About us

The brothers Gunnar and Ivar Kjellin founded Katoplast in 1972. The “Katoplast” name originated from the letters (Ka)ri and (To)ve in the names of the spouses of the company promoters. The business started in Gunnar Kjellins garage, with the owners as the only employees.

The activity moved several times to larger locations. In 1983 it was decided to build our own factory premises in Tistedal, a small town in municipal Halden.
The new premises opened in the autumn of 1984. There has been need for some enlargement since this.

The company is today owned and runned by Laila and Trond Vidar Kjellin. Trond Vidar has been Managing Director since 2011.
During these years there has been done huge investments in the production equipment and contains today of energy smart machines with free programmable robots.
