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 (SAIC, Tesla Gigafactory), electronics, semiconductor equipment, and steel in Shanghai where Yangtze Delta humidity with intense summer heat and plum rain season 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 Shanghai's Tesla Gigafactory producing 851,000 EVs annually, SAIC's new energy vehicle supply chain, Lingang chip packaging plants, and ZF Group Asia-Pacific remanufacturing operations in Yangshan Free Trade Zone, we recommend BENZ VCI Plain Paper for high-volume automated interleaving in Tesla and SAIC press shops, and BENZ Poly-Coated Laminated VCI Paper for container exports via Yangshan Deep-Water Port where Yangtze Delta humidity and 'plum rain' season create intense condensation inside ocean containers.
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.
Shanghai's Lingang Special Area has become a global automotive manufacturing epicenter. Tesla's Gigafactory produced 851,000 electric vehicles in 2025 — over 50% of Tesla's global deliveries — and is a vital global export hub. In February 2025, Tesla's Megapack energy storage battery factory in Lingang (its first outside the US) commenced operations, producing 10,000 Megapack units (40 GWh) annually. The broader Yangtze River Delta achieves a highly integrated '4-hour industrial circle' for new energy vehicles, with approximately 80% of critical components and materials sourced locally within the SAIC-anchored supply chain. In March 2026, a specialized chip packaging and testing plant for automotive electronics and robotics was launched in Lingang. ZF Group inaugurated its Asia-Pacific remanufacturing headquarters in the Yangshan Free Trade Zone in mid-2025. This concentration of advanced manufacturing faces a specific corrosion challenge: the Yangtze Delta's 'plum rain' season (梅雨, June-July) brings weeks of continuous high humidity that causes aggressive condensation inside factories, warehouses, and especially inside sealed ocean shipping containers. Shanghai hosts the annual International Corrosion and Rust Prevention Technology and Equipment Expo, reflecting the city's acute awareness of corrosion costs. BENZ VCI Paper provides the dry, clean, vapor-phase protection this ecosystem demands — no liquid residue, no contamination risk for precision EV battery and electronics components.
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: For bonded storage and port logistics, BENZ Poly-Coated Laminated VCI Paper is usually the safest choice because it adds a real moisture barrier on top of vapor protection. Where the component has internal cavities, machined bores, or sealing faces, BENZ VCI Crepe Paper is often added inside the part.
A: Yes. BENZ VCI Plain Paper and multi-metal grades are useful where metal fixtures, precision components, plated parts, and mixed-material assemblies need dry protection without oily residue before inspection or final use.
A: Yes. BENZ VCI Paper is well suited to brackets, fasteners, valve hardware, pump parts, machined housings, and boxed industrial components that need clean corrosion protection through warehouse holding and outbound logistics.
A: Shanghai combines hot humidity, rain, river-sea air, and seasonal storms. Condensation can also form when metal moves between climate-controlled interiors and warmer docks or warehouses, which is enough to start flash corrosion on sensitive surfaces.
A: Yes. BENZ supports qualification and supply discussions across the wider Shanghai industrial belt, with the final recommendation changing by metal type, storage duration, and whether the parts remain indoors or move through bonded or port-linked yards.
A: No. BENZ VCI paper is designed as a dry corrosion-protection material, so parts unwrap cleaner than they would after oil-based preservation. That matters for inspection, assembly, and export presentation on high-value industrial hardware.
Tell our packaging team what metals you pack, how the parts move, and whether the exposure is bonded warehousing, export staging, monsoon humidity, or port-linked handling. We will recommend the right BENZ VCI paper format for your qualification run.
