An oriented multilayer film is provided, the film including in at least one outer layer an ethylene copolymer having a density of 0.900-0.935 g/cm3 and a CDBI of 50-95% the outer layer is in contact with a polypropylene core layer, and the film is made by coextrusion of the ethylene copolymer and the polypropylene layer and subsequent orientation. The coextruded layers can be uniaxially oriented or biaxially oriented without difficulties caused by presence of low molecular weight amorphous polymer fractions inherently present in traditional Ziegler-Natta linear low density polyethylene. The optical properties of oriented polypropylene films can be retained, while the sealing temperature is lowered and the heat seal strength and the hot tack performance properties are improved.
