The Kareline natural fibre composite is produced at the factory of Plasthill in Kontiolahti, northern Finland. It has been in production since 1996.
Kareline is produced from coniferous pulp and plastics suitable for foodstuffs, both with share of 50 percent. The material can be formed freely using a so called injection molding technique.
The products resemble wood closely. It can be dyed to almost any color. The material can also be welded. There is no need to use glue in the production. After use the product can be safely disposed by, for example, burning.
The use of wood fibre decreases material’s environmental load. Material is used to make grips for handguns, musical instruments and foodstuffs dishes. A Finnish Uitto Boards company also manufactures skateboards from Kareline.
