Print quality has always been a point of strong concern among printers and consumers. Metalized films have gain a wide spread popularity among printers because of its low cost and high usages in food packaging applications. But sometimes corrosion spoils the printed products causing huge financial loss to the printers or customers.This paper throws light on major causes of corrosion on metallized films and possible remedies for the same. The metallized films with polyester base were base coated

After 5 days of printing corrosion was examined and possible causes were analysed. The results indicated that excess moisture was the most vulnerable factor contributing to corrosion. Improper pH of glue was found least contributing factor to the corrosion.
