Generally a pressure sensitive tape does not require a chemical solvent, water or heat for immediate activation. There are also glued or water based adhesive tape that need hot water using them. Similarly, the heat based tapes need heat to activate the tapes. The single-sided pressure sensitive tapes can be stuck to a material’s surface or above the overlapping materials to hold them firmly. Double-sided tapes have adhesives on either sides and can bond two items facing each other.
The pressure sensitive tape originated during 1845 and a surgeon named Horace Day developed them. During the 20th century the tapes for industrial purposes were introduced.
