Aluminium Foil Corrosion
IPS Industrial Packaging Solution supplies coloured, lacquered or printed aluminium foil, to be used in the manufacturing of processed cheese packaging. Our lacquered foil has a superior resistance to corrosion: Porosity Test and Electrochemical Impedance Spectroscopy (EIS) prove that IPS foil has a corrosion resistance 1000 times higher than the average market material.
The Porosity test has simulated 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. The samples have been in contact with aggressive solution for 1 hour at room temperature.
Electrochemical Impedance Spectroscopy has evaluated the corrosion resistance of a substrate in contact with an aggressive solution such as NaCl 3,5% w/w (water solution). Impedance at 0.02 (Picture A) and phase angle close to 90° (Picture B) represent values for an excellent corrosion resistance.
Advantages of IPS Aluminium Foil:
- Extended product’s shelf life
- Excellent corrosion resistance
- Highly customizable
- Total protection against light, moisture, oxygen and gas
