United Caps has collaborated with Brazilian petrochemical company Braskem to introduce two new bio-sourced plastic bottle caps and closures made from sugar cane.
The Victoria closure is a 30/25 screw closure designed for still drinks, and the Proflatseal cap can be used for dairy products and still drinks, both pressurised and non-pressurised.
Both caps and closures are manufactured using the I’m green Polyethylene bio-plastic resin developed by Braskem, which is derived from sugar cane, creating a “renewable alternative to traditional fossil fuels.”
According to Braskem, sugarcane captures CO2 from the atmosphere with every annual growth cycle, meaning the material contributes to the reduction of greenhouse gases when compared to conventional polyethylene caps and closures.
Astrid Hoffmann-Leist, chief marketing and innovation officer for United Caps said: “As we continue to take steps to ensure our caps and closures are as sustainable as possible, this partnership with Braskem is an important step in that direction.
“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.”
Brendan Hill, sales manager at Braskem Netherlands B.V added: “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 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 3.09 kilograms of CO2 being sequestered from the atmosphere.
“Apart from the feedstock, I’m green Polyethylene follows the same production process as traditional fossil Polyethylene, ensuring that our Polyethylene has the same characteristics, quality and properties as the fossil equivalent.
“It goes without saying that I’m green Polyethylene fits all existing end-of-life scenarios and that our ethanol is sustainably sourced with clear chain of custody certification possible.”
