See full text

A film including a top ply, where at least the top ply contains 15 to 90 phr of at least one ethylene-based polymer having a Mooney viscosity (ML1+4, 121° C.) of 50 to 80 Mooney units and 10 to 85 phr of at least one polypropylene having an ISO 178 flexural modulus of greater than or equal to 400 MPa, and the film may be a single-ply or multi-ply film. In some aspects the ethylene-based polymer has a crystallinity of less than or equal to 30%. The top ply may further include at least one compatibilizer, which has, in some cases, a melt flow index MFI (230° C., 2.16 kg) of 0.1 to 4.0 g/10 min.
