Abstract
A metallized biaxially oriented film has at least one polypropylene layer and a metallized skin layer. This skin layer is formed from a blend of polymers including syndiotactic polypropylene. The polymer which is blended with the syndiotactic polypropylene may be a butylene-propylene copolymer or a graft copolymer of propylene and maleic anhydride. The film may include a separate non-metallized biaxially oriented film laminated to the metallized biaxially oriented film. The metal layer provides a barrier to oxygen and water vapor. The metallized film can be processed through package forming machines without damage to the metal barrier layer.
