<p>There is provided a coextruded film or film layer comprises at least two sets of regions, a first set of regions formed predominately of a first thermoplastic polymer and a second set of regions formed predominately of a second thermoplastic polymer arranged in an alternating side-by-side manner. These side-by-side polymer regions generally extend in a machine direction in a continuous manner. The film or film layer has a first face and a second face. On at least one face, one of the regions of the first thermoplastic polymer bridges over the adjacent lane of another (the second thermoplastic polymer region or a third thermoplastic polymer region) thermoplastic polymer region creating on the first face a continuous layer of the first thermoplastic polymer. The opposite face comprises at least in part the other thermoplastic polymer. This bridging layer of the first thermoplastic polymer maintains the integrity of the film or film layer in the cross direction to the machine direction without the need for compatibilizers or tie layers, and allows for the other thermoplastic polymer regions to be exposed on the second face.</p>
