Duct tape, also known as Cloth Tape or Duck Tape is a cloth-backed pressure-sensitive tape which is often coated with polyethylene. Duct tapes main feature is its strong adhesive capacity and its resistance to water (not waterproof). The construction of different duct tapes varies in the type of backings and adhesives that are used. Our Duct Tapes Guide offers a more complete overview of the different types available on the market.
Duct tape consists of an outer layer of plastic film, usually polyethylene or LDPE (low-density polyethylene) that provides waterproofing and weather resistance. Some tapes have a vinyl outer coating which is resistant to abrasions. Tapes are also available that are made from transparent materials that make them less visible when applied.
The different types of duct tape vary according to the fabric fibres that are used. These fabric fibres can be cotton, nylon, fibreglass, rayon or polyester. The most common widths for duct tape are 48 mm and 51 mm
Originally the silver-grey coloured duct tape was used to seal joints in heating or air conditioning ducts to make them airtight but it now has multiple uses, including holding things together or onto a surface. They're available in a range of materials with different properties and colours enabling them to be used for many tasks - making it an essential item for any DIY tool kit.
