VCI Paper Coating Technology for Paper &
Packaging Manufacturers

NuGRD-BIO™ VCI Paper Coating Technology enables paper mills, coating companies, converters, and packaging manufacturers to produce high-performance corrosion protection paper for industrial, automotive, and export packaging applications. Our bio-based VCI coating technology transforms ordinary kraft paper into value-added VCI packaging paper that helps protect metal components from corrosion during storage, transportation, and international shipping. The technology is amine-free, nitrite-free, and designed to deliver reliable multi-metal corrosion protection while supporting sustainable packaging initiatives.

VCI Additive For Paper Coating: Transform Standard Kraft Paper
Into High-Performance Corrosion Protection Packaging

Traditional kraft paper provides physical wrapping and protection, but it does not prevent corrosion caused by moisture, oxygen, salts, and other environmental contaminants. By incorporating NuGRD-BIO™ VCI additives into a paper coating formulation, manufacturers can create VCI paper that actively protects metal surfaces without the need for oils, greases, or additional rust preventive treatments.

When metal parts are wrapped or packaged with VCI coated paper, the active corrosion-inhibiting molecules gradually release into the enclosed package environment and form an invisible molecular barrier on exposed metal surfaces. This protective layer helps reduce corrosion risks throughout storage, transportation, warehouse handling, and export shipment. The result is a clean, efficient, and sustainable corrosion protection solution suitable for automotive components, industrial equipment, fabricated metal parts, tools, fasteners, bearings, and other metal products.

Our bio-based VCI coating creates an invisible molecular barrier that protects ferrous and non-ferrous metals without oils, greases, or traditional rust preventive treatments. The technology is designed for paper manufacturers seeking environmentally responsible corrosion protection solutions for automotive, industrial, export, and metal packaging applications.

What Is VCI Paper? How VCI Works For Metal Corrosion Protection

VCI (Volatile Corrosion Inhibitor) paper is a specialized corrosion protection packaging material designed to protect metal components during storage, transportation, and export shipment. Unlike conventional packaging paper, VCI paper is manufactured by applying a corrosion-inhibiting coating to kraft paper or other paper substrates, creating an active packaging solution that helps prevent rust and oxidation.

The coated paper continuously releases carefully formulated VCI molecules within an enclosed package environment. These vapor-phase corrosion inhibitors disperse throughout the package and are attracted to exposed metal surfaces, where they form an invisible molecular protective layer. This protective barrier helps isolate the metal from corrosive elements such as moisture, oxygen, salt residues, and atmospheric contaminants that can lead to corrosion.

How VCI Coated Paper Works

When metal parts are wrapped, interleaved, or packaged with VCI coated paper and placed inside a properly enclosed package, the active VCI molecules gradually vaporize from the paper surface and distribute throughout the package atmosphere.

As the molecules reach exposed metal surfaces, they form a microscopic protective layer that inhibits the electrochemical reactions responsible for rust and corrosion. This vapor-phase protection allows VCI technology to protect not only directly contacted surfaces but also recessed areas, cavities, crevices, and other difficult-to-reach locations.

The corrosion-inhibiting action remains active throughout storage, transportation, warehouse handling, and international shipping, helping maintain the condition and appearance of valuable metal products until they reach their final destination.

Advantages of VCI Paper Packaging

Unlike traditional rust preventive oils, greases, waxes, and other temporary coatings, VCI paper provides clean and dry corrosion protection without leaving oily residues on finished components. Parts can typically be removed from the packaging and placed directly into service without additional cleaning or surface preparation.

VCI paper is widely used for protecting:

Automotive components
Bearings and gears
Fasteners and hardware
Industrial machinery parts
Fabricated metal products
Steel, cast iron, copper, brass, and aluminum components
Export packaging and long-term storage applications

By combining physical wrapping protection with active vapor-phase corrosion inhibition, VCI paper provides an efficient, cost-effective, and environmentally responsible solution for modern industrial packaging requirements.
