The paper mill was started in 1931 by a group led by the internationally well-known businessman, Christian Storjohan.
As early as 1964 a computer system was installed to control PM4, which is regarded as a pioneering moment in the process industry. In 1972 Gruvön was among the first mills to use oxygen for bleaching, which cut the use of chlorine by half. The mill stopped using chlorine fully in production in 1991.
Gruvön is also well known for its innovation. The mill was the first in the world to produce White Top Liner and is still the first to introduce white liner for applications where appearance and good printing results are important. Gruvön produces sack and kraft paper, fluting and white liner for containerboard, and market pulp.
