The working principle of the stretch wrapping machine is to place the packing object in the center of the turntable, start the rotation of the turntable motor, and naturally drive the turntable to rotate, so that the object realizes the peripheral winding film machine.

At the same time, the elevator motor also starts, and the wrapping machine drives the film stretch wrapping carriage. The whole assembly moves up and down to reach the wrapping in the height direction of the object, which realizes the wrapping and packaging of the entire surface of the object. This is not only conducive to the storage, transportation and packaging requirements of mechanized loading and unloading operations, but also prevents damage to the goods during the handling process, plays a role of dust-proof, moisture-proof and cleaning, also reduces production costs and improves production efficiency.

The main thing in the wrapping process is the adjustment of the film tension and the film penetration. Generally, the film tension can be achieved by adjusting the rotation speed of the turntable and the rotation speed of the motor. The pre-stretch ratio is  also adjustable through the frequency converter which connected with the motor of film carriage.

The M shape pallet wrapping machine is suitable for places where using pallet jack or pallet trucks transfer goods and cannot be installed in pit of the ground. The equipment entry and exit station is close to the ground, and there is no need to use a ramp to enter and exit the goods, which is convenient for pallet jack to transport high-height goods.
