ZERUST®, a division of Northern Technologies International Corporation (NTIC), invented Vapor Corrosion Inhibitor (VCI) poly packaging. In 1979, NTIC became the first company to develop and patent polyethylene film with vapor corrosion inhibitor (VCI) technology. This breakthrough created the world’s first VCI poly packaging.

Before this invention, companies protected metal parts with oils, greases, and heavy coatings. ZERUST® changed that. By adding safe VCI molecules directly into polyethylene film, ZERUST® made it possible to protect metal parts during storage and shipment without messy coatings or extra steps. This innovation created an entirely new category of corrosion protection.

For more than five decades, ZERUST®/NTIC has continued to improve VCI polymer technology through active R&D, global laboratory teams, and real-world customer testing. Today, ZERUST® remains the original inventor and global leader in VCI poly packaging, supplying high-performance films, papers, diffusers, and corrosion-management systems to customers in more than 70 countries.
