What sets Vormek’s tray sealers apart is their flawless performance, high build quality, speed, safety, and precision in MAP execution. Each machine can be customized to meet specific customer requirements and integrated with additional technical components for a complete, turnkey solution.
What Is an Automatic Tray Sealer?
An automatic tray sealer is a machine that packages food products into plastic containers at high speed with minimal manual intervention. MAP technology is a standout feature, extending product shelf life by evacuating ambient air and replacing it with a controlled gas mixture.
How the Machine Works
- Pre-formed containers are loaded—either automatically or manually—into the machine.
- Product is filled—automatically or manually.
- Containers are conveyed into the sealing mold, where sealing is performed (standard or MAP).
- Sealed containers may pass through a jet printer or labeler.
- Finished packages are collected on an exit turntable.
The machine is easily adjustable for different container sizes. Users simply swap the mold to match the container format and apply the necessary settings. Setup and operation are straightforward, thanks to a precise control system and an intuitive, user-friendly software interface.
