The shelf life of foods and beverages depends among other things on the packaging material used. Metals are ideally suitable for packaging, as they can be laminated with various passivating and food-compatible layers. Electrochemical measurements such as Electrochemical Impedance Spectroscopy (EIS) make it possible to check the layers for damage."}}" id="text-8c3cf42bca" class="cmp-text">
