Tapes

Box-sealing tape, parcel tape or packing tape is a pressure-sensitive tape used for closing or sealing corrugated fiberboard boxes. It consists of a pressure-sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film which is oriented to have strength in both the long (machine) direction and the cross direction.

Uses

The Allentown , PA tape is most often used as a closure for regular slotted containers (RSCs). A “single strip” or “center seam” closure is applied over the center seams of a box extending 50–75 mm (2–3 inches) onto the end panels.

The Allentown , PA tape can be used as a “six-strip” closure or “H-seal” by applying cross strips on the ends of the box. This is used when a relatively weak tape is used or when extra box reinforcement is needed. This method also seals the box to help keep contaminants out.

This Allentown , PA tape has also been used by artists (E.g.Mark Jenkins) as a way to create molds of objects, as the strength of the tape allows for a strong shell for the mold when completed.

Application

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.
