As the two typical structural paper packaging materials, honeycomb paperboard and corrugated fibreboard occupy important position in the field of logistics packaging. Although experts and scholars have carried out numerous research work on properties of the two sandwich paperboards, the agreement about edgewise compressive strength of them has not been reached up to now. The purpose of this study is to investigate the edge effect and the influence on edgewise compressive strength of the two sandwich paperboards by experimental and numerical simulation methods. Firstly, a standard size samples on machine direction(MD) and cross- machine direction(CD) of the two sandwich paperboards were made up and the edgewise compressive strength experiments were carried on. Secondly, with the same material, comprehensive weight and thickness, the finite element models of honeycomb paperboard and corrugated fibreboard were established, and the numerical assessment on edgewise compressive strength of CD and MD of the models were analyzed respectively. Lastly, measures to restrain the edge effect are put forward, and the edge enhancement finite element models of the two paperboards were established. The bulking analysis based on numerical method was carried out. Research shows that the edge effect is one of the main factors affecting the edgewise compression strength of honeycomb paperboard and corrugated fibreboard.
