The method to determine whether the quality of the seal printing tape is poor:
Ordinary sealing tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance. The activity will be affected by the level of temperature. Tincture content of glue will directly affect the use of tape. Some individuals think that sticky tape has good glue, in fact, this is wrong. Adhesive tape in the use of good or bad there are two standards, one is the initial sticky force, one is to maintain. The two are inversely proportional. Generally speaking, the initial adhesion of less than 10 of the tape is coated with glue less, only about 20 microns, such as stationery tape, the general promotion of bundled tape. Normal initial adhesion of the sealing tape is between 15 and 20, the thickness of this tape glue generally 22-28 microns. It is in line with the standard thickness. But most of the tapes on the market are now mixed with impurities, and the thickness increase. To cover impurities, glue also mixed with toner, and transparent tape appears egg yolk, light green.
