Adhesive tape
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 the 3M (Minnesota Mining and Manufacturing) Company. The original tape was a paper-backed masking tape. Transparent and other tapes grew from this invention.
Varieties of Adhesive Tape
- Transparent Tape ("Sticky Tape") like Scotch Tape and Sellotape is cellulose-based and transparent.
- 'Gaffer tape' is normally based on a heavy fabric or plastic tape. The name derives from its use by gaffers in the entertainment industry among others, to hold down cables particularly to obviate or prevent tripping hazard.
- Duct tape (sometimes referred to as "duck tape") has a fabric backing and many uses.
- Masking tape is used to cover areas that shouldn't be painted. It has a paper backing and weak adhesive.
- Electrical tape is made of materials like vinyl that do not conduct electricity.
