Duni Group, through its Duniform brand, has announced the launch of Sealable Ronda, a sealable paper bowl designed specifically for salads and bowl-based meals. The innovation marks a significant shift in the ready-meal segment by combining paper-based materials with hermetic sealing and Modified Atmosphere Packaging (MAP) technology to address the dual challenges of food waste and plastic reduction.
The solution is engineered to provide the functional benefits typically associated with plastic packaging, such as extended freshness and secure transport, while utilising high-performance renewable materials.
Extended Freshness via Modified Atmosphere Packaging
Food waste remains a primary sustainability hurdle in the ready-to-eat category. Sealable Ronda addresses this by enabling hermetic sealing and the use of Modified Atmosphere Packaging (MAP), which displaces oxygen within the container to slow down spoilage.
This technical capability allows retailers and food producers to add several days of shelf life to perishable products. By maintaining product integrity for longer periods, the solution reduces the volume of food discarded due to expiration, supporting more efficient inventory management across the distribution chain.
Sustainability Metrics and Plastic Reduction
The transition from traditional plastic containers to the Sealable Ronda format offers measurable environmental advantages. According to data provided by Duni Group, the new paper-based solution achieves the following compared to plastic bowls of a similar size:
Plastic Reduction: Contains more than 85 per cent lower plastic content.
Carbon Impact: Results in more than 50 per cent lower CO2 emissions.
Sourcing: Manufactured from FSC®-certified and other controlled materials.
These metrics respond to increasing regulatory and consumer pressure on food producers to move away from virgin plastics without compromising the safety or longevity of the food product.
Operational Security and Distribution Efficiency
The hermetic seal provides a leak-resistant and tamper-evident barrier, which is essential for the rigours of modern food logistics. The secure closure reduces the risk of leakage during transit and ensures that the product remains hygienic from the production facility to the retail shelf.
For the consumer, the visible seal acts as a safety indicator, providing confidence that the meal has not been tampered with. The round bowl format is optimised for stacking and handling in retail environments, fitting into existing workflows for sushi, poke bowls, and salad concepts.
Integration within the Duniform System
Marie Davies, Category Manager Trays and Films at Duni Group, stated that the initiative is one of the most effective ways to lower the climate impact of food by directly reducing waste. The Sealable Ronda is offered as part of a comprehensive system that includes compatible films, sealing machines, and technical services.
This systemic approach is designed to reduce downtime in production facilities and improve overall logistics. The bowls are suitable for both hot and cold dishes and can be customised with printing, allowing producers to communicate branding and nutritional information directly on the primary packaging.
The launch reinforces Duni Group’s broader strategy to deliver sustainable food experiences by strengthening food safety and extending shelf life through resource-efficient packaging technology.
