Resumo
Three main requirements are mandatory in order to achieve
optimal quality in canned food: adequate processing of the product,
definition of the preserving method, and a correct alloy for the
deposit. Lacquer coatings are applied on food cans to enhance
corrosion protection and also with decorative purposes. In this
investigation, steel coated with a Cr3+ based treatment layer and
polyethylene teraphtalate polymeric film (PET), applied by coextrusion, was characterized by electrochemical impedance
spectroscopy (EIS) measurements, in NaCl 0.5 M solution, to
evaluate the coating corrosion resistance in this environment. The
experimental results showed that this new material (tin free) has
good corrosion resistance regardless of the porosity found in the
polymeric film, indicating that it can be a non-polluting alternative
to replace tinplate and hexavalent chromium conversion layer in
the food industry, being compatible with the packed product.
