ABSTRACT:
The disclosed oriented, multilayer olefin polymer film comprises an olefin polymer base layer and at least one outer layer, which outer layer contains from 0.01 to 1% by weight, based on the weight of the outer layer, of approximately spherical ceramic particles. The outer layer can be heat-sealable or non-heat-sealable. The multilayer olefin polymer film is produced by a coextrusion process in which the coextruded film is biaxially stretched, heat-set, and optionally surface-treated. The resulting film is useful in packaging and as a printing surface or in laminates.
