Abstract
Abstract An adhesive laminate, including a base web having a coating of pressure-sensitive adhesive and a backing removably adhered to the coating of adhesive for protecting and containing the adhesive, is described. The backing has one or more non-linear, discontinuous score lines formed, preferably, with a laser. A sine-wave, geometric pattern is also preferred. The non-linear, discontinuous score line enables a crack-and-peel feature to be introduced to the laminate backing.
