Harpak-Ulma has launched a purpose-built application of the Mondini Trave Sinfonia platform for high-volume ground-meat production, delivering fully automated, high-throughput tray sealing that redefines performance expectations.
Sinfonia can double throughput compared to typical mechanical grind-line tray sealers, increasing output from roughly 120 packs per minute to as high as 200 packs per minute. Sinfonia’s software-controlled magnetic-transport architecture delivers this by moving trays on independent shuttles with micron-level accuracy. The innovative design eliminates belts, pusher arms, and other friction-based components that typically constrain sealing speed, especially in low-oxygen MAP applications.
“The competitive ceiling for grind-line tray sealing is around 120 ppm. With Sinfonia, we can engineer a 200-ppm grind line – almost a 100% throughput increase,” said Carlo Bergonzi, product manager, Tray Sealing at Harpak-Ulma. “Sinfonia fundamentally changes what’s possible in ground-meat tray-sealed packaging,” he added. “By controlling each tray independently, we remove the mechanical constraints that typically dictate line speed. The result is a faster, cleaner, and far more stable tray-sealing process that simply isn’t achievable with conventional systems. Given the momentum behind meat-brick formats across major retailers, this application directly addresses the performance conversations we’re hearing from processors as they head into IPPE 2026.”
The configuration integrates portioning, dual denesting, retractable conveyor loading, and a 14-up sealing array, allowing each station to operate independently at optimal speed. Sinfonia delivers a consistent, contamination-resistant tray path, easier changeovers, and a compact footprint – performance levels that mechanically indexed, traditional systems cannot match.
