Mondi, a global leader in packaging and paper, has partnered with chemical company Evonik to introduce a recyclable pre-made paper bag designed for chemical powders. This innovative packaging solution aims to reduce the carbon footprint associated with transporting fumed silica, a performance additive used in various industrial and consumer applications.
The collaboration began in 2022 when Evonik sought more sustainable packaging alternatives. Working closely with Mondi, the team developed a two-ply pre-made paper-based bag that eliminates the need for a plastic-coated paper layer previously used. This change has led to a 30% reduction in the overall weight of the packaging, resulting in less material usage and a lower carbon footprint. Mondi's in-house Product Impact Assessment (PIA) tool was employed to evaluate the environmental benefits of the new packaging.
The new paper bags are constructed using Mondi's high-porosity kraft paper, which provides superior strength, durability, and stretch. A minimal spot coating is applied to enable secure sealing after filling. The bags are recyclable according to the CEPI v.3 test method and 4evergreen's fiber-based packaging recyclability evaluation protocol.
Evonik conducted extensive testing to ensure the suitability and product protection of the new bags. Following successful trials, the bags have been launched to the market and are now being used for filling, palletizing, and distribution.
Florian Ullrich, Sales Director Paper Bags Germany at Mondi, stated, "Valve bags are designed for high-speed filling, and with sensitive contents such as these specialty chemical powders, high-quality material and secure closing options are also paramount. Being able to deliver and indeed improve on these elements, while reducing the carbon footprint of the packaging, was a challenge we were delighted to answer alongside Evonik."
This collaboration exemplifies how industry partnerships can lead to innovative solutions that align with sustainability goals and contribute to reducing environmental impact.
