Everything is a good thing or a bad thing, and the same is true when it comes to wholesale tape. Now, I will help you all analyze the lower sealing tape and hope to help you later in life.

Ordinary sealing tape glue is acrylic glue, the main component is tincture. Tincture is a polymeric active substance. Temperature has a certain influence on molecular activity. The tincture content of the glue directly affects the use of the tape. Many people think that tape is good for glue, in fact, this is wrong. There are two standards for tape glue: one is initial adhesion and the other is holding power. The two are inversely proportional. Generally, tapes with a viscosity of less than 10 are less adhesive coatings, usually only about 20 microns, such as stationery tapes, general purpose bundles sell such tapes, common sealing tapes have an initial bond strength of 15 to 20, the The thickness of the adhesive tape is usually 22 to 28 microns which is a standard thickness.

However, most of the tapes on the market will increase in thickness. In this way, the impurities in the tape will be masked, and the toner will also be mixed in the glue, so the poor quality Scotch tape will appear egg-yellow and light green, and the plastic tape quality of the tape will be Usually poor.
