VCI (Volatile Corrosion Inhibitor) film is a co-extruded polyethylene packaging film engineered with corrosion-inhibiting compounds embedded within its polymer layers. When heat-sealed or stretch-wrapped around metal parts, VCI molecules continuously vaporize into the enclosed airspace and form an invisible protective layer on every exposed metal surface. This molecular shield interrupts the electrochemical corrosion reaction without leaving any handling or cleaning residue. BENZ VCI Film uses a proprietary 3-layer co-extrusion process — making it particularly critical for Ulsan's industrial environment where Korea Strait salt spray combines with petrochemical ambient fumes (SO2, NOx, and acid gases from the world's largest single-site petrochemical complex) to create an accelerated corrosion environment that is measurably more aggressive than standard coastal conditions. Metal parts stored within 10 km of Ulsan's refinery-petrochemical corridor experience corrosion rates 2-3 times faster than parts in comparable humidity without the chemical pollutant loading.
BENZ VCI Film uses a proprietary 3-layer blown co-extrusion process: inner protection layer, middle VCI reservoir, and outer atmospheric barrier — delivering sustained corrosion protection for up to 3 years.
Single film protects ferrous steel, stainless steel, aluminum, copper, brass, and zinc simultaneously — eliminating the need for separate packaging materials per metal type.
Multimetal, Stretch, Shrink, Bubble, Anti-Static, Bio-Film, Woven Fabric, Non-Woven, and Enviro — matched to equipment size, metal mix, and transit severity.
MIL-PRF-22019E, NACE TM0208, ASTM D1748-02, JIS Z 1535, TRGS 615, RoHS, REACH, and FDA for equipment packaging — accepted by defense, automotive, and aerospace buyers worldwide.
For Ulsan's Hyundai Motor stamping lines, BENZ VCI Stretch Film is the primary pallet-wrap solution for body panels and pressed parts. BENZ VCI Woven Fabric Film protects HHI shipyard fabrications during open-air yard storage. BENZ Multimetal VCI Film bags are recommended for mixed-metal petrochemical valve assemblies where stainless steel, Monel, and carbon steel coexist in a single unit.
High-technology co-extruded blown film protecting ferrous and non-ferrous metals simultaneously. Available in sheets, rolls, 2D bags, and 3D bags.

BENZ VCI Film carries one of the broadest certification portfolios in the industry — covering U.S. military specifications, European environmental regulations, Japanese industrial standards, and food/pharmaceutical equipment packaging approvals.
Ulsan is Korea's largest industrial city by output — the manufacturing geography concentrates along the coast with Hyundai Motor's five-plant campus in the central zone, the HHI shipyard complex and offshore fabrication yards along the eastern waterfront, SK Energy's refinery and petrochemical zone in the south, and the automotive Tier-1 supplier cluster (Hyundai Mobis, Hyundai WIA, Hyundai Transys) distributed across the Ulsan National Industrial Complex in the north. This concentration creates a unique corrosion environment where maritime salt spray overlaps with industrial chemical pollutants — SO2 and NOx from refinery stacks combine with coastal chlorides to produce an accelerated corrosion mechanism that is measurably more aggressive than standard coastal conditions.
The corrosion pattern in Ulsan is shaped by coastal subtropical climate overlaid with heavy industrial pollution — summers bring sustained 30+ degree Celsius temperatures with 80-90% relative humidity; the East Asian monsoon season (June-September) adds heavy rainfall and saturated air; and typhoons (July-October) drive salt-laden winds across the entire manufacturing belt. The most distinctive feature of Ulsan's corrosion environment is the petrochemical ambient — acid gases from SK Energy's refinery complex neutralize standard alkaline-based VCI chemistry faster than in clean coastal environments. BENZ recommends VCI Stretch Film for Hyundai Motor pallet wrapping, VCI Woven Fabric Film for HHI shipyard and offshore fabrications, VCI Shrink Film for marine engine preservation, Multimetal VCI Film bags for petrochemical valve and multi-metal assemblies, and Anti-Static VCI Film for EV power electronics. BENZ VCI Film's proprietary chemistry is specifically formulated to resist neutralization by acid gas exposure — a critical advantage in Ulsan's unique industrial atmosphere.
The performance gap between engineered VCI film and commodity alternatives is significant. Generic films often use single-layer construction with basic VCI compounds that offer limited metal coverage and shorter protection windows. Here is how BENZ compares:
| Parameter | BENZ VCI Film | Generic VCI Film |
|---|---|---|
| Construction | 3-layer co-extruded blown film | Single or dual-layer cast film |
| VCI Reservoir | Dedicated middle layer — sustained release | Surface-applied — depletes quickly |
| Protection Duration | Up to 3 years | 6-12 months typical |
| Metal Compatibility | Multi-metal: ferrous + non-ferrous + alloys | Usually ferrous-only |
| Nitrite Content | 100% nitrite-free (TRGS 615) | Often contains nitrites |
| Military Certification | MIL-PRF-22019E certified | Not certified |
| Anti-Static Option | MIL-PRF-81705D rated ESD film available | Rarely available |
| Environmental | RoHS, REACH, 100% recyclable, Bio-Film option | Varies, often non-compliant |
| Lab Validation | BFSV Germany, Intertek, NACE tested | Self-certified or no testing |
A: BENZ VCI Stretch Film is the standard solution for Hyundai Motor's high-volume stamping lines. Machine-grade rolls run on automated pallet wrappers, creating sealed VCI atmospheres around stacked body panels within seconds of wrapping. The zero-residue formulation ensures panels move directly to body-in-white welding and e-coat painting without affecting paint adhesion or welding quality.
A: Yes. Ulsan's unique corrosion environment — where Korea Strait salt spray combines with SO2 and acid gases from SK Energy's refinery complex — creates conditions that neutralize standard alkaline-based VCI chemistry faster than typical coastal locations. BENZ VCI Film uses a proprietary multi-component formulation with acid-resistant buffering that maintains protective efficacy even in Ulsan's pollutant-loaded atmosphere.
A: BENZ VCI Woven Fabric Film combines VCI corrosion protection with a reinforced woven polyethylene substrate that provides puncture resistance, tear strength, and UV stability for 12+ months of outdoor exposure. For HHI's massive pre-fabricated ship blocks and offshore modules handled by gantry cranes and yard trailers, this tear-resistant construction maintains VCI seal integrity through rough handling that would puncture standard polyethylene film.
A: Yes. BENZ VCI Shrink Film is the standard solution for marine diesel engine preservation at HHI's Ulsan engine works. The heat-shrink process creates a tight, sealed encapsulation that conforms to complex cylinder bore, crankshaft journal, and camshaft geometries — maintaining VCI protection during the 3-6 months between engine machining and vessel installation.
A: Yes. BENZ Multimetal VCI Film is formulated for simultaneous protection of ferrous, non-ferrous, and exotic alloy metals — including Monel (nickel-copper alloy) used in petrochemical valve trim parts. This eliminates the need for separate VCI packaging for each metal type within a mixed-alloy valve assembly, simplifying packaging workflows at Ulsan's petrochemical equipment fabrication shops.
A: Yes. BENZ VCI Film is certified to MIL-PRF-22019E — accepted by Korea's nuclear power supply chain for preservation packaging of reactor vessel internals, steam generator tube bundles, and control rod assemblies. The certificate and lot-traceable documentation required for nuclear-grade packaging is available for every BENZ VCI Film shipment.
