Duct tape or duck tape is cloth- or scrim-backed pressure-sensitive tape often coated with polyethylene. There are a variety of constructions using different backings and adhesives. One variation is gaffer tape designed to be cleanly removed, while duct tape is not. Another variation is heat-resistant duct tape useful for sealing heating/ventilation/air-conditioning (HVAC) ducts, produced because standard duct tape fails quickly when used on heating ducts. Duct tape is generally gray or black but also available in other colors.

During World War II, Revolite, then a division of Johnson & Johnson developed an adhesive tape made from a rubber-based adhesive applied to a durable duck cloth backing. This tape resisted water and was used as sealing tape on some ammunition cases during that period.
