A stretch releasing adhesive tape article includes an elongate length of stretch releasing adhesive tape and a segmented liner arranged on the adhesive that can be used to form a manually engageable pull tab at a selected location on a discrete strip of tape cut from the length of tape. Each segment of the liner can be individually removed from the tape. The segmented liner allows the adhesive tape to be made in any length and wound upon itself to form a roll, and allows a user to cut a strip having a selected length depending on the end use application for the strip, and further allows the user to form a manually engageable non-adhesive pull tab at any location on the strip which can be grasped and pulled by a user to stretch remove the tape from a substrate.
