'Scotch tape' is the trade name for the clear cellophane adhesive tape widely used in stationery and packaging. It was invented in 1925 by Richard Drew, who worked as an engineer at the 3M sandpaper mill (Minnesota Mining and Manufacturing) in the USA, and seeing the difficulties of his customers to neatly paint the white lines on the body of automobiles, he came up with the idea of putting adhesive on strips of paper creating the "masking tapes". As early as 1930 he made the cellulose paper version, which was more popular for sealing bags and repairing tears in paper and cardboard. The name has a somewhat racist origin; It turns out that the first versions for painting masking did not have continuous glue but in sections, or only near the edges of the tape, and not in the middle; That made it peel off easily and the paint to sneak inside, prompting one customer to complain "Tell your boss's Scotsman to put glue all over the tape!", because at that time Scotch people were said to be very stingy, and the word was used synonymously. That's where the inspiration for the brand and the plaid design packaging came from. See tape tape.
