ASA50 Auto Rotary Arm Wrapper with Top Dispenser

Fully Auto Pallet Wrappers

ASA50 is a fully automatic rotary arm stretch wrapper with top sheet dispenser. It’s an ideal wrapper to integrate into a palletizing line to achieve automatic pallet packaging. The rotary arm rotates around a stationary load. It’s a safe and highly effective way to wrap very light, tall, heavy or unstable loads. Apart from wrapping the sides of the load, it also place a piece of PE sheet onto the top of the load to make it water-proof. It provides maximum protection to the products. It has 3 working modes: wrapping only, wrapping with top cover, or bypass. One can choose the most suitable working mode viewing the product being processed.
