1. We usually use steel pallet for packing. Then, arrange the products neatly.
2. Then fix it with a special packing strap to prevent displacement during transportation.
3. After the fixing is completed, wrap layers of plastic film to protect the product from damage.
4. Load it into the container by forklift, and fix the container inside again after packing, so as to avoid the internal impact during shipping as much as possible.
