March 3, 2022 One challenge that metal manufacturers and finishers face is corrosion protection during shipping and storage. Many strategies exist, from coatings and liquid rust preventatives to VCI packaging. The latter has revolutionized the way metals are protected in an enclosed package, replacing greasy rust preventatives with dry corrosion protection. Yet manufacturers with sharp…

Sometimes, VCI papers need an extra barrier against moisture. Normally, this would be provided through the use of a polyethylene coating. Unfortunately, the use of this plastic-based moisture barrier creates an environmental problem as the resulting paper cannot be recycled through normal channels. Once again, Cortec® overcomes this challenge with its EcoShield® VpCI®-144 Barrier Paper that combines…

A silicon steel company needed three months of corrosion protection while shipping silicon steel plates cut to size for use in micro motors. They decided to use VpCI®-146 Paper, cut into 8 x 11 inch (20 x 28 cm) pieces and placed into the small packaging boxes (0.5 ft³ [14 L]) with the steel plate…

When it comes to choosing an anticorrosion packaging material for metals, it can sometimes be a toss-up between selecting VCI paper or VCI film. There is not necessarily one right choice. Much of the decision depends on customer preferences and application needs. Reviewing some of the advantages of Cortec’s own VpCI® Film vs. VpCI® Paper can help…

Moisture barrier paper is a must-have for the packaging industry. Unfortunately, polyethylene (PE) or wax coatings are the traditional means of sealing porous paper to slow the transmission of water vapor. The resulting product presents an environmental problem because it cannot be recycled through normal channels. A fully repulpable barrier material is the answer for…

About 15 years ago, a manufacturer switched from using a liquid rust preventative on brake rotors to sandwiching layers of rotors between precut pieces of CorShield® VpCI®-146 Paper for corrosion protection in-process (WIP cycle) and during shipment. The manufacturer took this to the next level in 2020 when they started using robotics to package rotors for…
