BOPP Self Adhesive Tapes-Plain

BOPP Self Adhesive Tapes-Plain 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. BOPP Self Adhesive Tapes, 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.
The adhesiveness of the tape does depend not only on the type of the tape but also on its macroscopic shape. Tapes with sharp corners start to detach at pointed corners. The adhesive strength can be sufficiently improved by cutting the edges as shown in the film.
