What is a Shrink tunnel?

A shrink tunnel is a heating device used to shrink and tightly seal shrink film around packaged products. After the product is covered with the film, it passes through a tunnel-shaped heating zone, causing the film to heat-shrink and conform to the product. Heat sources include electric heaters, hot air, or gas, and the device is widely used in industries such as food, beverages, pharmaceuticals, and electronics. Shrink wrapping offers excellent product protection, improves appearance, prevents contamination, and stabilizes products during transportation. It is particularly efficient in mass production lines, as it can handle a variety of product sizes with adjustable speed and heat settings.
