Here is a youtube video where an employee of 3M in Canada takes us on a tour of the 3M plant there and shows us how duct tape is make. Remember, its not Duck Tape, unless your a quack!The biggest duct tape factory is in London, Ontario.
First, learn about all the ingredients you need to make duct tape. Rubber from the far east and resin from Texas, and Calcium Carbonate from Ontario and a few other tid bits.
The machine that makes the duct tape is pretty big and probably a bit beyond what you can do in your basement or living room... so I suspect your better off going to the office supply store to get your duct tape.. and not trying to make it at home!
Remember, never use duct tape (or Duck tape) for any criminal activites).
