Claims 10 through 35 stand rejected under 35 U.S.C. § 103

lower surface polyolefin having a coating of (A) a resin where

friction of the polyolefin (independent claim 23, see Figure

liner (see independent claim 10 and Figure 2); or (C) a
pressure-sensitive adhesive and a release-coated liner
laminate (see independent claim 29).
