Read moreOrganizations in the food and beverage industry understand how vital packaging can be in keeping food fresh, ensuring it is easily transportable, and attracting customers. However, with so many different food packaging solutions available on the market, it can be easy to get lost in the jargon and variety of options.
Don’t stress. Your friends at Crawford Packaging are here to make it simple for you with this complete guide to tray sealing.
Also referred to as tray lidding machines, heat sealers, or top sealers; tray sealers are machines that apply plastic film lids to trays of varying materials, sizes, and depths. It is because of this versatility that top seal is the optimal packaging solution for a variety of applications, including industrial fasteners, fresh produce, meat, frozen meals, and ready-made meals.
Product-filled trays enter the in-feed conveyor where they get indexed and spaced. These are then picked up by a transfer beam to be transferred within the tooling. The seal plate then picks up the product-filled trays and lifts them against the film. The film and trays are then compressed against the heated upper tooling to activate the sealing properties against the tray, while simultaneously cutting the film. Finally, after seal dwell time has elapsed, the seal station lowers the trays back down and the transfer on the next cycle ejects to the out-feed of the machine.
There are two main types of tray seal machines:
Fully automatic tray sealers are most suitable for medium and large-scale operations. What makes them fully automatic are the conveyors that push the trays through the machine, lessoning the need for manual intervention.
Packaging Automation also offers several automatic machines, namely the Revolution. This tray sealing machine can seal up to 200 packs per minute, making it the fastest tray sealer on the market today.
Peelable – Film that can be removed once with minimal effort
Resealable – Film that can be opened and resealed by the consumer multiple times
MAP (Modified Atmosphere Packaging) – Film that has micro-perforations to control oxygen flow in and out of the package. This helps to extend the shelf life of perishable items.
