Patent ID: 7972670

Claim:
A structured paper release liner for use with an article backed with a pressure sensitive adhesive, said liner comprising: a piece of paper comprising fibers and having a release side free of a structural support layer, a back side, and a structured release surface having a pattern formed into, so as to deform the fibers of, said paper on said release side; and a release material bonded so as to contact, and follow the pattern formed into, said structured release surface of said paper, wherein said release material does not form a structural support layer, and wherein the pattern formed in said paper is dimensioned so as to form fluid egress channels in a bonding surface of the pressure sensitive adhesive, when the pressure sensitive adhesive is applied to said structured release surface or said structured release surface is forced into the bonding surface of the pressure sensitive adhesive, such that the fluid egress channels define a structured bonding surface having exit pathways for at least some of the fluid to bleed out from behind the article when the article is adhered to a substrate.
