The adhesion property of the adhesive itself and the good wetting property to the surface of the adhesive are the adhesion characteristics that are sensitive to external pressure with the adhesive tape. However, this adhesion feature of the pressure sensitive adhesive tape can also be quantitatively characterized by a number of applicable adhesion functions that can be tested.

These applicable adhesion functions are: back force T, adhesion force A, cohesion force. C, and bonding force K. For a suitable pressure sensitive adhesive tape, the following requirements must be satisfied between these functions: initial adhesion is also called fast adhesion. It refers to the ability to distinguish between the pressure sensitive adhesive surface and the surface of the adhesive with very light pressure, and immediately leave the resistance displayed. Ordinary is the so-called finger when quietly touch the pressure sensitive adhesive surface and immediately remove the hand's adhesion. This is the pressure sensitive adhesive tape unique to a suitable adhesive function.
