Creasing and folding of paperboard are important converting operations in manufacturing of packages. A two-dimensional finite element simulation of multiply paperboard that was creased and folded was presented, and the numerical results were compared with experimental data. The paperboard material model was defined by a combination of an anisotropic elastic-plastic continuum model with isotropic hardening and a softening interface model. Based on experimental observations of variations of properties in the thickness direction of the paperboard, a material mapping method was proposed to define the material parameter in the models. The tilted double notch shear test technique was used to measure the shear strengths for the paperboard interfaces. The material model and data were validated by simulations of the creasing process. Folding simulations were done for both paperboard machine direction and cross machine direction, to two crease depths, 0.0 mm and 0.2 mm. The simulation results were compared with experimental results, where the bending moment-rotation angle curve from the simulation and experiments showed good agreement.
