Duni Group has launched a sealable paper bowl for ready meals, utilizing hermetic sealing and modified atmosphere packaging to extend product freshness and reduce food waste.
The Sealable Ronda was developed to meet the increasing demand for ready meal packaging that supports food waste reduction while maintaining performance. It is suitable for salads, sushi, poke bowls, and hot meals.
Marie Davies, category manager for Trays and Films at Duni Group, says: “Reducing food waste is one of the most effective ways to lower the climate impact of food. With Sealable Ronda, we enable our customers to keep ready‑to‑eat meals fresh for longer, while offering a secure, sealed solution in paper. This strengthens food safety and confidence throughout the value chain.”
The solution taps into consumer and industry demand for plastic reduction, featuring more than 85% lower plastic content and more than 50% lower CO2 emissions. This is according to Duni Group’s internal Product Carbon Footprint Calculator within its Food Packaging Solutions division.
Product protection
The hermetic sealing enables the solution to be leak-resistant, tamper-evident, and hygienic, offering product protection during transport.
In addition, Duni Group claims that the Sealable Ronda responds to “clear market demand” for secure, sealable paper bowls, “combining a high share of renewable material with functionality that has long been standard in plastic packaging.”
The circular-shaped paper bowl is easy to stack and handle in-store, says Duni Group. It is made from FSC-certified paper and is suitable for personalized brand printing.
The solution was also developed to improve logistics and reduce downtime in production. It is part of Duni Group’s Duniform range, a packaging concept designed for the food industry, professional kitchens, restaurants, hotels, and grocery retail.
Earlier this year, Duni Group launched the ReMuc “Ois im Kreis” (everything in the circle) project, a reusable food container system, in Munich, Germany, in which five automated return stations were placed in the popular food market, Viktualienmarkt.
