Consumers across Sweden can now buy Arla Food’s Eko brand organic milk in Tetra Rex® Bio-based from Tetra Pak (, the world’s first carton package made entirely from renewable materials. The one-litre carton, with TwistCap™ OSO 34 opening, uses plastics derived from sugar cane, plus paperboard; nothing more. Marked with “Bio-based”, it is the only fully renewable package that offers complete material traceability – so consumers know that every part of the package they hold in their hands is derived only from plants.
