The work aims todevelop a new general-purpose cushioning structure board to solve the bottleneck problems such as single core paper configuration and limited thickness of a single layer in honeycomb boards due to the limit of technological level. With molded pulp as raw material and hexagonal prism structure as an example, a honeycomb board was designed and processed by combining forward and reverse insertion method, and the finite element method was used for simulation to obtain key structural parameters and related optimal parameter combinations. The pulp molded board with forward and reverse insertion structure had good coupling effect. Its load carrying capacity was greatly improved compared with that of a single layer boards. The board performance was quantitatively analyzed by combining the evaluation indexes of ultimate load and specific energy absorption. The initial compressive load could reach a maximum of 73.7 kN, which met the load carrying requirements of heavy packaging apparatus such as trays. The effect of each structural parameter on the load carrying and cushioning property of the board was known by range and variance analysis. The study showed that the cell wall thickness and the edge length of the middle section had significant effect on the load carrying and cushioning property. The forward and reverse insertion structure solves the bottleneck problems of the existing paper honeycomb material with limited height and thickness and single configuration, and improves the load carrying and cushioning property of the pulp molded honeycomb board, which can meet the heavy load requirements. The same design concept and research method can be used for other regular polygon tapered thin-walled tube cells.
