From the table we can see that:
wooden pallets are the most cost-effective and are the most commonly used pallets in most general cargo transportation currently;
plastic pallets are suitable for pharmaceutical and chemical industries due to their better environmental adaptability, and their high strength also makes them the best choice for long-term use.
Plywood pallets are slightly lower in strength than wooden pallet, but they do not require fumigation when exported and are cheaper than wooden pallet, so they are suitable for international light cargo shipping;
metal pallets are used in the machinery manufacturing industry due to their ultra-high strength;
paper pallets are cheap, but have low strength and are suitable for one-time light cargo transportation.
