The story
The Tetra Laval Group was created in 1993 after Tetra Pak's acquisition of Alfa Laval in 1991 with the aim of forming a coherent structure under which both companies could operate within their respective fields. The part of Alfa Laval that was involved in processing was integrated into Tetra Pak, while the part that produced farm equipment was recreated as a separate entity under the name of Alfa Laval Agri, later renamed DeLaval after Alfa Laval's founder Gustaf de Laval.
In 2000, Tetra Laval sold the part of Alfa Laval that was not directly involved in their business to Swedish investment company Industri Kapital, however retaining a part of the shares. In 2001, Tetra Laval acquired French plastic bottle manufacturer Sidel. The merger was subject to anti-competitivity scrutiny from the European Commission but was finally allowed to go through after an appeal to the European Court of Justice.
