Removal of Corrosion Resistant Polymeric Coatings from Metal CansNon-destructive method and system for removing the polymeric coating from metallic food cans The Need Corrosion-resistant polymeric coatings are widely used in metal cans, providing an effective barrier against gases, light, and microorganisms. However, between the canning process and foodstuff properties, corrosion can still occur despite ongoing research to further improve corrosion-resistant packaging. Part of the challenge lies in a reliable method of removing these coatings without altering their properties at the time of analysis in order to better understand how the protective coatings are performing against corrosion.
The Technology Our technology is an electrochemical removal of corrosion-resistant polymeric coatings from metal cans. It involves an innovative electrochemical cell with an electrolyte solution enclosed in a non-conductive vessel. By applying a carefully controlled current to the metallic surface of the food container, the technology efficiently and precisely delaminates the polymeric coating without affecting its chemical composition.
