This thesis work was based on the enhancing of 3-dimensional forming of paperboard tray package by adopting line creasing pattern and analysis of the results with the help of mathematical modelling and simulation. The aim of the project is to improve convertibility of paperboard blank in tray forming by replacing linear creased pattern around the corner areas. The paperboard with and without creases was modelled and their relevant stresses, total strain and plastic strain was compared. Two different paperboards named single ply
and multiply paperboard were simulated. The comparison revealed that the creases improved the performance and convertibility of paperboard by reducing stiffness. The reaction force from paperboard blank on female die was calculated and curve follows the experimental behavior measured with the help of four sensors. The project was sponsored by Stora Enso and lasted for six months.
