Duni Group Introduces Sealable Paper Bowl to Extend Freshness and Reduce Food Waste
Duni Group has launched Sealable Ronda, a new sealable paper bowl under its Duniform brand, designed for salads, bowl meals, sushi, and other ready-to-eat food products. The innovative packaging combines paper-based materials with hermetic sealing and Modified Atmosphere Packaging (MAP) technology to help keep food fresh for longer while reducing food waste.
The launch comes as demand for ready-made meals continues to grow, creating a need for packaging solutions that offer extended shelf life, food safety, and lower environmental impact. Sealable Ronda addresses these requirements by enabling secure sealing in a paper-based format, helping food producers and retailers maintain product quality throughout distribution and retail operations.
Compared to similar plastic-based bowls, the new packaging contains over 85% less plastic and delivers more than 50% lower CO₂ emissions, supporting sustainability goals across the food packaging sector.
The sealed design provides a leak-resistant, tamper-evident, and hygienic packaging solution that protects products during transportation and storage. It also offers consumers clear visual assurance that the package remains unopened.
According to Marie Davies, Category Manager for Trays and Films at Duni Group, reducing food waste is one of the most effective ways to lower the environmental impact of food. She noted that Sealable Ronda helps customers maintain freshness for longer while delivering a secure paper-based packaging alternative.
Designed for modern food concepts, the round bowl offers strong shelf appeal, easy stacking, and compatibility with both hot and cold food applications. It is manufactured using FSC®-certified and other controlled materials and can be customized with printed branding and product information.
Sealable Ronda is offered as part of Duniform’s integrated packaging system, which includes compatible films, sealing equipment, and support services. The solution aims to improve production efficiency, optimize logistics, and support a more sustainable food packaging value chain by reducing both food waste and resource consumption.
The launch reinforces Duni Group’s commitment to developing packaging innovations that enhance food safety, extend shelf life, and contribute to more sustainable food experiences.
