VCI (Volatile Corrosion Inhibitor) paper is industrial kraft paper chemically impregnated with corrosion-inhibiting compounds that vaporize at room temperature. When wrapped around metal parts or used as interleaving material inside sealed packaging, VCI molecules sublimate into the enclosed airspace and form an invisible protective layer — just one to two molecules thick — on every exposed metal surface, including recesses, threads, bores, and cavities that liquid coatings cannot reach. This molecular shield disrupts the electrochemical reaction between metal, moisture, and oxygen that causes rust, tarnish, and white corrosion. When unwrapped, VCI molecules dissipate harmlessly within minutes, leaving parts completely clean and ready for assembly, painting, or inspection without any degreasing or solvent washing. BENZ VCI Paper, manufactured using patented Propatech VCI Technology from Italy, provides multi-metal protection for up to 5 years when combined with BENZ desiccants and aluminium barrier film — making it particularly critical for automotive manufacturing, steel production, agricultural machinery, and petrochemicals in São Paulo where tropical humidity with intense summer rainfall accelerates metal degradation.
BENZ VCI paper uses Propatech chemistry from Italy and is manufactured on virgin kraft substrates for reliable vapor-phase corrosion protection.
Parts unwrap clean for assembly, inspection, painting, or export receipt without the degreasing cycle that oil-based rust preventives create.
Plain VCI paper, poly-coated laminated grades, crepe paper, and HD reinforced paper let buyers match protection level to geometry, humidity, and transit risk.
Our core VCI paper range is positioned around MIL-PRF-3420H, TRGS 615, RoHS, and REACH expectations that matter in export supply chains.
For São Paulo's Volkswagen and Stellantis automotive assembly corridors in the ABC industrial region, Gerdau and ArcelorMittal long-steel product storage, and Embraer aerospace supply chain components, we recommend BENZ VCI Plain Paper for automotive stamping interleaving at São Bernardo do Campo and BENZ Poly-Coated Laminated VCI Paper for monsoon-season steel and machinery exports via Santos port.
Dual-side impregnated kraft paper for wrapping, interleaving, and carton lining where buyers need fast vapor release and clean, economical corrosion protection.

The real decision is whether the paper matches the metal mix, corrosion severity, outer pack design, and receiving-plant expectations. BENZ positions its paper range around dry protection, low residue risk, export practicality, and standards language that global buyers recognise.
São Paulo is Latin America's industrial capital, with the greater metropolitan area's ABC industrial region (Santo André, São Bernardo do Campo, São Caetano do Sul) hosting Brazil's densest concentration of automotive manufacturing — Volkswagen, Stellantis, Mercedes-Benz trucks, and Toyota all operate major assembly and powertrain plants. Gerdau, the largest steelmaker in the Americas, and ArcelorMittal Brazil process and distribute long-steel and flat-rolled products through São Paulo's logistics network. Embraer, the world's third-largest commercial aircraft manufacturer, headquartered nearby in São José dos Campos, sources precision-machined aerospace components from the São Paulo supply chain. Brazil's tropical climate creates intense corrosion conditions: São Paulo's altitude moderates temperatures, but proximity to Santos port (Latin America's largest) means components in transit face Santos' coastal humidity averaging 80-85% RH with heavy summer rainfall. Inside ocean containers departing Santos, differential heating creates 'container rain' — condensation dripping from container ceilings onto packed metal parts — requiring BENZ Poly-Coated's moisture barrier protection layer.
Not all VCI papers are equal. The VCI compound source, kraft substrate quality, and impregnation process directly affect protection duration, metal compatibility, and residue behavior. Here is how BENZ compares to generic commodity VCI paper:
| Parameter | BENZ VCI Paper (Propatech) | Generic VCI Paper |
|---|---|---|
| VCI Compound Origin | Patented Propatech from Italy | Generic Chinese or domestic compounds |
| Protection Duration | Up to 5 years (with barrier system) | 6–18 months typical |
| Metal Compatibility | Multi-metal: ferrous + non-ferrous + alloys | Usually ferrous-only |
| Nitrite Content | 100% nitrite-free | Often contains nitrites |
| Residue on Parts | Zero residue — parts are assembly-ready | May leave oily film or staining |
| OEM Approvals | VW, BMW, Skoda, Volvo, GM | Typically none |
| Military Certification | MIL-PRF-3420H certified | Not certified |
| Environmental Compliance | RoHS, REACH, TRGS 615, 100% recyclable | Varies, often non-compliant |
| Lab Testing | BFSV Germany, ILF, Intertek validated | Self-certified or no testing |
| Kraft Substrate | 100% virgin kraft, dual-side impregnated | Recycled kraft, single-side spray |
A: BENZ VCI Plain Paper is usually the most efficient choice for interleaving flat parts, fasteners, and boxed machined components. Where storage is longer, wetter, or tied to export movement, BENZ Poly-Coated Laminated VCI Paper is usually the safer upgrade.
A: Yes. Auto parts, machine components, tooling, bearings, and mixed-metal assemblies are strong use cases for dry VCI protection because receiving teams generally want clean parts for inspection or assembly rather than oily temporary coatings.
A: The main trigger is condensation. Humid summer air, heavy rain, and temperature changes between storage, trucks, and loading docks can leave enough moisture on bare metal to start flash corrosion, even without direct coastal exposure.
A: Yes. Poly-coated grades are usually the safer option when the route includes longer storage, wetter handling, or additional movement toward export consolidation where humidity exposure is harder to control.
A: Yes. BENZ supports qualification and supply discussions across the wider Sao Paulo industrial belt, with the final recommendation changing according to metal type, pack density, storage duration, and route exposure.
A: Yes. BENZ can send sample rolls or cut sheets so the paper grade, GSM, and format are checked against the real part geometry, box design, and logistics route before a recurring program is finalized.
Tell our packaging team what metals you pack, how the parts move, and whether the exposure is indoor warehousing, humid road transport, multi-stop distribution, or export dispatch. We will recommend the right BENZ VCI paper format for your qualification run.
