US Patent:

53763947, Dec 27, 1994

Filed:

Jan 21, 1994

Appl. No.:

8/184334

Inventors:

Vincent J. Dudenhoeffer - Centerville IA
Jeffrey M. Schuetz - Woodridge IL

Assignee:

Viskase Corporation - Chicago IL

International Classification:

B65B 3102
B65B 5302

US Classification:

426415

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.

Appl. No.:

8/200328

Inventors:

Darrel L. Wilhoit - Joliet IL
Vincent J. Dudenhoeffer - Centerville IA

Assignee:

Viskase Corporation - Chicago IL

International Classification:

B29C 7104

US Classification:

264 22

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.
