Modelling the Effect of Barrier Layers on the Tensile Properties of Paperboard Materials for Liquid Packaging

Investigations of the mechanical behaviors paperboard packaging materials has propelled to forefront industries owing anisotropic behavior materials. Paperboard undergo tensile forces during creasing and folding operation. Therefore, knowledge material properties it is undeniably important perform operation without tearing layers. Anisotropic required be addressed for used effectively efficiently. being in nature have different Machine Direction (MD) Cross (CD). The paper focuses on modelling double layered paperboards with barrier elements either aluminum or Ethylene vinyl alcohol copolymers (EVOH). A numerical model was developed LS-DYNA environment showing good fitting physical tests.
