  • Patent number: 7744975
    Abstract: A roll of contaminant removal tape defining opposing longitudinal ends, opposing side edges, and opposing major surfaces. The tape is wound into a roll and includes a backing layer, an adhesive layer, a plurality of lines of perforations, and a set of discrete non-adhesive zones. The adhesive layer is applied to a first side of the backing layer to define a portion of the first major surface. The lines of perforations extend across at least most of the width of the tape between the first and second side edges to separate the tape into sheets. The non-adhesive zones are provided along the first major surface of the tape, with each non-adhesive zone extending from the first side edge. In one embodiment, the lines of perforations are progressively longitudinally spaced from one another, and respective ones of the non-adhesive zones correspond with respective ones of the lines of perforations.
