PAO1820 Automatic Rotating Arm Stretch Wrapper

PAO1820 Automatic Rotating Arm Stretch Wrapper


The rotating arm wrapping machine is mainly suitable for the case where the product has high stability requirements and the packaging efficiency is high.

The packaging of the arm stretch wrapper is completed by the rotary arm around the pallet. In this process, the pallet does not move, so the scattering and dumping of the goods during the packaging process are not easy to occur.

In addition, the arm can reach a higher speed according to the packaging efficiency requirements, for example, 60 pallets per hour, 80 pallets per hour.

The main advantage of our arm rotating wrapping machine is that the speed is the world's leading industry, the fastest can reach 45 rpm, achieve double arm design, achieve 120 pallets per hour packaging efficiency.

The upper breaking mechanism of the equipment is designed and developed with German partners, with excellent working stability and effect. It is very beneficial for the application of the automatic warehouse entry.
