A Heavy Duty Shrink Tunnel is an industrial-grade machine designed to apply heat to shrink film tightly around products or packages, offering a secure, tamper-proof finish. It is built for high-volume production lines and can handle heavy-duty applications, including large or bulky items, multi-packs, or products with irregular shapes. The shrink tunnel uses consistent and controlled heat from either electric or gas-powered heaters, ensuring uniform shrinking of the film. This type of machine is widely used in industries like food and beverage, pharmaceuticals, cosmetics, and manufacturing for wrapping items such as bottles, boxes, or cartons, providing a professional, protective, and presentable finish.
