The work aims to study the effects of pre-stress on the creep property of corrugated paperboard based on a series of experiments, so as to obtain the creep curves of corrugated paperboard. Research experiments had been done with corrugated paperboard under three constant compression loads and four different pre-stresses to obtain its creep curve as well as to compare and analyze the influence made by the pre-stress. The result indicates that pre-stress made a big difference to the creep of corrugated paperboard. Under various pre-stresses, the creep deformations of A corrugated paperboard and BC double corrugated paperboard are different. The creep of corrugated paperboard will become larger with the increase of pre-stress.
