The method of direct determination of Poisson’s ratio about corrugated paperboard is rarely reported currently. However, traditional Poisson’s ratio test method is difficult to meet the test requirements. In view of the shortcomings of traditional methods, digital image correlation method was adopted to measure the Poisson’s ratio of corrugated board under in-plane static compression. The deformations were recorded of four kinds of corrugated board under in-plane compression. The obtained deformation photos were imported into MATLAB program for processing, so as to obtain the displacement and strain distribution for calculating the Poisson’s ratio under in-plane static compression. The results showed that Poisson’s ratios of E, BS, BD and BC corrugated paperboards were -3.86, -0.42, -2.09 and -1.49 respectively. The showing of negative Poisson’s ratio was mainly related to craft of corrugated paperboards and orientation deformation of fiber during compression. By directly measuring Poisson’s ratio of corrugated paperboards under in-plane static compression, a new way to get Poisson’s ratio of corrugated paperboard was provided. In addition, it could be of reference to packaging material selection and simulation analysis.
