Abstract: An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene) copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear.

Abstract: A stretch releasing pressure-sensitive adhesive article that includes a backing that includes a layer of foam having a density of from about 7 pounds per cubic foot to about 15 pounds per cubic foot, a caliper of from about 0.01 inch to less than 0.020 inch, a first major surface and a second major surface opposite the first major surface, a first pressure-sensitive adhesive composition disposed on the first major surface of the layer of foam and in direct contact with the layer of foam. The article exhibits at least about 40% surface contact to a standardized textured surface.
