Fastener Export Packaging for Sea Freight Rust Prevention

Fastener Export Packaging for Sea Freight Rust Prevention

Fastener exports often travel by sea, where high humidity, salt spray and temperature swings cause condEnsation and rust. Proper rust-preventive packaging is essential for export delivery.

VCI Vapor Corrosion Inhibition

VCI paper/film releases corrosion-inhibiting vapor in enclosed spaces, forming a molecular layer on metal. Fasteners stay rust-free for 6-24 months without oil. Export carbon-steel fasteners commonly use VCI bags plus desiccant—ready to use on arrival, saving customer cleaning.

Vacuum and Inner Liners

Higher-grade orders use PE inner bags vacuum-sealed or nitrogen-filled with ample silica gel to keep humidity below 30%. Stainless parts should also be moisture-packed to avoid oxidation spots.

Cartons and Pallets

Outer cartons use 5-ply corrugated or plywood boxes; pallets are ISPM-15 heat-treated with under-layer moisture film. Heavy cargo gets strapping reinforcement. Each carton carries packing list and shipping marks for destination distribution.
