Food packaging is expected to do more than ever before. It must protect products, support operational efficiency, improve consumer convenience, and contribute to sustainability goals. With the combination of CUBO and the Click In sealing lid, Greiner Packaging has developed an integrated solution that addresses these requirements across the entire value chain.
At the heart of the concept is CUBO, a square cup format that challenges the industry's traditional reliance on round packaging. By rethinking geometry, CUBO improves space utilization throughout transport, storage, and retail display while maintaining the robustness required for demanding food packaging applications. The square design also creates flat surfaces for branding and product communication, helping products attract attention at the point of sale.
The Click In sealing lid complements this approach with a simplified closure system. Instead of using a traditional combination of sealing foil and snap-on lid, the solution consists of just two components: container and lid. The lid features an intuitive mechanism that provides a tactile and audible "click" when securely closed, giving users confidence that the package is properly sealed while allowing repeated opening and re-closing.
The square geometry of CUBO enables up to 30% more cups per pallet compared to a conventional round cup of the same size and volume1, while the Click In sealing lid simplifies the packaging structure by replacing the traditional combination of sealing foil and lid. Together, they demonstrate how coordinated packaging innovations can help optimize resource use, streamline operations, and support sustainability goals without compromising functionality. Thanks to CUBO's lower height and optimized stackability, the square cup can eliminate up to 160 truck journeys2, reducing transport costs while lowering the CO2 footprint.
This holistic perspective demonstrates how coordinated packaging innovations can create value across production, distribution, retail, and consumption.
