It is a pressure-sensitive tape for office use. . It consists of a pressure-sensitive adhesive coated onto a backing material i.e: polypropylene which is a thermoplastic polymer (making it pliable above a certain temperature, and returning it to the solid state after cooling). Most often the Packing tapes are bi-axially oriented which is a PP film stretched to the machine and cross direction which increases the strength as well as the clarity of the film. The structure also makes the automated and manual application of the packing tape easier.
Due to it being a thermoplastic polymer, it could also work in higher and lower temperatures. Not all manufacturers provide tensile strength statistics but industrial grade packing tape should be able to bear longitudinal pressure of around 27 pounds per inch and 44 lbs. per inch, transverse.
Its structure being rugged and high tensile makes it an ideal material for packaging and labeling. It is also resistant to abrasion, moisture and various chemical solvents. It is easy to coat, print and even to laminate, which makes it ideal for the manufacture of custom packaging tape. The material also offers minimal elongation (only around 150%, on average), and is burst-resistant making it easy to slit. The average application temperature range for 30-micron, standard thickness BOPP packaging tapes is between 35 and 110 degrees F while the operating temperature range is at 20 to 150 degrees F.
The tape is normally slitted to 12 mm width (approx 0.5 inches)
Like the Bopp packing tape, its properties are same, but the Inner core is made of Plastic instead of Paper and the Inner Diameter of the tape is 1 Inch. It often comes in one dozen packing.
