Abstract [en]

Fracture behaviour of laminated food packaging materials is studied. The materials used in this work were the single layer of Aluminium foil (Al-foil), Low density polyethylene (LDPE) and the lamination of these single layers. Experiments were performed by applying the centred crack specimen as well as the 2-leg trousers specimen. It was observed that the load carrying capacity increased for the tensile and decreased for the tearing specimen when the two layers are laminated together. It was also found that in the case of tearing the crack growth was not only initiated by shear stress but also by normal stress. A modified strip yield model and the essential work of fracture theory were used to analyze the deformation and the fracture behaviour. The initial crack growth of the single layers and the laminate during the tensile and tearing were compared and investigated.
