Answer:
Sellotape is another name for Cellophane Tape. It is a European brand of transparent, cellulose-based, pressure sensitive adhesive tape. The name ‘Sellotape’ was coined in 1937 by Colin Kininmonth and George Gray, who made the product by applying rubber resin to Cellophane film. The name was derived from Cellophane, which was a trademarked name at that time. The "C" was changed to "S" so that the new name could be trademarked.
