Sellotape

Sellotape
Sellotape is a European brand of transparent, cellulose-based, pressure sensitive adhesive tape, and is the leading brand of clear, pressure sensitive tape in the United Kingdom. Sellotape is generally used for joining, sealing, attaching and mending. It is also referred to as cellophane 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 tape was originally manufactured in Acton, West London. From the 1960s to 1980s, the Sellotape company was part of Dickinson Robinson Group, a British packaging and paper conglomerate. In 2002, it was bought by Henkel Consumer Adhesives, which continues to manufacture the tape in its factory in Dunstable, Bedfordshire.
Sellotape Original is made using cellulose film derived from wood pulp. The cellulose film decomposes naturally in soil, and is naturally easy tear and non-static.
The Sellotape brand now covers a variety of tape products, and the word is frequently used to refer to other adhesive tapes in many countries due to its market exposure. As an example of a genericised trademark, it has an entry in the Oxford English Dictionary

Scotch Tape is a brand name used to describe 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.[1] Although it is a trademarked brand name, it is sometimes used in the US and elsewhere as a generic term for transparent adhesive tape. The Scotch brand includes many different constructions of tape.
Use of the term "Scotch" in the name has a pejorative origin. To cut costs 3M applied the adhesive only to the edges of the tape. A remark was made by a St. Paul automobile detailer that the stingy Scotch bosses needed to put more adhesive on it.[2] Scotty McTape, a kilt-wearing cartoon boy, was the brand's mascot for two decades, first appearing in 1944.[3] The familiar plaid design, a take on the Wallace tartan, was introduced in 1945.[3]
The Scotch brand and Scotch Tape are registered trademarks of 3M. Besides using "Scotch" as a prefix in its brand names (Scotchgard and Scotchlite), the company also used the name "Scotch" for its (mainly professional) audiovisual magnetic tape products,[4] until the early 1990s when the tapes were branded solely with the 3M logo. In 1996 3M exited the magnetic tape business, selling its assets to Quantegy (which is a spin-off of Ampex).
The material has uses in research as well. The Scotch Tape Test is conducted in conjunction with an Instron device to gauge the adhesion strength of conducting polymers adhered to indium tin oxide glass slides. The study was made famous by a group at the Thayer School of Engineering at Dartmouth College
