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 Hyundai Motor, Hyundai Heavy Industries shipyard, petrochemicals, and offshore platforms in Ulsan where coastal Korean humidity with monsoon and typhoon moisture exposure 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 Ulsan's Hyundai Motor Company assembly plant, Hyundai Heavy Industries shipyard components, SK Energy and S-Oil refinery equipment, and HD Korea Shipbuilding & Marine Engineering offshore platforms, we recommend BENZ VCI Plain Paper for high-volume Hyundai automotive stamping interleaving and BENZ HD Reinforced VCI Paper for heavy shipyard and offshore platform structural fabrications.
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.
Ulsan is the world's largest single-site industrial city — home to Hyundai Motor Company's flagship assembly complex (producing over 1.5 million vehicles annually), Hyundai Heavy Industries' shipyard (the world's largest single shipyard), SK Energy and S-Oil refineries, and HD Korea Shipbuilding & Marine Engineering's offshore platform construction. This extraordinary concentration of automotive, shipbuilding, petrochemical, and offshore manufacturing creates massive demand for corrosion protection across every product category BENZ manufactures. Ulsan's coastal location on the Sea of Japan creates aggressive salt-spray corrosion conditions, with monsoon humidity from June-September and typhoon moisture surges. For Hyundai Motor's high-volume stamping operations, VCI paper consumption runs to thousands of rolls monthly for interleaving body panels, structural stampings, and powertrain components between press shop and body-in-white assembly. For the shipyard, steel plates measuring up to 25mm thick and 12 meters long need VCI protection during multi-month construction schedules where partially completed hull sections sit exposed to maritime weather.
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 marine hardware, 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 is effective for stampings, gears, brackets, fasteners, and boxed machined components that need clean, residue-free protection through warehouse holding and outbound logistics. Multi-metal grades are also available where aluminum, plated hardware, and steel share one pack.
A: Yes, provided the paper type and pack design match the environment. Ulsan's risk comes from salt-laden air, humidity, and industrial exposure rather than one single factor, so barrier-backed grades and correct enclosure design matter more than light kraft separation alone.
A: Yes. HD Reinforced Paper is usually preferred where modules are heavier, edges are sharper, or the pack will be handled repeatedly during project staging or port movement. It improves toughness without giving up dry corrosion protection.
A: Yes. BENZ supports qualification and supply discussions for buyers across the wider Ulsan 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, coastal yards, or export freight. We will recommend the right BENZ VCI paper format and sample route for your qualification run.
