Why is duct tape called "duck tape?"

Duck Tape is the original brand of duct tape. Original Duck Tape duct tape is still available in several strengths. Duck Tape the brand has taken on a different life through its colored and patterned tapes that people use for creative projects from binding books to making prom dresses.

Duck Tape also produces special project tapes for a variety of applications, including outdoor use tape, waterproof tape, double-sided tape, HVAC tape and box tape. In addition, the company makes tapes in clear, extra-wide, no-residue and removable formats. Not all duct tapes have the variety of the Duck Tape brand, although Tape Brothers brand is competitive.
