Primarily Kraft Paper, Sack Paper, Formable Paper (FibreForm®) and Pulp are produced in Karlsborg. In addition there are two application laboratories with expertise in pulp optimization and development of sack- and bag solutions.
Karlsborg's production unit, just outside Kalix in Norrbotten County, is a world-leading manufacturer of Sack Paper, Formable Paper (FibreForm®) and Kraft paper intended for users with very high demands on efficient, creative and functional packaging solutions. In Karlsborg, bleached pulp is also produced for delivery in bundled form. The sack paper is used for industrial packaging such as cement bags or consumer products as animal food. The kraft paper is used as packaging paper for our own products and dry foods such as flour and sugar.
In Karlsborg there is also two application laboratories that offer value-creating services focusing on challenging the conventional. Product Development Center (PDC)offers analysis and development of sack constructions with a focus on powdery products like building materials, chemicals, minerals, flour and sugar. PDC also offers the development of materials and solutions for bag packaging. Especially for dry foods such as flour, sugar and grains but also service in handbags for fashion or food. PulpLab collaborates with several of BillerudKorsnas own factories to develop the company's own pulp products. In addition to developing our own pulp product, the lab also offers evaluation, development and processing of customers' pulp.

Sustainability & Documents
Karlsborg started production of pulp in 1914. Four years later parts of the factory was closed down and large parts of the machinery were sold. 1929 the production was resumed and in 1937 the state-owned Domänverket became the owner of the plant. In 1942 ASSI AB (Aktiebolaget Statens Skogsindustrier) took over operations and invested in a new pulp mill that was put into operation in 1980. In 1993 Domän AB (formerly Domänverket) merged with ASSI AB and formed Assi Domän AB which operated the production plant until 2001 when Billerud AB took over as owner. 2012 Billerud AB and Korsnäs AB merged and formed BillerudKorsnäs AB.
BillerudKorsnäs challenges conventional packaging for a sustainable future. Are you interested in working with us? Welcome to visit our career pages.
