The Identification Of Tape Is A Simple Judgment

1. See the total thickness of the tape.

2. Look at the pull of the tape.

3. Look at the adhesive tape (that is, sticky).

4. Look at the stripping force of the tape. Another way is: to take a piece of tape sealed on the box, to see if it is easy to get up, whether it is easy to pull off, torn can the surface of the carton to destroy ordinary daily life in the sealing tape (Bopp biaxial tensile polypropylene) is any precision steel pipe enterprises, companies, personal life indispensable daily necessities, but compared to the current domestic situation, manufacturers although many, technology is uneven. And the domestic tape industry in the technical content is still in a very low stage, the national fume cabinet has not a clear choice. People often know the tape in a very ignorant stage, that the price is low, feel good viscosity, in fact, these are the wrong understanding and judgment. So how to choose the tape good or bad? In fact, the adhesive tape is good or bad in the use of two of standards, one is the initial adhesion, one is to maintain the force, the two are inversely proportional. Under normal circumstances, the adhesive tape is less than 10th of glue coating, generally only about 20 microns, such as stationery tape, general promotional bundled tape. Normal sealing adhesive tape of the initial adhesion between 15-20, the thickness of this tape glue is generally 22-28 microns. is in accordance with the standard thickness. But the current market of most of the tape has been added to the cold water machine impurities, so the thickness of the increase, to cover impurities, glue also mixed with colored powder, so the transparent tape appears yellow egg, light green, the tape is generally poor. How to distinguish between good and bad for colored tape? For colored tapes, generally yellow and yellow soil more. will be sticky and then quickly opened, you can pull off the side of the plastic, you can see the purity and transparency of the original film. can also look at the thickness of the glue, if no glue is pulled open or point-like, this glue is a large number of impurities, glue is not cohesive. Second, too much water, Wuxi fast food has been volatile, at this time the adhesive tape has dropped very badly, the handle can be distinguished. In fact, the difference between good and bad tape there are many ways, as long as the attention in life, can distinguish the good or bad tape. First go over the water and then scrape it with a knife.
