Abstract:
The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.
