Duct tape

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 and ventilation (HVAC) ducts, produced because standard duct tape fails quickly when used on heating ducts.
