Returning to Sweden in 1920, Rausing continued his employment at SLT, first as a Manager Assistant and then as a Manager. During his time at SLT, Rausing became closely acquainted with the industrialist Erik Åkerlund and in 1929 Rausing left SLT to form a new packaging company together with Åkerlund in Malmö, Åkerlund & Rausing. Åkerlund & Rausing was the first packaging company in Scandinavia and eventually became a leading manufacturer of dry food carton packages. Initially, however, the company had difficulties making profits and in 1933 Åkerlund sold his share to Rausing, who became the sole owner.
