Automatic Tray Sealing Machine

Gas Flushing: After the vacuum sealing process, the machine can introduce a specific gas or gas mixture into the tray or container. This is commonly done to replace the removed air with a modified atmosphere that helps further extend the product's shelf life. The gas used is typically a mixture of nitrogen, carbon dioxide, and/or oxygen, depending on the specific requirements of the product being packaged.

Sealing: Once the vacuum and gas flushing steps are completed, the machine applies heat to seal the tray or container. This ensures that the package remains airtight and prevents any leakage or contamination.

Cutting: Some machines also have cutting capabilities, allowing them to trim excess packaging material or create easy-open features on the sealed tray or container. This feature enhances the convenience and usability of the final product.
