Adhesive tape is an adhesive-coated fastening tape used for temporary or, in some cases, permanent joining. Single-sided tapes allow joining of two overlapping or adjoining materials, while double-sided tape (adhesive on both sides) allows joining of two items back-to-back.
These tapes are made by applying an adhesive emulsion to a tape or film that is then wound onto a roll. Manufacture often involves winding large films of material onto a roll and then cutting the roll into convenient widths.
Adhesive tape was invented in 1925 by Richard Drew of 3M. The original tape was a paper-backed masking tape. Transparent and other tapes grew from this invention.
