Which VCI Paper Works for Busan and Ulsan Manufacturing?
VCI paper releases a corrosion-inhibiting vapor around clean metal inside a closed wrap, carton or bag. Plain paper interleaves gears, stampings and flat machine parts. Crepe paper wraps irregular valves and marine hardware. Laminated paper adds moisture resistance for humid storage and port dwell. HD reinforced paper handles heavy ship-machinery parts and sharp edges.
Korea's weather service reports average humidity around 78-79% in July and August, with a southern rainy season lasting about 31 days. Coastal warehouses and temperature changes between plant, truck and port can condense moisture on metal. VCI paper must therefore be treated as part of a closed pack, not as an exposed sheet.
