Are Duck Tape and Duct Tape the same thing?
Duck Tape is a brand name for one make of duct tape. Duct tape was originally meant to seal the seams on heating ducts. It comes in two kinds, one with a coarse fabric backing and a semi-shiny surface that is most usually silver, and the other is a tape of very thin metal which is a very shiny silver colour. The first one is the one that also comes in many colours and the one that people now use for all kinds of different purposes. Gaffer’s tape is also fabric backed but the fabric is much finer than that used in duct tape and the surface of the tape is not shiny at all. It’s used a lot in film production, hence the name.
