Working toward a goal of putting the FSC label on all of its packages, Tetra Pak has already made the packages available in several countries, beginning with the introduction of the world's first FSC-labeled liquid food cartons in the U.K. in 2007. The FSC label indicates that the wood fibers in the package can be traced through the supply chain and that the paperboard used in the package comes from FSC-certified forests and other controlled sources.
