The work aims to study the properties of wood-plastic composites made of plastics instead of traditional adhesives and their application characteristics in the field of packaging. The eucalyptus veneer was used as raw material and hot pressed. The influence of hot pressing temperature and plastic type on the sheet properties was analyzed by single factor experiment. The finite element model of the packaging pallet was established by Ansys Workbench software. The force and bearing characteristics of the packaging pallet under static bending conditions were analyzed. The optimized hot pressing temperature of the wood-plastic composite sheet was 180 ℃. The sheet made at this temperature could meet the requirements of class II plywood. The wood-plastic pallet prepared by the 9-layer composite sheet was affected by the contact point between the upper connecting plate and the middle panel of the pallet under static load. The left and right sides were broken points, and the maximum stress occurred at the contact position between the upper connecting plate and the middle panel. The sheets prepared by HDPE and PVC films instead of traditional adhesives meet the national standards, and they can be used as raw materials for packaging pallets.
