Abstract: The invention relates to a composition comprising: a) a propylene homopolymer or propylene-ethylene copolymer having an ethylene content of at most 1.5 wt % based on the weight of the propylene-ethylene copolymer, said a propylene homopolymer or propylene-ethylene copolymer having: i) a Mw/Mn in the range of 4.0 to 12, wherein Mw stands for the weight average molecular weight and Mn stands for the number average molecular weight and wherein Mw and Mn are measured according to ASTM D6474-12; ii) an XS in the range from 1.0 to 8.0 wt %, wherein XS stands for the amount of xylene solubles which are measured according to ASTM D 492-10; and iii) a melt flow rate in the range of 1 to 10 dg/minas measured according to ISO1133:2011(2.16 kg/230° C.); b) a first additive, being one or more tocopherols and/or one or more tocotrienols; and c) a second additive, being an organic acid scavenger. The invention moreover relates to a biaxially oriented polypropylene (BOPP) film comprising said composition, to a process for the preparation of a biaxially oriented polypropylene (BOPP) film and to the use of the composition for the preparation of an article, preferably a BOPP film.
