adhering to material of like nature and is known to those in the
art. The cohesive is typically nonadhesive to dissimilar
materials. These polymers are know[n] as cohesive or
autoadhesive polymers. The cohesive layers are typically a
thermoplastic elastomer material having cohesive properties at
room temperature. The cohesive materials are characterized by
physical cross-links which are labile and therefore may be
rendered ineffective by processing techniques involving the
application of heat.

2. U.S. Patent 3,827,625, issued to Harmon B. Miller ("Miller") is styled
"Reclosable Package and Controlled Release Paper for Use Therein" and
teaches, in the words of the patent, "an improved release paper for pressure
sensitive adhesive which is characterized by an improved ability to adhere to
pressure sensitive adhesive." (Miller at 1:4–7.)
3. An embodiment of Miller's invention is illustrated in Miller Figure 5,
which is shown below:
{Miller Figure 1B is said to depict an embodiment of Miller's invention.}
4. Miller Figure 5 shows a sheet comprising a layer of pressure sensitive
adhesive 12 on a paper base 13 overlying a release sheet comprising a
release layer comprising stripes 5 of a release coating material on a layer 6
of paper; layers 11 and 7 are heat-sealing adhesive layers. (Miller
at 2:48-52 and at 2:54–3:6.)
