  • Process of corona treating a thermoplastic tubular film
    Patent number: 5407611
    Abstract: A meat product package including an enclosing film having an EVA-containing inside surface and an in situ aqueous medium-cooked meat product in adhering relation to the film inside surface as the meat contacting and adhering surface. Starch particles are preferably dispersed across the meat contacting surface which has been both irradiated and subjected to corona treatment. A method for corona treating a thermoplastic tube inside surface in which small particles within the flat tube separate opposite surfaces providing voids, and the electric discharge crosses the flat tube through the voids.
    Type: Grant
    Filed: February 23, 1994
    Date of Patent: April 18, 1995
    Assignee: Viskase Corporation
    Inventors: Darrel L. Wilhoit, Vincent J. Dudenhoeffer
  • Bone-in food packaging article and use field of the invention
    Patent number: 5376394
    Abstract: A method for shrink packaging bone-in food masses such as meat cuts is disclosed, A patch bag comprising a thin-walled heat shrinkable thermoplastic film bag and a thick-walled non-heat shrinkable thermoplastic film patch having its inner surface bonded to the bag outer surface is used. Both surfaces have high energy as the sole bonding means and the patch-bag bond strength increases during heat shrinking around the meat mass such that the bag portion adhered to the patch shrinks less than the rest of the bag.
    Type: Grant
    Filed: January 21, 1994
    Date of Patent: December 27, 1994
    Assignee: Viskase Corporation
    Inventors: Vincent J. Dudenhoeffer, Jeffrey M. Schuetz
