Permacel, part of the Johnson & Johnson company, invented duct tape for use during World War II. This duct tape was useful for fixing exterior truck damage, sealing containers and making other repairs during the war. After the war, it became popular among civilians as well.
Duct tape was created using medical tape with polycoat adhesive to give the tape more advanced sticking properties. The tape was then coated with polyethylene and attached to cloth for both flexibility and strength. Duct tape was army green during the war, but when it was mass-produced commercially, it was released in gray. The brand name Duck Tape was created by Manco, Inc. and became very popular for making duct tape in various colors.
