Abstract
A narrow tape of polyester or other suitable plastic for use as a tear tape in the packaging industry slit from a wide web of the material, is coated wholly on one side and preferably at the edges with a suitable release material. Downstream of the slitting the tape is printed on the other side, then coated over the printing with a suitable pressure sensitive adhesive, said coating width being narrower than the width of the tape covering the printing and spaced from both side edges of the tape to avoid pick-off onto tape guide surfaces. The tape is then wound onto a core with both radial and axial traversing movements. The tape is then supplied to the packaging line preformed with adhesive to avoid on-line adhesive applications.
