Tapes

Adhesive tapes 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.

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.

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.

Water-activated tape is used for closing and sealing boxes. Before closing corrugated fiberboard boxes, the tape is wetted or remoistened, activated by water. The tape is mostly 7.5 cm wide.

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. This type of tape is used often in the semiconductor industry.
