3M introduced Scotch Tape, the first transparent pressure-sensitive tape, in 1930.
The product grew from 3M's earlier work on masking tape. Richard Drew, a 3M engineer, developed masking tape in 1925 to help automobile painters create two-tone finishes. The company later sought a clear tape that could be used for household repairs and packaging.
3M introduced transparent cellophane tape in 1930 under the Scotch brand. Its pressure-sensitive adhesive allowed the tape to stick without water, heat, or a separate glue layer. The product became popular for repairing torn paper, wrapping gifts, and sealing packages.
The name Scotch originated during the development of the earlier masking tape, when a dissatisfied customer reportedly told Drew to take the adhesive back to his Scotch bosses. “Scotch” here is a brand name, not a reference to the tape being made from wool or another Scottish material.
