L-550 automatic tray sealer

The L-550 is an automatic tray sealer for plants that need a high pace without giving up a wide variety of packs. According to its catalogue sheet it reaches up to 12-15 cycles per minute, works in modified atmosphere by combining vacuum and gas, and offers a sealing area of up to 400 × 280 mm. With those three figures a first production estimate can be made from the very first contact.

The sealing area is what gives it its versatility. A 400 × 280 mm area takes large trays of ready meals or meat, but also multi-cavity moulds for tubs, cups or small trays of sliced meats and cheese. The more units fit per cycle, the more output multiplies: with a multi-cavity mould, 12-15 cycles per minute turn into many more sealed units.

Vacuum followed by gas flushing removes the air from the pack more thoroughly before the protective gas mixture is introduced. It is the usual technique for meat, cured meats, fish and ready meals, where residual oxygen shortens shelf life. If your product does not need modified atmosphere, mention it when you ask for a quote and we will assess the most suitable configuration.

When should you choose the L-550 over its sister models? The semi-automatic MAP tray sealer stays at 3-4 cycles per minute with manual loading: it suits short runs. The LS-975 and LS-1375 are in-line models to integrate with conveyors in plants with sustained volume. The L-550 fills the middle ground: automatic, with a known output and with a generous sealing area for working with very different packs.
