Aluminium thin foil products are mainly used for food contact materials such as flexible packaging, container and household foils. As the thickness of foil is becoming thinner, the possiblity of occuring some quality problems are increased such as hole, pinhole and scratch.
Heterogeneous grain structure, inter-metallic compounds, undesirable impurities transferred from ceramic foam filters and poor liquid metal refining are some of the reasons for these quality problems of the thin foil material produced by twin-roll continuous casting method. In this study, the root cause of the defects such as intermetallic compounds, Al2O3 and SiO2 particles on the aluminium casted coil surface and their effects on final product quality were investigated. Scanning electron microscope (SEM) and energy dispersive spectrometer (EDS) were used for the characterization of the defects both on the casted coil and thin foil materials.
