Shrink Tunnel Machines

A shrink tunnel or heat tunnel is a heated tunnel mounted over or around a conveyor system. Items (such as packaging) have shrink film loosely applied; with heat, the film shrinks to fit snugly around the wrapped object.A shrink tunnel utilizes a conveyor and heat to maintain consistent temperatures within the tunnel chamber. Shrink tunnels are most often used for heat shrink packaging items, but can also be used for curing applications as well. The three primary types of shrink tunnels are recirculating, infrared, and steam tunnels.
