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 shipbuilding, steel manufacturing, petrochemicals, and semiconductor equipment in Kaohsiung where tropical maritime climate with typhoon-season humidity spikes 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 Kaohsiung's CSBC Corporation shipbuilding hull sections, China Steel Corporation coil storage, CPC Corporation refinery components, and TSMC's Kaohsiung semiconductor fab expansion, we recommend BENZ HD Reinforced VCI Paper for heavy ship plate steel, BENZ VCI Plain Paper for steel coil interleaving, and BENZ Poly-Coated for typhoon-season maritime storage at Taiwan's largest 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.
Kaohsiung is Taiwan's industrial powerhouse — home to CSBC Corporation (Taiwan's largest shipbuilder, constructing naval vessels and commercial carriers), China Steel Corporation (the nation's integrated steelmaker), CPC Corporation (petrochemical refining), and increasingly TSMC's new advanced semiconductor fabrication facilities. The Port of Kaohsiung is Taiwan's largest, handling the majority of the island's steel imports, petrochemical products, and heavy machinery exports. The city's tropical maritime climate creates severe corrosion conditions: year-round humidity averaging 75-85% RH, typhoon-season moisture surges from June to November, and salt-spray exposure from the Taiwan Strait that accelerates unprotected steel corrosion rates. For CSBC's shipbuilding operations, VCI paper must protect heavy steel plates, machined shaft components, and precision marine equipment during construction schedules spanning years. For China Steel's coil and plate storage, VCI interleaving prevents surface corrosion that leads to rejection of otherwise premium-quality material.
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 coastal 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 Paper is well suited to steel accessories, flanges, fasteners, valve hardware, pump parts, and boxed machined components that need clean corrosion protection through warehouse holding and outbound logistics.
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: Kaohsiung combines tropical humidity, warm air, rain, and coastal chlorides. Condensation can also form when metal moves between air-conditioned 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 Kaohsiung industrial belt, with the final recommendation changing by metal type, storage duration, and whether the parts remain indoors or move through coastal 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 long the parts remain stored, and whether the load moves through indoor warehousing, humid docks, or export freight. We will recommend the right BENZ VCI paper format and sample route for your qualification run.
