CorShield® VpCI®-146


CorShield® VpCI®-146 is made from neutral natural kraft paper coated with Vapor phase Corrosion Inhibitors for superior corrosion protection of both ferrous and non-ferrous metals. The paper doesn’t contain any nitrites, phosphates, or silicates. It is excellent for single item packaging, interleaving, shipping tube end closures, or sheet liners. Using CorShield® VpCI®-146 is simple and easy; just wrap your products inside and fold the edges of the paper together. Fully recyclable/ repulpable.


CorShield® VpCI®-146 with EcoBio® Technology is the premium corrosion inhibiting paper in the industry. It relies on Cortec’s patented biodegradable and compostable Vapor phase
Corrosion Inhibiting Technology, which has revolutionized the way metals are protected in an enclosed package. Both sides of CorShield® VpCI®- 146 paper offer effective protection to ferrous and nonferrous metals, eliminating the need to stock a variety of papers for different metal types. Simply wrap items in the paper and fold the edges together, taping as needed to hold paper in place. The VpCI® coating on the paper vaporizes, reaching all metal surfaces within the package to provide complete corrosion protection with a very thin, very effective VpCI® layer that does not alter product appearance or require removal before further finishing or use.

CorShield® VpCI®-146 paper is made from 100% recycled content paper and is fully recyclable/ repulpable. It is biodegradable and compostable It contains 92% USDA certified biobased content and is a qualified product under the mandatory federal purchasing initiative of the USDA BioPreferred® Program.*
