  • Thermoplastic Film Structures with a Low Melting Point Outer Layer
    Publication number: 20090202848
    Abstract: A film structure including at least a base layer containing a thermoplastic polymer and at least an outer layer containing a low melting point polymer. Methods of manufacturing the film structure, including the steps of coextruding melts corresponding to the individual layers of the film structure through a die and thereafter: simultaneously biaxially stretching the coextruded film sheet; or sequentially biaxially stretching the coextruded film sheet, wherein the machine-direction orientation (MDO) is performed with a radiant-heated MDO stretcher. An extrusion-coated film structure exhibiting strong bond adhesion, and a method of manufacturing the same are also provided.
    Type: Application
    Filed: April 16, 2009
    Publication date: August 13, 2009
    Inventors: Pang-Chia Lu, Robert G. Peet, Benoit Ambroise, Linda Maria Van den Bossche, Nancy Vanderheyden, Francois Bosch, Jacques Moriau, Lindsay J. Mendes, Syd R. Wright
