Use of impedance spectroscopy techniques in the study of corrosion resistance of peel-off aluminum foil lids for the packaging of pureed food

This work examines the chemical and morphological properties of the different types of aluminum foil lids used for packaging pureed fruit and vegetables (thickness, porosity and type of lacquer applied), their resistance to corrosion when in contact with simulant solutions and influence of the presence of residual air inside food packages.
