By utilizing the unique constant temperature and uniform temperature diffusion characteristics of steam, it can achieve an unparalleled effect compared to ordinary electric infrared heating shrinkage machines. The equipment uses a heater to heat water and generate steam, without the need for an additional steam boiler. The host has two main and auxiliary heaters, which can adjust the power of the equipment according to different production speeds. The conveyor belt adopts stepless speed regulation, and the conveying speed can be adjusted arbitrarily. Widely used in large barrels or small bottles of mineral water and purified water; Used in the food and beverage industries such as soda and tea drinks, as well as in occasions where shrink wrap packaging is required for cosmetics, shampoo, and hardware electronics. The heat shrink machine uses shrink film to wrap around the product or packaging, and after heating, the shrink film shrinks and wraps tightly around the product or packaging, fully displaying the appearance of the item, improving the product's marketability, increasing aesthetics and value
