Metal parts packaged in Eco-Corr Film® receive ongoing protection against salt, excessive humidity, condensation, moisture, and aggressive industrial atmospheres. In addition to serving as a physical barrier to the elements and inhibiting corrosion on metals in direct contact with the film, Eco-Corr Film® also contains Vapor phase Corrosion Inhibitors that vaporize and then condense on all accessible metal surfaces within the enclosed package to interrupt the corrosion reaction between metal, oxygen, and an electrolyte.
