Overview
Tape is a long, narrow strip of flexible material, often supplied in rolled form for convenient dispensing. It may be adhesive on one or both faces, non‑adhesive, magnetic, or carry other functional layers. For basic definitions and further resources see more.
Characteristics and construction
Most tapes combine three elements: a backing (paper, cloth, plastic film, metal foil or fabric), a functional layer (adhesive, magnetic coating or printed markings), and sometimes a release liner. Adhesives vary—rubber, acrylic or silicone—giving tapes different tack, temperature tolerance and residue behavior.
History and development
Strips of adhesive substances have been used for centuries, but modern pressure‑sensitive tapes emerged in the early 20th century as flexible plastics and adhesives improved. Notable commercial advances include cellophane and early transparent adhesive tapes and later durable cloth and foil products developed for industrial and military use.
Major types
- Adhesive tapes: masking, duct, electrical, packing, double‑sided.
- Specialty tapes: medical (surgical), heat‑resistant, anti‑slip.
- Non‑adhesive tapes: measuring tapes and tapes used for binding or decoration.
- Data and magnetic tapes: for recording audio, video and computer data.
Each type is engineered for particular properties: tensile strength, conformability, dielectric performance or archival stability.
Uses, importance and distinctions
Tape is ubiquitous: packaging and shipping, temporary masking in painting, electrical insulation, emergency repairs, medical dressings, and data storage. It is distinct from ribbon or film by its narrow width and roll format. Environmental concerns have driven interest in recyclable backings and low‑residue adhesives; disposal and recycling depend on materials and local facilities.
