Abstract
Disclosed is a method and apparatus for separately coextruding dissimilar polymer melts through a die, expanding the polymer melts to different degrees and then contacting and adhering the polymer melts together at or near the frost line to produce a laminated film where the various polymer layers thereof can be optimally molecularly oriented in the completed film. The invention is particularly useful in producing a film where one of the extruded layers therein is a polymer foam.
