The Tetra Rex Bio-based package is manufactured solely from paperboard and plastics derived from plants. All the paperboard used comes from FSC-certified and controlled sources, and is traceable to its origins. The low-density polyethylene used to create the laminate film for the packaging material and the neck of the opening is produced for us by the Brazilian chemical company, Braskem. It is derived from sugarcane, as is the high-density polyethylene used for the cap.
The caps are identical in appearance and functionality to those produced using fossil fuels, and the carton itself is indistinguishable in weight and feel from the standard Tetra Rex carton. The only way it can be identified is because the words “Bio-based” are printed on the gable. The package has been awarded the highest category of bio-based certification from internationally recognized assessment body Vincotte.
