Which is a better rust inhibitor, VCI Paper or VCI Poly?
From strictly a corrosion inhibitor standpoint, paper has been a better inhibitor of rust due to the way that the VCI is impregnated into the paper, and is released into the air and onto the product. VCI Papers have been in existence for over 50 years, first adopted by the United States Military. VCI because of paper characteristics is able to protect a part quicker coming off of a paper, than it is off of polyethylene. This is not to say that VCI Poly is not an excellent product or that it does not have its place. However, from a pure rust inhibitor issue, paper has proven over the long haul to be slightly more effective.
