Vapor Corrosion Inhibitor Bag | Anti-Corrosion Guide
October 12, 2023
Corrosion is a silent enemy of manufacturing. In Malaysia’s humid tropical climate, metal parts stored in warehouses or shipped to customers can begin rusting within days without proper protection. For automotive, electronics, and industrial equipment manufacturers, corrosion damage means rejected shipments, unhappy customers, and significant financial losses.
A VCI ziplock bag supplier provides the solution: specially engineered bags that release corrosion-inhibiting vapours to protect metal surfaces. HAIN Packaging is a trusted VCI ziplock bag supplier in Malaysia, serving manufacturers across automotive, electronics, aerospace, and industrial sectors with high-quality corrosion protection packaging.
Key Takeaways
- VCI ziplock bags release corrosion-inhibiting vapours that form a protective molecular layer on metal surfaces
- Unlike oils and greases, VCI protection requires no application or clean-up — just place parts in the bag and seal
- Available in various sizes with resealable ziplock closures for repeated access
- Effective on multiple metals including steel, iron, copper, brass, and aluminium
- HAIN Packaging has been a trusted VCI packaging supplier in Malaysia for over 13 years

What Is a VCI Ziplock Bag?
A VCI (Vapour Corrosion Inhibitor) ziplock bag is a specialised polyethylene bag infused with chemical compounds that vaporise slowly over time. When metal parts are placed inside the bag and sealed, these VCI molecules travel through the air and adsorb onto all exposed metal surfaces, creating a protective layer only a few molecules thick.
This molecular layer interrupts the electrochemical reaction between moisture, oxygen, and the metal surface that causes rust. The protection is self-replenishing — every time the bag is opened and resealed, the VCI molecules continue to protect the contents. Unlike traditional rust prevention methods that require messy oils or greases, VCI bags provide clean, dry protection with no application or clean-up required.

Industries Served by Our VCI Ziplock Bags
- Automotive Parts Manufacturers: Brake components, engine parts, transmission parts, and body panels require VCI protection during storage and shipping. Our bags protect against rust for 12-24 months.
- Electronics and Electrical: Circuit boards, connectors, sensors, and precision electronic components benefit from VCI bags with anti-static properties for dual protection against corrosion and electrostatic discharge.
- Aerospace and Defence: High-value aerospace components require the highest level of corrosion protection. Our VCI bags meet stringent industry standards for long-term storage.
- Machinery and Industrial Equipment: Large tooling, dies, moulds, and machine parts stored in warehouses for extended periods need sustained VCI protection.
- Metal Fabrication: Sheet metal, pipes, rods, and fabricated metal products stored before further processing or shipping to customers.
VCI Ziplock Bags vs. Traditional Rust Prevention
| Method | Effectiveness | Labour | Clean-up |
|---|---|---|---|
| VCI Ziplock Bag | Excellent | Minimal | None |
| Rust-preventive Oil | Good | High | Required |
| Grease Coating | Good | Very High | Required |
| Desiccants | Moderate | Low | None |
How Long Does VCI Protection Last?
The duration of VCI protection depends on film type, storage conditions, and package integrity. Our standard VCI ziplock bags provide 12-24 months of protection in typical warehouse conditions. For extended storage up to 5 years, heavy-duty VCI bags with higher inhibitor concentration are available. The resealable ziplock design maintains protection even when bags are opened and closed multiple times, making them ideal for inventory that requires periodic access.
Sizes and Specifications Available
Our VCI ziplock bags are available in a wide range of sizes to accommodate different part types and quantities. Standard sizes include 100x150mm for small electronic components, 200x300mm for medium-sized parts, 300x400mm for larger automotive components, and 500x700mm for industrial equipment parts. Custom sizes can be manufactured to your exact specifications. Film thickness options range from 50 to 150 microns depending on the weight and sharpness of the parts being stored.
The ziplock closure on our VCI bags is designed for repeated use. Unlike heat-sealed bags that must be cut open and cannot be resealed, our ziplock bags allow warehouse staff to access parts, remove what they need, and reseal the bag to maintain VCI protection for the remaining contents. This makes them ideal for service parts inventory, quality control samples, and tools that are regularly accessed.
Proper Usage Guidelines for Maximum Protection
To get the best results from your VCI ziplock bags, follow these guidelines. Ensure parts are clean and dry before placing them in the bag — oil, grease, and moisture on the part surface can reduce VCI effectiveness. Remove as much air as possible before sealing to maximise VCI concentration. Store sealed bags in a clean, dry environment away from direct sunlight and extreme temperatures. For best results, use VCI bags within 18 months of manufacture and avoid exposing them to ammonia, acids, or other chemicals that may neutralise the inhibitor.
Case Study: How a Malaysian Manufacturer Saved RM 180,000 with VCI Bags
A mid-sized automotive parts manufacturer in Johor was shipping brake components to buyers across Southeast Asia. Despite using oil coating and desiccant packs, they experienced rust-related claims on 8% of shipments — costing over RM 200,000 annually in replacements and lost business. They switched to custom-sized VCI ziplock bags from HAIN Packaging. Within 12 months, rust claims dropped from 8% to under 0.5%. Labour time for rust prevention was reduced by 80%. Total packaging cost increased by only RM 0.03 per part, while claim savings exceeded RM 180,000. The switch paid for itself within the first quarter.
Environmental and Safety Benefits
VCI ziplock bags offer environmental advantages over traditional rust prevention methods. Unlike oil and grease coatings that require solvent-based clean-up and generate hazardous waste, VCI bags are clean and dry. The VCI compounds used in our bags are non-toxic and biodegradable. The polyethylene film is recyclable. Additionally, VCI bags eliminate the need for workers to handle messy rust-preventive compounds, improving workplace safety and reducing labour costs associated with application and removal of traditional coatings.
Frequently Asked Questions
Q: What is the minimum order quantity for VCI ziplock bags?
A: Our MOQ for standard VCI ziplock bags is 1,000 pieces. Custom sizes and specifications may have different minimums.
Q: Can VCI bags protect mixed metal assemblies?
A: Yes, our VCI formulations protect ferrous and non-ferrous metals including steel, iron, copper, brass, aluminium, and galvanised surfaces.
Q: Are VCI bags reusable?
A: VCI ziplock bags can be reused as long as the zippe
Q: Are VCI bags reusable?
A: VCI ziplock bags can be reused as long as the zipper remains functional. However, VCI concentration decreases over time, so protection duration decreases with each reuse.
Q: Do you provide samples?
A: Yes, free samples of standard VCI bags are available for testing. Contact us to request samples.
Q: How long does production take?
A: Typical production time is 14-21 working days from order confirmation.
