How Do You Judge The Quality Of The Tape?

 how do you judge the quality of the tape?

In fact, there are two standards in the use of glue in adhesive tapes. One is initial adhesion and the other is retention. The two are inversely proportional. Under normal circumstances, the adhesive strength is lower than the number 10 tape is less than the plastic coating, generally only about 20 microns, such as stationery tape, tape for ordinary promotional bundles. The initial adhesive strength of normal sealing tape is between 15-20. The thickness of the tape glue is generally 22-28 microns. It is a standard thickness. However, most of the adhesive tapes on the market are impregnated with impurities, so the thickness is increased to mask the impurities. The glue is also doped with toner, so the scotch tape appears egg-white and pale green. Such tapes are generally inferior.
