VCI Square-Bottom Bags are 3D rust-preventive packaging designed for medium and large metal components. The square bottom design, combined with multi-layer VCI co-extruded film, prevents stress concentration at the base. This design improves load-bearing capacity and stacking stability.
The bags provide moisture-proof sealing and physical protection, ensuring safe long-term storage and cross-border shipping for complex industrial workpieces.
The bottom is seamless and forms one strong piece. It supports heavier loads than traditional folded-edge bags, reducing cracks during stacking.
The square shape allows efficient storage and easier logistics management. It optimizes warehouse space and makes stacking more secure.
These bags offer both vapor-phase and direct contact protection. VCI vapor reaches intricate shapes, recessed areas, and internal surfaces. Meanwhile, the bag itself shields metal from moisture and dust.
Parts can be used immediately after unwrapping. No cleaning or degreasing is needed, saving time and labor costs.
By preventing rust, these bags reduce scrap, rework, and returns. Easy-to-use bags also streamline operations, increasing ROI.
Made from non-toxic materials, these bags are safe for users and the environment. They replace greasy oils and coatings.
Clear material allows quick visual inspection without compromising protection. This facilitates checking and sorting items.
Durable PE material can be heat-sealed or closed with tape, ensuring a secure semi-sealed or fully sealed package.
VCI Square-Bottom Bags protect metal components across industries:
Automotive & Machinery: Engine parts, valves, bearings, tools, and full machinery.
Electronics & Electrical Equipment: Circuit boards, connectors, control panels, and precision parts.
Aerospace & Defense: Aircraft parts, avionics, and ammunition.
Hardware & Metalworking: Fasteners, stamped parts, hand tools, and castings.
Industrial Supplies: Pumps, motors, and spare parts during storage or transit.
How do these bags work?
VCI compounds vaporize inside the bag, forming a thin protective layer on all metal surfaces, including recessed areas, preventing corrosion.
Are they suitable for all metals?
Yes. The bags protect steel, iron, copper, brass, aluminum, chromium, zinc, and alloys. Specialized guidance is available for sensitive metals or electronics.
How should I package for best results?
Clean and dry metal parts.
Wear gloves to prevent contamination.
Place items inside the bag and seal with heat or tape.
Use heavier gauge film for sharp edges.
Shelf life?
Store in original packaging, in a cool, dry place away from sunlight. Shelf life is 1–3 years. Use promptly for full protection.
Can the bags be reused?
For full protection, use a new bag per cycle. Once opened, VCI vapor escapes and protection decreases.
Minimum Order Quantity (MOQ)?
Contact sales for MOQ based on your requirements and bag specifications.
