DuPont Teijin Films have consistently driven innovation in the polyester industry from the initial invention and development of the polymer in the 1940s through to their current position as the world’s largest supplier of heat sealable BOPET films driving the move to recyclable mono PET tray and lid structures. With the launch of the new LuxCR™ process, DuPont Teijin Films are addressing some of the limitiations of mechanically recycled PET by depolymerising the material back into the monomer unit bis(2-hydroxyethylterephthalate) or BHET before converting into a wide range of BOPET films covering applications as diverse as food packaging, labels, solar panel back sheets, ID cards and more.

The upcycling of mechanically recovered PET marks an important step forward in the drive towards a more sustainable future for the packaging industry where depolymerisation is used to restore the material properties to ensure plastic to plastic recycling, providing a balance between the amount of waste material generated and the amount of high value end use applications that it can be recycled into.
