What’s the difference between turntable and rotary tower pallet wrap machines?

Turntable pallet wrapping machines apply the wrap by turning a load on its turntable while the film carriage ascends and descends on a fixed mast.

Rotary tower stretch wrapping machines wrap by rotating the film carriage around a stationary load. Rotary tower machines are better for loads that are very heavy or very light, irregular shaped, fragile or unstable.
