Načelo adhezije
The bonding principle of double-sided tape is that a layer of adhesive is coated on its surface. These adhesive molecules form bonds with the molecules of the objects to be connected, thereby firmly bonding the molecules together. The earliest adhesives came from animals and plants, while various polymers are widely used in modern times.
