Stainless hollows used for food packaging

Tetra Pak, a liquid food packaging machinery manufacturer, has selected Stalatube Oy’s stainless steel hollow sections for the frame structures of its packaging machines. Economical feasibility and flexibility of installation are cited as major attributes of the Stalatube sections. Stainless steel hollow sections cut to length directly on the production line allow a wide variety of structural solutions. This method, developed by the Finnish company Stalatube Oy, particularly suits the structures of liquid food packaging machinery. “We switched to using stainless steel tubing more than ten years ago. Hygiene aspects alone set it apart from black steel,” says Lars Johannesson, who is responsible for production at Tetra Pak’s plant in Lund, Sweden.
Tetra Pak subcontract their frame manufacture. “We assemble the machines from five different modules which we obtain in ready-made form,” Johannesson explains.
Thanks to Stalatube’s cut-to-length service for stainless steel sections, Tetra Pak can avoid cutting waste. The method also allows cutting to required angles. By means of precision cutting, tolerances of ±1 mm can be obtained. The frame assembly can begin as soon as the steel section delivery arrives at the customer.
