Abstract: The present invention related to a film comprising multiple co-extruded film layers, the film having a length and a width, and a thickness defined as the dimension of the film perpendicular to the plane defined by the length and the width, wherein the film is a bi-axially oriented film comprising at least a core layer A, having a first and a second surface, and one or two sealing layer(s) B, wherein the core layer A comprises a polypropylene, and wherein the sealing layer B comprises >50.0 wt % of a polyethylene comprising moieties derived from ethylene and moieties derived from an α-olefin comprising 4 to 10 carbon atoms, the polyethylene having a density of ≥870 and ≤920 kg/m3 as determined in accordance with ASTM D1505 (2010), with regard to the total weight of the sealing layer B, wherein the sealing layer B directly adheres to one of the first or second surface of the core layer A. Such film allows for the production of a sealed package having a sufficiently high sealing strength at reduced sealing temperatures, also referred to as the seal initiation temperature.
