Unilever and Mondi have partnered to develop a new high barrier, paper-based packaging material for Unilever's Colman's dry Meal Maker and Sauces range. Their goal is to reduce plastic, increase paper content, and consequently ensure recyclability in the existing UK paper waste stream. By replacing the previous unrecyclable multi-material laminate with recyclable paper packaging, Mondi is supporting Unilever in its sustainability targets. The aluminum, as well as all unnecessary plastic layers of the previous material, were eliminated. This resulted in a new packaging solution with paper content of 85% and an ultra-thin functional plastic layer that seals the packaging and provides barrier protection for the food. Mondi and Unilever's R&D teams identified this layer as the minimum acceptable protection needed to ensure a long shelf life while maintaining high quality and reducing food waste.
