Aluminium can be employed in food packaging thanks to its remarkable corrosion resistance. Aluminium protects food against light, moisture, oxygen and environmental contamination. More than this it extends products shelf life and preserves their flavours.
Aluminium corrosion in food packaging
Aluminium foils produced by IPS – Industrial Packaging Solution can be used in the manufacturing of processed cheese packaging, from 25g up to 500g portion and have an excellent corrosion resistance. Porosity Test and Electrochemical Impedance Spectroscopy (E.I.S) prove that IPS foil has a resistance 1000 times higher than the average market material.
Aluminium corrosion resistance tests
Porosity Test simulates the corrosive attack of the processed cheese in contact with the lacquered aluminium. Corrosion is the cause of black spots and pinholes on the surface of aluminium foil. E.I.S evaluates the resistance to corrosion of a substrate in contact with an aggressive solution. These tests show that IPS Industrial Packaging Solution lacquered foils guarantee the highest corrosion resistance and protect cheese from environmental contamination.
