Abstract
A laminated film structure that includes a primary web having a migratory additive in a first outer layer and a metallocene polyethylene in a second outer layer that can be laminated to a secondary web without treating the surface of the second outer layer with a primer or solvent. The primary web further includes a core substrate layer disposed between the two outer layers that can include a biaxially oriented polypropylene. The laminated film structures have improved bond strength between the primary web and the secondary web.
