Also known as the sealing tape mother roll, the packaging tape mother roll, etc., it is based on BOPP biaxially oriented polypropylene film as a substrate, and is uniformly coated with a pressure-sensitive adhesive emulsion to form 8 μm----28 μm. The rubber layer is an indispensable item in light industrial enterprises, companies and personal life. The country does not have a perfect standard for the tape industry. There is only one industry standard "QB/T 2422-1998 sealing with BOPP pressure sensitive adhesive. After the high pressure corona treatment of the BOPP original film, the surface of the BOPP is rough, and the glue is applied to the top to form the parent roll, which is then cut into small rolls of different specifications by the slitting machine, which is our daily use. The tape is gone. Pressure sensitive adhesive emulsion, the main component is butyl ester.
   Production specifications: BOPP tape mother roll specifications are expressed by "width × length × thickness", where "width" is the width of the tape, generally expressed in mm or cm, generally ≥ 10mm, as early as the 1980s, common specifications are: 72mm , 60mm, 50mm, 30mm, etc.; nowadays, has gradually changed to: 60mm, 48mm, 45mm, 40mm, 30mm, etc.; "long" is the total length after the tape is opened, generally expressed by "m" or "code" ( 1 yard = 0.9144m), common lengths are 50m, 100m, 150m, 200m, 500m, etc.; thickness refers to the total thickness of BOPP original film + adhesive layer (unit: micron, μm), commonly used 45 ~ 55μm. Such as "50mm × 100m × 50μm"
  The calculation method of the unit price of each roll of tape: the tape industry usually uses “yuan/square meter” to calculate the price of the tape, then “price per tape = width (m) * length (m) * square price”
  Main features: High-quality and high-performance tapes perform well even in extreme weather conditions, suitable for storage in warehouses, shipment of containers, and prevention of goods theft, illegal opening, etc. Supply up to 6 colors and different Neutral and personalized sealing tape in the form of dimensions
  characteristic:
Instant Adhesive Force - The sealing tape is sticky.
Fixing ability - even with very little pressure, it can be glued to the workpiece according to your ideas.
Easy to tear - easy to tear off the tape without the tape stretching and dragging.
Controlled deployment - the sealing tape can be pulled away from the tape in a controlled manner, neither too loose nor too tight.
Flexibility - The sealing tape can be easily adapted to sharp curves.
Thin – the sealing tape strip does not leave thick edge deposits.
Smoothness - The sealing tape feels smooth and does not irritate the hands when pressed.
Anti-transfer - no adhesive will be left after the sealing tape is removed.
Anti-solvent - The backing material of the sealing tape prevents solvent penetration.
Resistance to chipping - the sealing tape does not have cracks.
Anti-retraction - the sealing tape can stretch along the curved surface without retraction.
Anti-stripping - the paint will be fastened to the backing of the sealing tape.
