Study on the Failure Mode of Corrugated Paperboard during Transport and Distribution

Corrugated paperboard is a kind of inexpensive and environmental-friendly packaging material and may be made into cushioning package pads to protect products from damaging during transport and distribution. By virtue of the static compression tests with four kinds of different compression speed for two kinds of corrugated paperboard pads, this paper obtains the failure modes and the stress -strain curve. The results show that the failure of the corrugated board exhibit four stages, the linear elastic stage, the yield stage, plastic deformation and densification stage. The damage of corrugated structure pads occurs on yield and plastic deformation stage and structure damage mostly is shear crimpling on core layer. The damage of double layer corrugated paperboard appears separately. First the bottom layer is damaged following the top layer until the corrugated paperboard is damaged wholly. In addition, we also fmd that the static compression speed has not significantly influence on properties of the corrugated paperboard.
