ABSTRACT:
Methods of making adhesive articles providing air egress by supplying a route for the air to flow out from under the construction are described. One method includes providing a release liner comprising a moldable layer having a release surface and a back surface; applying a first pattern of a first non-adhesive material to a first portion of the release surface; applying a second pattern of a second non-adhesive material to a second portion of the release surface, wherein the second pattern partially overlaps the first pattern; embedding at least one of the first or second non-adhesive materials into the moldable layer, and transferring an adhesive layer having a front and back surface and end edges onto the release liner, wherein the front surface of the adhesive layer is adhered to the release surface of the release liner.
