Drop tester was used for diagonal stiffness test of molded pulp pallet. The deformations of specimens in different drop height situations were analyzed to verify the diagonal stiffness. Digital images were obtained by high speed charge-coupled device (CCD) camera, and quantitative analysis the molded pulp pallet was carried out by using digital image correlation (DIC) method. Elastic-plastic mechanical characteristics of the molded pulp pallet was obtained, which was used for quantitative evaluation impact deformation resistance and carrying capacity of pallet. The purpose was to provide guidance for design of molded pulp pallet.
