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.

Abstract: A single-layer spunbonded air-filtration web including meltspun autogenously bonded electret fibers with an Actual Fiber Diameter of from 3.0 microns to 9.0 microns. The air-filtration web exhibits a mean flow pore size of from 8.0 to 19 microns and exhibits a ratio of mean flow pore size to pore size range of from 0.55 to 2.5. Also disclosed are methods of making such webs, and methods of using such webs to perform air filtration.
