Abstract

A flexible hook hanger comprises an elongate sheet of pliable backing, an adhesive layer and a hook element. The backing comprises first and second ends, a first zone positioned adjacent the first end, a second zone positioned adjacent the second end and a central zone positioned between the first and second zones. The adhesive layer is disposed on one side of the backing. The hook element is connected to the central zone. In one embodiment, the pliable backing comprises microstructured tape, and the adhesive layer comprises a pressure sensitive adhesive composition comprising one or more hydrocarbon block copolymers, and a polar phenolic tackifier. In another embodiment, at least one of the first and second zones includes a peel arrestor. For example, the first zone and the second zone have a first width and a second width, respectively, and the central zone has a third width that is less than at least one of the first width and the second width.
