Tray Sealing 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 packaging for fresh and frozen foods. Tray sealing is a cost effective and environmentally friendly packaging solution using up to 25% less packaging material.
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 Eclipse series of tray lidding machines is one of the most reliable family of top sealing machines available today. These machines feature easy to change over tool-sets with an inbuilt tool docking system and light weight quick release tooling. The Eclipse family of tray lidding machines can pack between 45 and 125 packs a minute.
The PA182 is a 2 station, rotating tray semi-automatic tray sealing station. The PA182 is simple to use and is able of sealing up to 40 packs per minute. It is a flexible, easy to use machine that features an intuitive touch screen display and is designed for rapid tool change overs.

The airtight hermetic seal provided by tray lidding 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.
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.
Tray 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.
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 tray sealing machines can run up to 175 packs per minute on small containers.
Crawford Packaging’s line of tray sealers is 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.
