At Interpack 2026, Multivac presents a tray sealer line that enables the simultaneous packaging of different products. The goal is to make production processes more flexible and increase the utilization of existing capacity. The line on display is based on an integrated concept combining product feeding, packaging, labeling, and sorting.
Tray sealer line processes multiple product streams in parallel
At the heart of the application is a tray sealer line operated with two independent feed streams. Identical trays are filled in parallel with different products, such as chicken drumsticks or chicken wings. This configuration makes it possible to process different products simultaneously and utilize production capacities efficiently.
AI supports identification and labeling
After the packaging process, an AI-supported system identifies the products. Based on this data, the appropriate label is automatically generated and applied. The “L 310” labeling and inspection system handles both product recognition and labeling, thereby contributing to process automation.
Efficient utilization through integrated line solution
The combination of product identification and automatic labeling enables optimized use of tray sealer capacities. The packages are then sorted by type and stacked, with two pack stackers organizing the material flow within the line.
Tray sealer line reduces material consumption
Another focus is on reducing material usage. The “TX 720” tray sealer used is equipped with a close-cut tool that reduces film consumption and improves format utilization. “The tray sealer exhibited at Interpack is equipped with a new close-cut tool that contributes to the sustainability of the solution through optimized material consumption,” explains Franziska Schreiber, Product Manager for Tray Sealers at Multivac. “The tool seals the trays directly next to one another, tray by tray. This eliminates the need for film cutting between the trays. As a result, up to 30 percent of film waste and corresponding costs can be saved. In addition, format utilization is optimized, and in the best-case scenario, there is room for an additional tray in the machine.”
Scalable concept for various applications
The configuration shown is an example implementation and can be expanded to accommodate additional feeding and packaging streams. This allows the concept to be adapted to different production requirements and integrated into existing lines. You can find Multivac at Interpack 2026 in Düsseldorf in Hall 5 at Booth A23.
