BENZ Packaging Solutions (P) Ltd. - Gurgaon, Pune, Chennai, Jamshedpur, Delhi, Kolkata, Indore What is VCI ? VCI is an abbreviation for Vapor Corrosion Inhibitor or Volatile Corrosion Inhibitor. These Corrosion Inhibiting compounds are Coated on Paper or Polyethylene Bags, and have sufficient Vapor pressure to release molecules into the air. Due to their polarity, the VCI Molecules are attracted to the surface of Metal, just like a magnet. VCI Molecules move from the Paper or film directly to the surface of Metals. When these compounds come in contact with metal surfaces they form a very thin molecular layer. This thin layer effectively Inhibits Corrosion on the Metal Surface by preventing air and Moisture from coming in contact with the surface of the metal. For More Information;
