Rosti
Our History
Rosti has a History of Precision Plastic Injection Molding Solutions dating back to 1944
Founded in Denmark by Rolf Fahrenholtz and Stig Jørgensen, Rosti began with the production of buttons through injection molding, shortly after the Second World War. This innovative and relatively new method provided higher production at a lower cost compared to conventional press molding.

Founded in Denmark by Rolf Fahrenholtz and Stig Jørgensen, Rosti began with the production of buttons through injection molding, shortly after the Second World War. This innovative and relatively new method provided higher production at a lower cost compared to conventional press molding.
In 1948, the company started to produce mixing bowls and dinnerware made of melamine. The Margrethe mixing bowl, named after Queen Margrethe of Denmark and designed by renowned Danish industrial designer Jacob Jensen at Sigvard Bernadotte and Acton Björn’s design studio for Rosti, remains a kitchen icon more than 60 years after its first production. By the mid-fifties, Rosti was producing melamine cosmetic packaging for beauty industry leaders Elizabeth Arden and Helena Rubinstein.
Major Changes in the 1960s
In 1965, Rosti became a limited company. The company also started producing plastics for petroleum companies as petroleum became a widely used fuel at that time.
Rosti received its largest order for 2,000 10-liter jugs for the oil giant BP. The production of jugs for a number of other oil producers, including Shell, Esso, and 4K, followed and Rosti became one of the largest producers of plastic petroleum jugs, in addition to its existing melamine product line.
Part of A.P Moller – Maersk Group
In 1971, Rosti became part of the A.P. Moller – Maersk Group, a world leader in shipping, oil, and logistics.
Supported by the strong reputation and financial stability of its new owner, Rosti started acquiring several companies in various countries around the world—including the USA and Mexico—that same year, forming the Rosti Group.
In 1989, Rosti became two divisions: Rosti Industrial and Rosti Houseware. In 1993, the houseware division was sold to the Dutch company Mepal BV and merged to form a single enterprise that is today known as Rosti-Mepal.
Acquired by Nordstjernan
In 2010, Rosti’s industrial division, with activities across Europe and Asia, was acquired by the family-controlled Nordic investment company Nordstjernan and became a wholly owned part of the Nordstjernan Group.
This ownership has provided us with the advantages of resources, financial security, and the strong reputation of both past and present partners.
Expanding in Europe and Asia
In 2026, Rosti acquired Alvi Group, adding sites in Norway, Sweden, Poland, and China and around 400 colleagues. Norway became a new country in Rosti’s portfolio, and Rosti Sweden, Rosti Poland, and Rosti China each gained a second site. The acquired sites now operate as Rosti Norway, Rosti Sweden, Rosti Poland, and Rosti China.
