Scotch Tape is a brand name used for certain pressure-sensitive tapes manufactured by 3M as part of the company’s Scotch brand.
The precursor to the current tapes was developed in the 1930s in Minneapolis, Minnesota by Richard Drew to seal a then-new transparent material known as cellophane.
Although it is a trademarked brand name, Scotch tape is commonly used in the United States, Canada, Italy, Russia, Ukraine and elsewhere as a generic term for transparent adhesive tape. (The Irish, New Zealand, South Africa and UK equivalent of Scotch tape is Sellotape. The Australian term is sticky tape) The Scotch brand includes many different constructions (backings, adhesives, etc.) and colors of tape.
The use of the term Scotch in the name was a pejorative meaning “stingy” in the 1920s and 1930s. The brandname Scotch came about around 1925 while Richard Drew was testing his first masking tape to determine how much adhesive he needed to add. The bodyshop painter became frustrated with the sample masking tape and exclaimed, “Take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it!” The name was soon applied to the entire line of 3M tapes.
