Appeal No. 1997-3611
Application No. 08/439,414
U.S. Patent 5,242,650 issued to Rackovan on September 7,
1993 (hereinafter “Rackovan”) is directed to an in-mold
labeling process and in-mold labeled articles, wherein a label
film to be employed, comprising a face layer 12, a core layer
16 and a heat-activatable adhesive (base) layer 14, is
coextruded and then hot-stretched to avoid shrinking, relaxing
or any distortion of the film which may interfere with the in-
mold labeling process. See Rackovan, column 4, lines 6-27,
and column 5, line 11. Rackovan also refers to US. Patent
4,837,075 issued to Dudley on June 6, 1989, which discloses an
in-mold labeling process involving the use of polymeric label
stock in the form of a multilayer coextrudate comprising a
layer of heat-activatable adhesive. See Rackovan, column 3,
lines 25-42. Although both Rackovan and Dudley do not appear
to describe forming coextruded films having therebetween a
peelable interface, Freedman does teach that the formation of
such films having a peelable interface advantageously provides
“renewable surfaces” for manufactured products as indicated
supra.
