Unilever has worked with Mondi to develop a new high-barrier paper-based packaging material for Unilever's Colman's Dry Meal Maker and Sauces range. The plastic content was reduced and the paper content increased, ensuring recyclability in the existing UK paper waste stream.
By replacing the previous, non-recyclable multi-material composite with recyclable paper packaging, Mondi is supporting Unilever in its sustainability goals. Both the aluminium and all unnecessary plastic layers of the previous material have been eliminated.
The solution was a new packaging with a paper content of 85 % and an ultra-thin functional plastic layer that seals the packaging and provides a protective barrier for the food. The Mondi and Unilever R&D teams identified this layer as the minimum acceptable level of protection required to ensure a long shelf life while maintaining high quality and reducing food waste.
