VCI (Volatile Corrosion Inhibitor) film is a co-extruded polyethylene packaging film engineered with corrosion-inhibiting compounds embedded within its polymer layers. When shrink-wrapped over marine fabrications or stretch-wrapped around palletized components, VCI molecules saturate the enclosed airspace and form an invisible protective layer on every exposed metal surface — including weld heat-affected zones, flame-cut plate edges, and deep internal pipe bores. BENZ VCI Film uses a proprietary 3-layer co-extrusion process with a dedicated VCI reservoir layer — critical for Busan's shipbuilding and port logistics environment where East Sea and Korea Strait salt spray, subtropical monsoon humidity exceeding 80% RH during summer, and typhoon-season moisture surges create extreme corrosion acceleration on stored steel fabrications and marine equipment.
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 Busan's shipyard steel fabrications, BENZ VCI Woven Fabric Film provides puncture-resistant heavy-duty wrapping for hull sections and structural weldments. BENZ VCI Shrink Film encapsulates marine engine blocks and turbine assemblies during quayside staging. BENZ VCI Stretch Film wraps automotive stamping pallets moving between Gyeongsang supplier plants and Busan port-area staging warehouses.
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.
Busan's industrial geography stretches along the southeastern Korean coastline — from the Gijang precision manufacturing zone in the northeast, through the Sasang and Gangseo heavy industry districts in the western metropolitan area, south to the massive Busan New Port and Gamcheon container terminals, and extending along the coast toward the Geoje shipyard corridor. This coastal industrial belt places virtually every manufacturing and logistics facility within direct exposure to Korea Strait salt air — creating a corrosion environment significantly more severe than inland Korean centers like Changwon or Daegu.
The corrosion challenge in Busan is shaped by coastal subtropical climate — hot, humid summers with sustained 80-90% relative humidity and temperatures exceeding 30 degrees Celsius; a wet monsoon season (June-September) bringing heavy rainfall and saturated air; and a typhoon season that drives salt-laden winds deep into warehouse facilities. Even winter months maintain 50-60% RH with frequent coastal fog events. The most dangerous corrosion condition occurs during seasonal temperature transitions (March-April, October-November) when day-night temperature swings cause severe condensation on stored metal masses. BENZ recommends VCI Woven Fabric Film for shipyard steel fabrications, VCI Shrink Film for marine engines and export equipment, VCI Stretch Film for automotive CKD pallet wrapping, Multimetal VCI Film bags for marine valves and mixed-metal assemblies, and Anti-Static VCI Film for electronic naval equipment. All grades are NACE TM0208-2008 tested and compatible with Korean KS standards.
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 Woven Fabric Film is the primary solution for shipyard fabrications. Its reinforced woven substrate provides the puncture resistance, tear strength, and UV stability required for hull sections, structural blocks, and pipe spools stored outdoors in Busan's salt-spray coastal environment. Standard polyethylene VCI film would puncture during crane handling — woven fabric film maintains VCI seal integrity through rough handling cycles.
A: Yes. BENZ VCI Shrink Film creates a tight, sealed encapsulation around large engine blocks that conforms to complex cylinder bore, bearing saddle, and crankcase geometries. The sealed VCI atmosphere provides continuous protection for up to 3 years — sufficient for the months-long gap between engine machining completion and vessel installation at Busan shipyards.
A: Automotive CKD pallet loads staged in Busan port-area warehouses face 80-90% RH and direct salt exposure — conditions that initiate flash rust on stamped steel panels within hours. BENZ VCI Stretch Film creates a sealed VCI microenvironment around palletized CKD parts that neutralizes humidity and salt exposure during the staging, container stuffing, and ocean transit phases.
A: Yes. BENZ VCI Film is certified to MIL-PRF-22019E — the U.S. military specification for transparent VCI barrier materials. This certification is recognized by the Republic of Korea Navy procurement chain for naval weapon system housings, submarine components, and defense equipment preservation packaging.
A: March-April and October-November seasonal transitions create large day-night temperature swings — daytime warming followed by nighttime cooling causes moisture to condense on metal surfaces that have greater thermal mass than the surrounding air. A 12-degree temperature drop can deposit enough moisture on a steel surface to initiate pitting within hours. BENZ VCI Film prevents atmospheric moisture from reaching the metal surface during these critical condensation events.
A: No. BENZ Multimetal VCI Film delivers zero-residue vapor-phase protection. VCI molecules dissipate within minutes of package opening, leaving valve seats, sealing surfaces, and threaded connections completely clean. This is critical for Busan's marine valve manufacturers where any surface contamination would affect pressure-test performance and marine classification society acceptance.
