Sellotape was originally manufactured in 1937 by Colin Kinninmonth and George Grey, in Acton, west London.

[2] Sellotape was made at a factory in Borehamwood, Hertfordshire, from 1930 to about 1950 when it moved to Welwyn Garden City or thereabouts.

From the 1960s to 1980s, the Sellotape company was part of Dickinson Robinson Group, a British packaging and paper conglomerate.

Sellotape Industrial was bought by Scapa Group plc in 1997, and their products continue to be manufactured at its factory in Dunstable.

As an example of a genericized trademark, it gained an entry in the Oxford English Dictionary in 1980.
