Introduction Aluminium foil is extensively used in the packaging industry due to the outstanding properties of the metal. Its primary role is to serve as a barrier against oxygen, light, moisture and microorganisms, thereby protecting food and pharmaceuticals from degradation. The explosion of thin aluminium foil coils is associated with the entrapment of gas or […]

Introduction Aluminium is a highly reactive metal that oxidises readily. Because of its strong affinity for oxygen, it quickly forms a thin, adherent and impermeable layer of aluminium oxide (Al₂O₃), which serves as a protective barrier against corrosion. However, when this layer is broken, corrosion can begin either in a localised area or on the […]
