The work aims to review the latest research progress of wood-based functional composite materials, focusing on the preparation technology and characteristics of functional wood such as superphobic wood, transparent wood, super wood and metallized wood. Through deep literature research, the main categories of wood-based functional composites were systematically sorted out, and the preparation process and unique performance advantages of each functional wood were described in detail. On this basis, the potential application value of these functional woods in the field of packaging was further discussed, aiming at providing a useful reference for the innovative design of new packaging materials. The wood-based functional composite materials had excellent performance in mechanical strength, protective properties, dimensional stability, electrical conductivity, thermal conductivity, flame resistance and electromagnetic shielding, and they could meet the requirements of modern packaging materials on strength, durability and environmental protection. Therefore, wood-based functional composite materials, with their unique performance advantages, have shown great development potential and market space in the field of packaging.
