United Caps has expanded its bio portfolio in a collaboration with Brazilian petrochemical company, Braskem. Together the two companies have created and launched new sustainable caps and closures derived from sugar cane. The new caps, made from the fossil fuel alternative, will use a bioplastic resin to form the caps and closures. “Using bio-sourced plastics and developing high-performance lightweight caps and closures are just two of the ways we are pursuing more sustainable operations,” said Astrid Hoffmann-Leist, chief marketing and innovation officer, United Caps. United Caps will initially launch two standard forms of the sustainable caps – a 30/25 screw closure for still drinks and Proflatseal, for dairy products that are both pressurised and non-pressurised.
