Duct tape was invented during World War II in 1942 by Johnson & Johnson's Revolite division. The invention was a result of a request from the U.S. military for a durable, waterproof tape to seal ammunition cases. The tape was designed to keep moisture out and ensure that ammunition would remain dry and functional in harsh conditions. The original product was made using a rubber-based adhesive applied to a durable, waterproof cloth backing.

The tape was initially called "duck tape" due to its water-repellent properties, similar to a duck's feathers. It was also easy to tear into strips by hand, making it practical for soldiers to use in the field. After the war, its versatility and strength led to its adaptation for various civilian uses, including in the construction industry where it became known as "duct tape" because it was often used to seal heating and air conditioning ducts.
