What's in a Name, Duct Tape

It was invented by Johnson & Johnson during World War II. Their original creation for the United States military was a green waterproof tape that could be used for sealing ammunition cases to keep water out.
Soldiers soon learned the tape was good at fixing any type of rip or tear they might encounter for tents, vehicle seats, and even uniforms. After the war, returning soldiers introduced it to friends and neighbors back home.
One of the first uses for the tape was to repair or seal the ductwork in home heating and cooling systems. To match the color of ductwork, the company changed the color of the tape to silver and began to call it duct tape.
Many people believe that the tape was called duck tape, because its ability to repel water reminded of the similar property of duck feathers. There is a brand of tape named Duck tape that is sometimes confused with the original.


Duct tape comes in many different colors, although the most popular are silver and black. It is so strong, because it is made of three different layers. The bottom layer is a strong rubber-based adhesive. The middle layer is a web of cloth fabric that adds durability. The top layer is soft, waterproof plastic.
