How to Distinguish the Quality of Bopp Carton Sealing Tape?

Bopp carton sealing tape is an indispensable daily product for any company, unit, individual and family. However, there are many BOPP film roll manufacturers, but the technology is uneven. 


Everyone knows a little about BOPP film roll. They think that low price and good hand feel viscosity mean good tape quality. How to distinguish the quality of BOPP packaging tape?


Ⅰ. The standard for measuring the quality of the glue of BOPP packaging tape


One of the standards used is the initial adhesion force and the other is the persistence force, which are inversely proportional. Generally, BOPP packaging tape with adhesive force lower than No.10 is considered not thick enough. The initial adhesion of normal carton sealing tape is between No.15-20. The thickness of this tape glue is generally 22-28 microns. This is the standard thickness. However, most of the tapes on the market are mixed with impurities, so the thickness is increased to cover up the impurities. The glue is also mixed with toner, so there are light yellow and light green transparent tapes. This kind of tape is generally of poor quality.


Ⅱ. How to distinguish the good and bad of colored bopp packaging tape


As for colored packaging tape, yellow and earthy yellow are more common. Pinch the adhesive tape tightly, and then quickly pull it apart. If you can pull the glue off one side, you can see the purity and transparency of the original film of the carton sealing tape and the thickness of the glue. If no glue is placed or dotted, there are many impurities in the glue, and the glue has no cohesion. 


Second, there is too much water, which is now transpiration. At this time, the initial adhesion of this kind of tape has decreased, which can be distinguished by hand feeling. In fact, there are many ways to distinguish between good and bad tapes. You can distinguish good and bad tapes only by understanding them on the spot.
