When the semi-auto shrink wrap machine is working, products wrapped with film are sent to the shrinking chamber. The heating tube will be electrified to heat the air, which will be circulated in the chamber by a special fan. Under the action of hot air, film will be shrunk and closely attached on the product surface. After that, well packed products will be delivered out of the chamber and the film will be formed by cold air outside. The heat shrinking work is done.

This shrink wrapping machine is easy to operate and is controlled by switches and buttons on the panel of electric control cabinet.
