Abstract:
The present invention generally pertains to multilayer film including four or more discrete layers. The films contain two external layers, an internal stiffening layer and an internal shrink layer. The external layers include linear low density polyethylene resin, the stiffening layer includes polypropylene or a high density polyethylene and the shrink layer includes low density polyethylene. The multilayer films of the present invention have a gloss of at least 62% at 45 degrees, together with a 2% secant tensile modulus greater than 400 MPa.
