Summary The objective of this study was to investigate the integrity of aseptic aluminium laminate packages for different filling products after form‐fill‐seal processing using various testing methods. The integrity of the package was found to be influenced by the physical properties of filling product. When soyamilk (watery) was the filling product, the measured currents were lower than 10 μ A for all of the packages subjected to electrolytic testing. If guava juice (high viscosity with high particulate content beverage) was the filling product, a total of 40% of tested packages showed escalation of current to greater than 1000 μ A. This poor integrity was found to have resulted from compromise of the inner layer of packaging because of the particulate content of the juice. It was also demonstrated that the damage to the inner lining of the packages did not lead to the deterioration of the filling product by causing the development of penetrating micro holes. The cyclic voltammetry method is applicable to distinguish whether penetrating micro holes and damage have occurred in the plastic inner layer of a package.
