Abstract
Polymeric, oriented films can be made by the use of a combination of a hot blown process and a blown bubble process. Styrene butadiene copolymer (SBC) forms two outer layers of the preferred embodiment, with a core layer of very low density polyethylene (VLDPE) or blends thereof, and intermediate polymeric adhesive layers such as ethylene vinyl acetate copolymer (EVA) bonding the core layer to the outer layers. A monoaxially or biaxially oriented film is produced with excellent optics.
