What is Adhesive tape
Adhesive tape refers to any one of a variety of combinations of backing materials coated with an adhesive. Different backing materials and adhesives can be used depending on the intended use.
History
Pressure-sensitive adhesive (PSA), a key component of some adhesive tapes, was first developed in 1845 by Dr. Horace Day, a surgeon.[1] In 1901, the German Oscar Troplowitz invented an adhesive patch called Leukoplast for the German company Beiersdorf AG. In 1936, German company Beiersdorf AG invented a transparent adhesive patch called Tesa
Adhesive strength versus shape
Adhesiveness depends not only on the type of tape but also on its macroscopic shape. Tapes with sharp corners start to detach at pointed corners. Adhesive strength can be improved by rounding the corners.

Duct Tape
Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure-sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or solvent for activation and adheres with light pressure. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term “adhesive tape” is used for these tapes.
Many pressure-sensitive adhesive tapes exhibit triboluminescence, observable in a dark room, when peeled off a dispenser roll or other surface.
