Pallet wrapping machines are machines that used to wrap LLDPE stretch film (a plastic film) around a loaded pallet. The stretch film provides extra support while the products being transported or stocked so that they do not tip, spill, or otherwise damage. Additional, the packing cost will be reduced, a more convenient storage and transportation will be achieved and an easier recycle of the packing materials will be conducted with the application of stretch wrapping machines, thus ensuring a less polluted environment. This is currently one of the popular environmental-friendly packing methods. The application of this kind of packing method has extensively covered chemical industry, electronic industry, building materials, home appliances, papermaking, foodstuff & drink etc, especially the container goods transportation in foreign trade.
