Pressure sensitive tape, PSA tape, Adhesive tape, Self stick tape, Sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. Some have a removable liner which protects the adhesive until the liner is removed. Some have layers of adhesives, primers, easy release materials, filaments, printing, etc. made for specific functions.
 
  Pressure sensitive tape will stick with application pressure without the need for solvent, heat, or water for activation. By contrast a "gummed" or "water activated" tape requires warm water for activation. Likewise, some "heat activated" tapes require heat.
 
  PSA tape is used in the home, office, industry, and institutions for a wide variety of purposes. Single-sided tapes allow bonding to a surface or joining of two adjacent or overlapping materials. Double-sided tape (adhesive on both sides) allows joining of two items back-to-back.
