Promens' roots can be traced to 1984 when local investors in Dalvik in Northern Iceland founded Sæplast to produce double-walled, insulated plastic tubs for storing fish. Driven by demands from the Icelandic fisheries industry to develop a product that extended the quality lifetime of fish, Sæplast developed its revolutionary double-walled insulated plastic tub.
In 2004, the Icelandic investment company Atorka Group gained majority share and took Sæplast off the Iceland Stock Exchange. The following year Atorka formed the Promens Group, which became the parent company of Sæplast, which name was later changed to Promens Dalvik. Promens then acquired Bonar Plastics in 2005 and Elkhart Plastics, Inc. and Polimoon in 2006
