United Caps has partnered with Brazilian petrochemical company Braskem to supply GREENER bio-sourced plastic caps and closures made from sugar cane.

Braskem Netherlands sales manager Brendan Hill said: “Braskem is pleased to be working with United Caps to bring their more environmentally sustainable GREENER closure solutions to the caps and closure market.”

The GREENER bioplastic caps are based on Braskem’s ‘I’m green’ Polyethylene, which is developed using bioethanol as the alternative to traditional fossil feedstock. Being a renewable feedstock, sugarcane captures and fixes CO2 from the atmosphere with every growth cycle, which occurs annually. As a result, the production of I’m green Polyethylene contributes to the reduction of greenhouse gas emissions when compared to traditional polyethylene, made from fossil materials.

The collaboration will add sustainable caps and closures to the existing United Caps product portfolio.

“As a result, the carbon footprint of I’m green Polyethylene is negative, when considering our life cycle analysis.”

Hill added: “As a result, the carbon footprint of I’m green Polyethylene is negative, when considering our life cycle analysis. This means that every kilogram of I’m green Polyethylene used in UNITED CAPS products results in 3.09kg of CO2 being sequestered from the atmosphere.”

Initially, United Caps will launch two bio-sourced closures, including the VICTORIA closure and PROFLATSEAL.

The VICTORIA closure is a 30/25 screw closure designed for still drinks,  while PROFLATSEAL is designed for dairy products and still drinks, both pressurised and non-pressurised.

United Caps chief marketing and innovation officer Astrid Hoffmann-Leist said: “Using bio-sourced plastics and developing high performance lighter weight caps and closures are just two of the ways we are pursuing more sustainable operations.”

The Luxembourg-based company, which has a turnover of €137m, manufactures caps and closures for the food and drink industry.

It has manufacturing facilities in Belgium, France, Germany, Hungary, Ireland, Luxembourg and Spain.
