melt flow rate (MFR) between 1.5 and 5 g/10 min and the value of the relation (I): 22.5+0.2*MFR−1.2*Xs+0.2*IV  (I) higher than 5.9.
