In an effort to enhance recyclability and reduce complexity, the project focused on transitioning from traditional laminated metallized films to a mono-material polyethylene (PE) solution. This innovative approach was a collaboration between ExxonMobil and Constantia Drukpol, aiming to create packaging that aligns with Bonduelle’s circular economy goals.
By utilizing ExxonMobil’s advanced PE resin technology, the packaging developed features excellent sealability, mechanical strength, and puncture resistance. The use of ExxonMobil’s Exceed performance polyethylene resulted in improved performance in puncture and tear resistance, particularly for challenging-to-pack vegetables such as spinach and broccoli.
This development represents a significant milestone for Bonduelle as it strives to achieve its goal of 100% recyclable or reusable packaging by 2025. The new film also resulted in a 25% reduction in packaging material for their frozen product range in France, marking a positive step towards reducing plastic usage.
Arnaud Warusfel, packaging development manager at Bonduelle Europe Long Life, explained, “For our retail Frozen Bag Category, we wanted to replace our historical multi-material metallized film since it was difficult to recycle.” The decision to opt for a mono-material PE solution without adhesives was made to enhance recyclability compared to multi-material alternatives. Despite facing challenges during the development process, the technical expertise of Constantia Drukpol and ExxonMobil enabled the project to overcome them successfully.
Overall, this collaboration has paved the way for sustainable packaging solutions in the food and drink industry, aligning with current consumer trends towards eco-friendly practices. The partnership showcases the importance of innovation and collaboration in driving positive change towards a more sustainable future.
