It is also called bopp tape, packaging tape, etc. It is based on BOPP biaxially oriented polypropylene film. After heating, the pressure-sensitive adhesive emulsion is evenly spread to form an adhesive layer ranging from 8μm to 28μm. Form the BOPP tape mother roll, which is a light industry enterprise, public Indispensable supplies in company and personal life, the country does not have a complete standard for the tape industry. There is only one industry standard BOPP pressure-sensitive adhesive tape for sealing. After the BOPP original film is treated with high-voltage corona, one side of the surface becomes rough, and then glue is applied to it to form a tape mother roll, which is then divided into small rolls of different specifications by a slitting machine, which is what we use daily Tape out. Pressure sensitive adhesive emulsion, the main component is butyl ester.   1. Production specifications The specifications of BOPP sealing tape 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 were: 72mm, 60mm, 50mm, 30mm, etc.; nowadays, it has been gradually changed to: 60mm, 48mm, 45mm, 40mm, 30mm, etc.; "Length" is the total length of the tape after it is unwound, 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 the original BOPP film + glue 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 "RMB/square meter" to calculate the price of tape, then "price of each roll of tape = width (m) * length (m) * square price"   2. Main features High-quality and high-performance tapes have good performance even in extremely harsh climates, and are suitable for storing goods in warehouses, shipping containers, and preventing goods theft and illegal opening. Up to 6 colors and different sizes are available. Neutral and personalized sealing tape   3. Scope of application Suitable for general product packaging, sealing and bonding, gift packaging, etc. Color: Various printing tapes can be made according to customer requirements. Transparent sealing tape is suitable for carton packaging, parts fixing, sharp object binding, artistic design, etc.; The color sealing tape provides a variety of color options to meet different appearance and aesthetic requirements; Printing box sealing tape can be used for international trade sealing, express logistics, online shopping, electrical appliances brands, clothing shoes, lighting lamps, furniture and other well-known brands. The use of printing box sealing tape can not only improve the brand image, but also achieve a wide range of And the effect of advertised.
