Duct tape is composed of three layers.  The top layer is a plastic, polyethelyne; the middle layer is a fabric mesh; the bottom layer is a rubber-based, pressure sensitive adhesive.  It was originally manufactured simply by pressing these three layers together and was named “Duck Tape”, not “Duct Tape”.   It was invented by Johnson & Johnson’s Permacel division during WWII for the military.  The military specifically needed a waterproof tape that could be used to keep moisture out of ammunition cases.  This is why the originally Duct Tape came only in army green.
