Also referred to as Tray Lidding Machines, Tray Sealing Machines, or Top Sealers; Top Seal Packaging Machines utilize heat and other methods to apply plastic film lids to trays of varying depths, sizes, and substrates. These seals produce a hermetic seal that protects food and allows for the use of modified atmosphere packaging. A tray sealing system is optimal for Produce and Food Processing packaging applications. Tray sealing is also a cost-effective and environmentally-friendly packaging solution using up to 25% less packaging material than other packaging methods.


Filled trays are moved through the machine via motorized conveyors. Tray groups are then picked up by the tray sealing machines mechanical arms and the lids are applied. The arms then deposit the sealed trays on the exit conveyor.

The airtight hermetic seal provided by heat seal machines allows for modified atmosphere and vacuum packaging. MAP is a process where oxygen levels inside of a sealed package is dropped to 0%. This slows down the development of harmful aerobic bacteria that cause spoilage.

Heat sealing helps improve food safety by providing a strong airtight seal that prevents contamination. The air tight seal prevents dirt and moisture from entering the container. Specialty films are also available to reduce contamination from sources like harmful UV rays and harmful gases. Tray Sealing also provides excellent protection from tampering with tamper evident lids. These lids will leave distinctive signs when a package has been opened alerting everyone to the risk of tampering.
