The present disclosure provides an adhesive assemblies such as an adhesive assembly for mounting an object to a surface, the assembly comprising: a first adhesive construction including a first major surface and a second major surface, the first adhesive construction including a first adhesive layer, a first core adjacent to the first adhesive layer, the core comprising core material and including first and second major surfaces; and a first arranged pattern of recesses on at least the first major surface of the first core, each recess terminating in a membrane, wherein the membrane is defined by a bottom surface of the recess and comprises core material; and a first adhesive interface at the bottom surface or within the membrane; and a stiffening carrier laminated to the second major surface of the first adhesive construction, the stiffening carrier having a higher stiffness than the first adhesive construction.

Adhesive assemblies permitting enhanced weight bearing performance with damage free removal

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.
