Cushioning particle board was prepared using hemp haulm as raw material, which was the residue of hemp fiber production. Orthogonal experiments were carried out with different density, sizing dosage, and thickness, and performance of the particleboard was tested. The application performance of the particleboard as cushion packaging material was analyzed. The results showed that the particleboard has the characteristics of light mass and color when hot-pressing temperature at 175 ℃ and using piecewise hot-pressing process; when the sizing dosage is 10%, static bending strength and elastic modulus is the best; when σ>190 N/cm2, the particleboard has lower buffer coefficient and can substitute for EPE as cushioning packaging material.
