Actega's new heat-seal lacquers for the internal coating of aluminium coffee capsules are PVC-free and therefore contribute to improved recyclability.
Thanks to their excellent barrier properties, aluminium coffee capsules protect the coffee powder from external influences such as oxygen, light and moisture. With 27 billion aluminium capsules filled worldwide in 2022 However, the number of capsules in the waste stream continues to rise. This is increasing the pressure on brand owners to find new ways to make their packaging more sustainable and environmentally friendly.
