发明名称 Progressively perforated tape roll
摘要 A tape includes a backing layer and an adhesive layer formed on the backing layer. A plurality of lines of perforations extend across the tape to separate the tape into sheets. The sheets have progressively increasing lengths such that, when the sheets are wound into a roll, each sheet is longer than the sheet underneath it. When in a roll, the outermost sheet covers all of the lines of perforations to reduce instances of the tape tearing in a downweb direction.
