Ordinary sealing and packaging tapes in daily life are indispensable daily necessities in any business, company or personal life. People often know the tape at a very ignorant stage. They think that the price is low and the viscosity is good. In fact, these are misunderstandings and judgments.
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, which is 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, tape for general promotion bundle. The normal adhesive tape has an initial tack of between 15 and 20 and the tape typically has a thickness of 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.
