Shrink Tunnel Machine

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.Shrink tunnels are temperature controlled environments used to tighten shrink film that has been applied by a shrink wrapper around products. Conveyor systems move packages through the oven, allowing for an even application of heat.Heat shrink works by creating a protective seal around an electrical wire or connection. It is made from a substance that shrinks in diameter when heated creating a secure seal. It is used in electrical work to protect wires, terminals and connections against moisture and abrasion.
