shrink tunnel
A shrink tunnel is a device used in packaging to apply heat to shrinkable materials, typically plastic films. When products are wrapped in these films and passed through the tunnel, the heat causes the material to contract tightly around the item, providing a secure and protective seal. This process is commonly used in industries like food packaging and consumer goods.
The shrink tunnel operates by using hot air or steam to evenly distribute heat around the wrapped products. This ensures that the shrink film adheres properly, enhancing the appearance and durability of the packaging. It is often part of a larger packaging line that includes equipment like shrink wrappers and conveyors.
