Corrosion-inhibiting stretch wrap, also called VCI (volatile corrosion inhibitor), is used to wrap machinery, ferrous parts, or other items where corrosion of metal parts is a concern. The wrap creates a barrier that protects parts from ambient moisture, protects parts during shipment, and ensures bundles are secure. Stretch wrap rolls have a continuous length of plastic that is wrapped around the sides of a pallet or bundle to protect the package from dust and moisture, prevent and indicate tampering, and keep items together.
