ABSTRACT:
A biaxially oriented multilayer film usable to form adhesive labels to be attached to containers, such as bottles and cans. The film includes a core layer comprising polypropylene and a migratory slip agent and an outer slip layer on one side of the core layer. The slip layer includes primarily polypropylene, by weight, and a minor percent, by weight, of an additive, with the additive and the migratory amide being present in amounts to provide a COF on the surface of the slip layer of no greater than 0.45 and to provide an adhesion of the adhesive employed on the formed label for the slip layer of at least 50%.
