Also known as tray lidding machines, tray sealing machines are that kind of machines that apply plastic film lids to trays of varying materials, sizes, and depths. It is the best packaging solution for a wide range of applications, including industrial fasteners, fresh produce, meat, frozen meals, and ready-made meals, due to its versatility.
Product-filled trays enter the in-feed conveyor where they get indexed and spaced. A transfer beam then picks these up and transfers them within the tooling. The product-filled trays are then picked up by the seal plate and lifted against the film. The film and trays are subsequently squeezed against the heated upper tooling, which activates the sealing characteristics against the tray while cutting the film. Finally, after the seal dwell time has elapsed, the seal station lowers the trays again, and the transfer ejects to the machine's out-feed on the following cycle.
Fully automatic tray sealers are ideal for medium to large-scale enterprises. The conveyors that drive the trays through the machine make them totally automatic, reducing the need for operator intervention. The automatic tray sealing machine has a speed of up to 200 packs per minute, making it the quickest tray sealer on the market.
