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, marine equipment, automotive components, and steel processing in Busan where coastal maritime humidity with typhoon-season moisture surges 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 Busan's Hyundai Samho shipyard hull sections, Hanjin Heavy Industries marine propulsion components, and Korea's third-largest port handling steel plate and structural steel, we recommend BENZ HD Reinforced VCI Paper for heavy ship plate fabrications and BENZ Poly-Coated Laminated VCI Paper for precision marine engine components stored in typhoon-season coastal humidity.
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.
Busan is South Korea's premier port city and shipbuilding hub, home to major dockyards that build commercial vessels, naval combatants, and offshore platforms. The city's marine engineering cluster manufactures propulsion systems, shaft assemblies, rudder components, and marine engine internals that require extended corrosion protection during construction fitting-out schedules that can span 12-18 months. Korea's third-largest port handles massive volumes of steel plate, structural sections, and pipe for the domestic construction and shipbuilding industries. Busan's coastal maritime climate produces aggressive corrosion conditions: salt-laden air from the Korea Strait, typhoon-season humidity surges, and temperature cycling from hot, humid summers to cold, damp winters. For shipyard components, BENZ VCI Paper provides protection that is compatible with downstream marine paint systems — the VCI molecules dissipate completely upon unwrapping, leaving surfaces ready for primer application without solvent cleaning or mechanical re-preparation that damages precise surface profiles.
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 Poly-Coated Laminated VCI Paper is usually the safest starting point because it combines vapor protection with a real moisture barrier. It is especially useful when the cargo may sit in coastal warehouses, terminals, or containers before final delivery.
A: Yes. Marine-service hardware is a strong use case for BENZ VCI Paper because it protects machined ferrous surfaces without leaving greasy residue. For bores, threads, and cavity geometry, BENZ VCI Crepe Paper is often added inside the component.
A: Yes. Fabricated machine parts, housings, brackets, and mixed-metal assemblies can be packed in BENZ VCI Plain Paper for indoor movement or upgraded to poly-coated and reinforced grades when the route includes harsher export exposure.
A: The main trigger is repeated exposure inside the coastal logistics chain. Humid air, typhoon-season rain, container dwell, and condensation between outdoor yards and indoor storage can start rust well before the cargo finishes its international route.
A: Yes. BENZ supports qualification and supply discussions across the wider Busan port-industrial system. The final recommendation changes according to metal type, storage duration, and whether the parts remain indoors or move through terminal and coastal handling.
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 route includes warehouses, terminals, container dwell, or longer sea freight. We will recommend the right BENZ VCI paper format and sample route for your qualification run.
