Abstract: An extruded air cooled blown film having a) a total thickness of 5 to 500 μm, b) a mono-layer structure or 2 to 9 coextruded layers, c) at least one layer L containing a polymer selected from the group consisting of polypropylene homopolymers, polypropylene random copolymers, hetero-phasic polypropylene block copolymers, or any mixtures thereof, said polymer having a melt flow rate, according to ASTM D-1238, of 0.1 to 10 dg/min at 230° C. and 2.16 kg, said layer L further containing 0.001 to 2%, relative to the weight of the polymer, of a particular nucleating agent, and optionally d) a Modulus according to EN ISO 527 enhanced by at least 10% versus a reference film without the nucleating agent.
