Paper-based packaging routes including corrugated, honeycomb, paper cushioning and responsible sourcing discussions where product-specific evidence supports the claim.
VCI paper is kraft or specialty paper impregnated with vapour corrosion inhibitors for wrapping and interleaving metal parts. This guide explains what VCI paper is, how interleaving works, which grade to choose (plain, crepe, HD reinforced, poly-coated), how it differs from VCI film, and how to pack so protection actually holds in storage and export.

VCI paper is paper (usually kraft or a specialty paper construction) treated with volatile / vapour corrosion inhibitors. When clean, dry metal is wrapped or interleaved with the paper and held in a closed package, the paper releases inhibitor vapour that adsorbs on metal surfaces and slows or stops rust. Paper also separates stacked parts so they do not scratch each other. Parts typically unpack dry, without oil wipe-off. VCI paper is not a substitute for a sealed outer bag on long humid routes; it is the contact and interleaving layer inside a proper closed system.
VCI paper carries inhibitor chemistry in or on the fibre web. In a closed box, bag or crate, two things happen at once:
1. Contact protection. Where paper lies against metal, inhibitor is available at the interface immediately. That is why interleaving every layer matters for stacked plates, stampings and machined blanks.
2. Vapour protection. Inhibitor also leaves the paper into the small air spaces around the part. It reaches edges, holes and faces that the sheet does not fully cover, as long as the package is closed and the paper stays near the metal (industry guidance often keeps VCI material within about 300 mm; closer is better).
Paper alone does not create a strong moisture barrier. On humid ocean routes, best practice places VCI paper against the metal, then closes a VCI film bag or aluminium barrier system with desiccant as required. Science background: how VCI works. Definition hub: what is VCI packaging.
Catalogue entry point: VCI paper products. RFQs that cite military wrapping practice often reference MIL-PRF-3420 class language for VCI paper; always match claims to the certificate of the exact grade you buy.
Interleaving is the highest-value use of VCI paper in stamping, machining and spare-parts programmes.
Stacked plates trap moisture films and allow fretting abrasion. VCI paper both separates the faces and supplies inhibitor. Skipping layers is a common cause of centre-of-stack staining even when the outer wrap looks correct.
Highest-reliability export packs often use both: paper on the metal, film as the sealed outer. Film deep dive: VCI film guide.

To wrap and interleave metal parts so vapour corrosion inhibitors protect surfaces during storage and shipping, usually without oil, while also preventing metal-to-metal abrasion in stacks.
Inhibitor chemistry in the paper contacts metal and also vaporizes into closed package air, adsorbs on surfaces, and slows rust. The pack must stay closed for vapour concentration to hold.
No. Ordinary kraft has no corrosion-inhibitor loading. Only treated VCI paper provides vapour-phase protection.
For short dry internal moves, paper in a closed carton can be enough. For humid export and long storage, add a sealed VCI film bag and often desiccant and barrier.
Follow the grade instruction. Many papers are designed for two-sided use; some coated grades have a preferred active face. When in doubt, keep treated paper in direct proximity to metal and avoid blocking layers.
Use a multimetal VCI paper grade. Ferrous-only paper can be the wrong chemistry for mixed-metal kits.
Depends on grade, seal, climate and metal condition. Correctly closed systems are commonly designed for months of protection; open cartons and wet parts fail early. Shelf life of unused rolls is typically shorter than sealed service life of packed goods.
MIL-PRF-3420 is a U.S. military performance specification family widely used as a commercial reference for VCI-treated wrapping papers. Match any MIL claim to the certificate of the exact product supplied.
Yes for interleaving and wrap. Contact plus nearby vapour is the design intent. Do not isolate paper from metal with inert plastic sheets that block both contact and vapour.
