建立了一种用循环伏安法测定含铝箔的无菌纸板层压包装完整性的方法。该方法的能力，以识别针孔所产生的裂纹在塑料内层进行了论证。当应用循环伏安法时，由于暴露的铝层处的化学反应，当电压大于0.6V时观察到峰值电流。此外，在具有穿透针孔的封装中，针孔形成允许离子流出封装的离子通道。本研究表明，循环伏安法是适用于区分无菌纸板层压包装含铝箔的缺陷。
A method was developed to determine the integrity of aseptic paperboard laminate packages containing aluminium foil using the cyclic voltammetric method. The ability of the method to identify pinholes arising from cracks in the plastic inner layer was demonstrated. When a cyclic voltammetric method was applied, a peak current was observed when the voltage greater than 0.6V due to the chemical reaction at the exposed aluminium layer. Moreover, in packages with penetrating pinholes, the pinholes formed an ion channel which allowed ions to flow out of the package. This study demonstrates that cyclic voltammetry is applicable to distinguish between the defects of aseptic paperboard laminate packages containing aluminium foil.
