How To Distinguish The Quality Of The Tape

So how do you choose the quality of the tape? In fact, the glue of the tape has two standards in use. One is the initial adhesion and the other is the retention force. The two are inversely proportional. Under normal circumstances, the adhesive tape with a viscosity lower than 10 is less adhesive coating, generally only about 20 microns, such as stationery tape, the tape used for general promotion. The initial adhesive strength of normal sealing tape is between 15-20. The thickness of this tape glue is generally 22-28 microns. Is the thickness that meets the standard. However, most of the tape on the market is mixed with impurities, so the thickness is increased. In order to shield the impurities, the glue is also mixed with toner, so the transparent tape appears egg yellow and light green, and the tape is generally inferior.


How do you distinguish between colored tapes? For colored tapes, there are usually more yellows and khakis. By pinching the adhesive and then pulling it open quickly, the rubber can be pulled off and the purity and transparency of the original film can be seen. You can also look at the thickness of the glue. If there is no glue to be pulled apart or pulled apart, there is a lot of impurities in the glue, and the glue has no cohesion. Second, the water is too much and has evaporated. At this time, the initial adhesion of the tape has dropped drastically, and the feel can be distinguished. In fact, there are many ways to distinguish between good and bad tapes. As long as you pay more attention to your life, you can tell whether the tape is good or bad.
