Abstract
C-flute corrugated paperboards with length of 100mm were combined side by side with/without water soluble glue to study the static edgewise crush property. Combinations with different height (20, 25, 40, 60, 80, and 100mm), different number of layers, with or without glue were tested to obtain mechanical property and buffering property data of C-flute corrugated paperboard. The result indicates that the deformation of paperboard combinations can be divided into three stages as elastic-like deform stage, yield-like stage and high plastic deformation stage. The mechanical model of the elastic-like deform stage was built according to numerical fitting, which shows that the relationship between the stress and the quadratic function of strain is exponential.
