Ordinary sealing tape glue is acrylic glue, also called pressure-sensitive adhesive, the main component is tincture. The tincture content of the glue directly affects the use of the tape. Many people think that the sticky tape is good for glue. In fact, this is wrong. There are two criteria for the quality of adhesive tape in use, one is the initial adhesion, the other is the retention, and the two are inversely proportional.
Generally speaking, adhesive tapes with initial adhesion lower than No. 10 are less glued. However, most of the tapes on the market are mixed with impurities, so the thickness increases. In order to hide the impurities, the glue is also mixed with toner, so it is transparent. The tape appears egg-yellow and light green. This kind of tape is generally inferior. The quality of the glue and film determines the quality of the tape. Only by choosing a good glue and film can a good tape be produced.
