The invention relates to a multi-layered biaxially oriented polypropylene film consisting of a base layer, a covering layer (I) which is applied to a first side of the film and contains at least between 80 and 100 wt. % of a propylene-ethylene copolymer, and another layer (II) which is applied to the opposing second side and contains between 40 and 100 wt. % of a propylene-ethylene copolymer. The propylene-ethylene copolymer of the two layers contains a maximum of 2.5 wt. % of ethylene and has a melting point between 145 and 160 DEG C. The curl of the film can be controlled very well.
