What Is Adhesive Tape?

- Sep 07, 2017 -

Adhesive tape is a variety of combinations backing materials coated with an adhesive. Different backing materials and adhesives can be used depending on the intended use.


Now in market we used adhesive tapes have 4 different adhesive tapes as following:


1. Pressure-sensitive 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 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.


2.Water activated tape

Water activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a kraft paper backing which becomes sticky when moistened.


A specific type of gummed tape is called reinforced gummed tape (RGT). The backing of this reinforced tape consists of two layers of paper with a cross-pattern of fiberglass filaments laminated between. The laminating adhesive had previously been asphalt but now is more commonly a hot-melt atactic polypropylene.


3.Heat sensitive tape

Heat activated tape is usually tack-free until it is activated by a heat source. It is sometimes used in packaging, for example, a tear strip tape for cigarette packs. Conversely, thermal release tape, such as REVALPHA by Nitto Denko, loses its tack and fully releases when heated to a certain temperature. This type of tape is used often in the semiconductor industry.[citation needed]


4.Drywall tape

Drywall tape is paper, cloth, or mesh, sometimes with a gummed or pressure-sensitive adhesive. It is used to make the joints between sheets of drywall materials.
