Pressure-sensitive adhesives (PSA) are physically hardening systems which are characterized by a permanent tackiness.

Bonds are made by applying pressure on the adhesive film - the more pressure is applied, the better is the adhesion.

Single-sided tape possesses the adhesive backing on only one side, which can be made of a variety of web-based materials, such as film, paper, foil, fabrics, or foam.

The top of the backing’s release coating exists to make the tape easier to handle and unwind.

Meanwhile, the bottom of the backing is coated with a primer to ensure the adhesive layer bonds to a target material.

For their usages, single-sided tapes are used in athletic tape, HVAC applications, electrical tape, medical bandages, surface protection/patching and more.
