Filament tape or strapping tape is a pressure sensitive tape used for several packaging functions such as closing corrugated fiberboard boxes, reinforcing packages, bundling items, pallet unitizing, etc. It consists of a pressure sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film and fiberglass filaments embedded to add high tensile strength.
Most often, the tape is 12 mm (aprox 1/2 inch) to 24 mm (aprox 1 inch) wide but is also used in other widths.
A variety of strengths, calipers, and adhesive formulations are available.
- 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.
- The tape can be applied manually with a stationary dispenser but is more often applied with a hand held tape dispenser: 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.
- For heavy duty packaging
- For sealing HR coil
- For sealing heavy weight boxes or objects
- Many sizes
- Many grades
