Abstract
An adhesive tape includes an elongated substrate with a series of perforations forming a tear line extending along a length of the elongated substrate, an adhesive substantially covering a first surface of the elongated substrate, and a cord attached to the elongated substrate by the adhesive, the cord extending along the length of the elongated substrate adjacent to the series of perforations.

Adhesive tape comprising:
- an elongated substrate with a series of perforations forming a tear line extending along a length of the elongated substrate;
- an adhesive substantially covering a first surface of the elongated substrate;
- and
- a cord attached to the elongated substrate by the adhesive, the cord extending along the length of the elongated substrate adjacent to the series of perforations,
- wherein the tear line formed by the series of perforations is an undulating tear line,
- wherein the undulating tear line crosses back and forth over the cord,
- wherein the elongated substrate includes a reduced thickness adjacent to the cord, and
- wherein the reduced thickness is no greater than 75 percent of a thickness of the elongated substrate in areas not adjacent to the cord.
