Duct tape is a type of strong, cloth-backed adhesive tape that is commonly used to repair or seal various objects. The name comes from its original use as a fabric backed with pressure-sensitive rubber-based adhesive, which was designed for sealing and insulating ducts in heating and air conditioning systems.
The term "duct tape" is often used more broadly to refer to any strong, long-lasting tape that can be used for temporary fixes or repairs of various objects such as pipes, furniture, appliances, and even clothing. It has become a popular tool in many different fields due to its versatility and effectiveness.
