United Caps and Braskem embrace bio-sourced plastics for greener closures

Made from sugar cane, bio-sourced plastics offer a new level of sustainability

United Caps, an international manufacturer of caps and closures, and Braskem, a leading Brazilian petrochemical company, reported they have collaborated to deliver to the market greener bio-sourced plastic caps and closures made from sugar cane as an addition to the United Caps product portfolio.

Bio ethanol, the feedstock for I’m green^™ Polyethylene, the basis for United Caps greener bioplastic caps, is derived from sugarcane, a renewable alternative to traditional fossil feedstocks. Being a renewable feedstock, sugarcane captures and fixes CO₂ from the atmosphere with every growth cycle, which occurs annually. This means that the production of I’m green^™ Polyethylene contributes to the reduction of greenhouse gas emissions when compared to conventional polyethylene, made from fossil materials.

“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 3.09 kilograms of CO₂ being sequestered from the atmosphere,” Brendan Hill, Sales Manager at Braskem Netherlands B.V., explained “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,” he added “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.”

United Caps is initially bringing to market two standard closures manufactured using bioplastic resin from Braskem, including:

• The VICTORIA closure, a 30/25 screw closure designed for still drinks.
• PROFLATSEAL, ideal for dairy products and still drinks, both pressurized and non-pressurized.

Its custom-designed caps and closures solutions have been one of the most sought-after solutions in the packaging industry for years.
