Shrink Tunnel 4535 is a packaging machine designed to shrink heat-sensitive films like PVC, POF, or PE tightly around products using controlled heat. The product wrapped in shrink film passes through the tunnel, where hot air circulates evenly to shrink the film snugly, providing a secure, leak-proof, and attractive package. This machine is widely used in the food packaging, cosmetics, pharmaceuticals, and consumer goods industries. It helps improve product presentation, protection, and shelf life. It operates with adjustable temperature and conveyor speed to suit different packaging needs.
