Abstract
A structured paper release liner () for use with an article () backed with a pressure sensitive adhesive, an adhesive-backed article assembly () and methods of making each are disclosed. The liner () comprises a piece of paper () having a release side free of a structural support layer, a back side, and a structured release surface () having a pattern formed into the paper () on the release side. A release material is on the structured release surface of the paper. The pattern formed in the paper () is designed so as to form fluid egress channels in a bonding surface of the pressure sensitive adhesive (). The fluid egress channels define a structured bonding surface () having exit pathways for fluid to bleed out from behind the article when the structured bonding surface () is adhered to or otherwise disposed on a substrate.
