Pressure-sensitive tape Edit
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 to surfaces with light pressure. Typical adhesives are polymers such as acrylates, natural, and synthetic rubber. 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 Edit
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.
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 3 inch or 7,5 cm wide.
Heat-sensitive tape Edit
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 is particularly useful in the semiconductor industry.
Drywall tape Edit
