A refastenable adhesive closure is provided. The closure has a pressure-sensitive adhesive-bearing fastening tab and a target portion, or target strip, having a working face for contact with the adhesive-bearing fastening tab. The working face of the target strip is formed with peaks and valleys, the height of the peaks above the valleys being substantially uniform and from about 40 to 300 .mu.m, the spacing between adjacent peaks being from about 50 to 500 .mu.m, the back face of the target portion being substantially flat, and the thickness of the adhesive layer of the tab being no more than about 90% of the height of the peaks above the valleys. The closure is resistant to contamination by dust and other fine particulate matter and is especially useful for refastenable disposable diaper closures and refastenable envelope closures.
