Fracture Toughness Analysis of Aluminum (Al) Foil and Its Adhesion with Low-Density Polyethylene (LPDE) in the Packing Industry

Liquid food packages consist of various polymers films, which are bonded together with Aluminum foil (Al-foil) using adhesion or by direct heat. The main aim this research was to define important material properties such as fracture toughness and some FE-simulation model parameters damage initiation, evolution, the between Al-foil low-density polyethylene (LDPE) film. This investigation is based on both physical experiments FE simulations in ABAQUS without initial cracks different lengths for comparison purposes. final used compare numerical input an extensive study ambition investigate materials’ cases laminates. Finally, relation theoretical experimental results linear elastic mechanics modified strip yield were shown, calculated two thicknesses Al-foil.
