. Several other varieties have since been developed. A variety of grades of filament tape are available. Some have as much as 600 pounds of tensile strength per inch of width (100 N/mm). Different types and grades of adhesive are also available. Most often, the tape is 12 mm (approx. 1/2 inch) to 24 mm (approx. 1 inch) wide, but it is also used in other widths. A variety of strengths, calipers, and adhesive formulations are available.

Uses

The tape is most often used as a closure for corrugated boxes such as a full overlap box, five panel folder, full telescope box. "L" shaped clips or strips are applied over the overlapping flap, extending 50 - 75 mm (2 - 3 inches) onto the box panels. Heavy loads or weak box construction may also be aided by the application of strips or bands of filament tape to the box.

Application

The tape can be applied manually with a stationary dispenser but is more often applied with a hand held

: this allows the user to more efficiently place the tape on the box, cut it off, and rub it down. Automated machinery for application of tape to high speed lines is also common.

Some PSA tapes are available which have a highly oriented
