Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...

Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
The adhesive is coated onto a flexible material (the backing) such as paper, foil, fabric, or plastic film (such as biaxially oriented polypropylene or polyvinyl chloride [6] [9]) to provide strength and protect the adhesive from degradation by environmental factors including humidity, temperature, and ultraviolet light. Backing tensile ...
