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.

Here's a general overview of how a typical semi-automatic cup sealing machine works:

• Preparation: The cups or containers to be sealed are manually filled with the desired product. The cups are then placed on the machine's platform or tray.
• Sealing Process: the cup is positioned under the sealing mechanism. The sealing mechanism can vary depending on the specific machine, but it typically involves applying heat to seal the film onto the cup. This can be done through methods such as heat sealing, induction sealing, or pressure sealing.
• Sealing Operation: The user initiates the sealing process by pressing a button. The sealing mechanism then engages and seals the film onto the cup. The machine has a timer or sensor to control the sealing time or temperature, depending on the sealing method used.

Here's a breakdown of the machine's features:

• Vacuum Sealing: The machine creates a vacuum inside the tray or container by removing the air, which helps in preserving the product. Vacuum sealing prevents the growth of bacteria and molds, reduces oxidation, and maintains the product's quality.

Here's how a rotary type MAP tray sealing machine typically works:

• Trays Placement: The machine is equipped with a rotating platform or carousel that holds multiple trays. Empty trays are placed onto the platform in a predetermined pattern.
• Tray Filling: If required, the trays can be filled with the desired product manually or automatically before sealing. The filling mechanism can vary depending on the specific application.
• Modified Atmosphere Packaging: Once the trays are filled, the machine creates a modified atmosphere inside each tray. This is achieved by replacing the air within the tray with a specific gas mixture, typically a combination of oxygen, carbon dioxide, and nitrogen. The gas mixture is carefully selected based on the product being packaged to optimize shelf life.
• Sealing Process: After the trays are filled and the modified atmosphere is created, the sealing process begins. The machine uses heat and pressure to seal the trays, ensuring a secure closure to maintain the modified atmosphere and prevent any leakage.
• Trays Discharge: Once the sealing process is completed, the trays are discharged from the machine and can be further processed, labeled, and prepared for distribution.
