Box-sealing tape

Box-sealing tape, parcel tape, packing tape, or shipping 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.

Common packing tape is 50 mm wide, but narrower and wider variants are also common, like for example 36 mm, 48 mm and 72 mm (approx 1.5 in, 2 in and 3 in). A variety of backing strengths and calipers as well as adhesive formulations are available. The thickness of the tape may be in the order of 40 μm for low strength, 45 μm for normal strength, or 50 μm and up for extra strength.

It is often transparent or tan (beige, buff, brown), but can be had in any color with or without prints and logos. The length of a roll varies, but can be around 50-70 meters.
