Sealing frames
A sealing frame for a thermoforming or tray sealing machine is a component that holds the tray or packaging materials in place during the sealing process. It typically consists of a rectangular aluminum frame with a flexible seal on the underside. When pressure is applied, this seal forms a tight closure against the top of the tray, ensuring proper sealing.
The sealing frame is positioned above the heating element and tray cutter and is lowered onto the tray during the sealing process. This creates a tight seal around the edge of the tray to prevent leaks or contamination. The size and shape of the sealing frame are determined by the size and shape of the tray or packaging being used.
Sealing frames that match your packaging solution
A sealing frame is made from aluminum. It is manufactured using computer-controlled CNC machines that precisely cut and shape the material according to the desired specifications. The use of CNC manufacturing ensures a high level of accuracy and consistency in the production process, which is crucial to ensure that the sealing frame fits snugly in the machine and functions properly. Once the material is processed, additional finishing processes such as plating are carried out to enhance the durability and resistance to wear and tear of the sealing frame.
