Why is Scotch tape sticky?

There are many kinds of products in the wholesale market of adhesive tape, which can be used in the bonding of various items. Why is it sticky? Let's take a closer look at it now.

The adhesiveness of the product is caused by applying a layer of glue of a specific thickness to the film, and its viscosity depends on the quality of the glue. The fluid and soft glue binds and infiltrates the object to be adhered to so that the molecules of the two are very close to each other. When the two molecules are close enough to each other, there is a mutual attraction between them and they stick together. To put it bluntly, a chemical reaction occurs between the glue and the surface of the object to adhere, so that the molecules at the bonding interface are integrated into one.

Tape is a very good tool, which facilitates our life, so we should also pay attention to the influence of ambient temperature on glue when using it, and store it in a dry and cool environment when not in use. Also, keep away from heat sources and corrosive products such as acid and alkali.
