VCI Shower Caps has its unique elastic bottom. The elastic band provides a secure fit over totes or odd-shaped or protruding parts such as hub assemblies. Tote Covers prevent corrosion by diffusing Vapor Corrosion Inhibitor (VCI) chemistry. The covers also act as a barrier of protection against dirt, dust, smoke and other contaminants. The covers are typically made of High-Density Rust-x VCI Film, but the Tote Covers can be made from almost any Rust-X film product as required by the application. They are designed to cover most common sizes of plastic stackable totes and are reusable when in good condition.
