wherein the rear edge is opposite the front edge; and
wherein the first, second, third and fourth planes intersect each other at a discrete point and which point forms an uppermost tip of the tooth; and
wherein a length of the central rear edge is shorter than a length of the central front edge;
providing a rotational element including a length of Biaxially-Oriented Polypropylene (BOPP) BOPP tape;
engaging the rotational element in the dispenser so that the rotational element is located between the interior surfaces of the first and second sides and rearwardly of the cutter assembly and so that the rotational element is rotatable about an axis extending at right angles to the interior surfaces;
withdrawing a length of tape from the rotational element by rotating the rotational element around the axis;
applying a braking mechanism to the rotating rotational element; and
slowing or stopping rotation of the rotational element andsevering a desired length of the (BOPP) tape using the row of plastic teeth on the cutter assembly.

Abstract
A cutter assembly suitable for cutting BOPP adhesive tape and a tape dispenser incorporating the same. The cutter assembly has a row of plastic teeth where each tooth includes left and right front and rear faces, each face being disposed on a different plane, and where the planes intersect each other at the tip of the tooth. A front edge extends between the left and right front faces; a rear edge extends between the left and right rear faces; a left side edge extends between the right front and rear faces; and a right side edge extends between the left front face and the right rear face. The various edges are set at particular angles relative to each other. A protrusion for supporting the tape is provided rearwardly of the teeth and a braking mechanism is also provided on the dispenser.
