Top Seal Machines

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.

How Tray Sealing Machines Work

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.

Benefits of Tray Sealing

Extended Shelf Life

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.

 

Improved Food Safety

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.

Fast Tooling Changeovers

Crawford Packaging’s line of heat sealers are capable of changeovers as fast as 2 minutes. These fast changeovers minimize machine downtime by using interchangeable parts trays and a programmable interface for changing pack parameters.

 
 
 

Customizable Tray Sealing Film

Top sealing films are available in a variety of compositions that allow for different uses. Many of these compositions can feature colored printing for displaying brand and informative messaging. Options are also available for peelable films, re-sealable films and cold and hot sealing methods.

Increased Throughput Volumes

Our tray sealing packaging machines are fully electric and feature chain-driven conveyors. This allows the machines to operate efficiently and reliably at high speeds. Some of our top seal machines can run up to 175 packs per minute on small containers.
