Abstract of the Disclosure A biaxially stretch-oriented film, suitable for the process of transfer metallizing, which comprises a base layer coextruded with covering layers on either side thereof and comprising an inert admixture is disclosed. The three layers are formed of polyolefin and the base layer comprises an additive which migrates from the base layer into the covering layers. The base layer contains the inert admixture in the form of finely divided particles, which partially protrude from the base layer and are completely enveloped by the covering layers. At least one of the two outer surfaces of the covering layers displays, at least in partial areas, an increased roughness attributable to the particles protruding from the base layer.
