What is VCI in packaging?
VCI is a class of chemical compounds that emit rust-inhibiting vapors into an enclosed air space . When metal is present, the VCI molecules form a nano-sized layer of protection on the surface of ferrous and non-ferrous metal that displaces moisture and prevents corrosion. At ARMOR, we make the analogy that VCI vapors knit together to form an invisible blanket that covers the surface of metal to shield it from moisture and the damaging effects of rust and corrosion.

How long does armor protective packaging last?
Armor Protective Packaging® corrosion management products provide approximately three years of protection for metal parts and surfaces when used properly in normal warehouse conditions. To ensure successful results, parts must be completely wrapped or enclosed – airtight packaging is the most effective for best results and longest protection time. Variable conditions such as temperature and humidity extremes, airflow, production and process methods, surface conditions of metal to be protected, customer employee training and other factors are impossible for ARMOR to control so it is impossible to guarantee a specific length of protection. Contact your ARMOR representative for details related to your specific application.
What is armor VCI?
When you wrap or enclose a metal part in an ARMOR VCI product, VCI vapors are released and they attach themselves to the surface of metal to form a nano-sized layer of protection that repels water, moisture and other contaminates that cause corrosion. Traditional rust preventatives such as oil and grease offer a physical barrier to protect the surface of metal parts, but they are messy, time consuming to apply and remove, and are harmful to humans and the environment. Vapor corrosion inhibitors (VCI), such as ARMOR VCI Nanotechnology, work on a molecular level and they are clean, dry, easy-to-apply, and VCI protection dissipates once metal part is removed from VCI packaging, which eliminates the need for removal.

Can VCI be used for packaging?
The good news is both products can be used in packaging programs to leverage the benefits of each type. For example, a container could be lined with a VCI gusset bag and individual parts can be wrapped in paper to stabilize them in shipping. A combination of VCI Poly sheeting or VCI Kraft Paper could be used for interleaving between layers. Interleaving with either material increases the saturation levels of VCI and ensures it reaches all spaces of the container.
What is VCI paper used for?
Packaging – One of the first widespread uses for VCIs was VCI paper which was used to wrap parts for transportation and/or storage. The technology then evolved with the development of VCI film, where the inhibitor was incorporated into Polyethylene film. (8). This offered the advantage that parts could be stored in the VCI film without any rust -preventative (RP) oil, which would typically have to be removed before part was placed into service. In places where the VCI film is in direct contact with the metal, VCI molecules adsorb on the metal surfaces, creating an invisible molecular barrier against corrosive elements such as oxygen, moisture, and chlorides. As VCI molecules vaporize out of the film and diffuse throughout the package, they also form a protective molecular layer on metal surfaces not in direct contact with the film. When the packaging is removed, the VCI molecules simply vaporize and float away. (12) VCI films protect metals both through direct contact and vapor action. Large Equipment/Assets are wrapped in VCI heat shrinkable film for long term outdoor storage. The use of polymer films for thorough protection of electronic equipment during shipment or storage should take into account the prevention of electrostatic discharge (ESD), corrosion, and the disposal of the film after use. A main property that makes an polymer film a viable packaging material for electronic equipment is the film’s ability to eliminate electrostatic discharge. The most recent property addition to VCI film is biodegradability . (12)

What is the effect of VCIs on metal?
Once the VCIs have adsorbed on the surface of the metal, they provide an effective barrier that is hydrophobic and prevents moisture from getting through to the metal surface. Consequently, this prevents the formation of a corrosion cell and renders the moisture ineffective (13).
What is pipeline preservation?
Pipeline preservation (internal) - VCIs are seeing widespread application for the mitigation of corrosion of the internal surfaces of new and/or existing out-of-service pipelines. (9) Top-of-the-line TOL corrosion typically occurs in wet gas pipelines that have a stratified flow regime and poor thermal insulation. TOL corrosion is predominantly a problem of protection in the gas phase (15). Tests showed that the best potential for providing corrosion protection for TOL came from azoles, certain acetylene alcohols, and a "green" volatile aldehyde. (16)
