An orbital stretch wrapper

An Orbital stretch wrapper is a means of applying stretchable "plastic film to a load, consisting of a roll (or rolls) of "stretch wrap supported on a vertical rotating ring and a means of passing a load through the ring's eye horizontally. Several designs are available.[1][2]

The item or load can go through the ring on a "conveyor or can be paced into the ring by a "pallet truck. Small loads can be suspended within the rotating ring by hand. Stretch is achieved by creating tension between the load and film roll using a brake or gear ratio system.
