VCI Paper For Steel

Why does steel need VCI packaging material?

Steel rusts easily because its main component, iron, is highly chemically reactive in the natural environment. This process is significantly accelerated in high humidity (e.g., relative humidity exceeding 60%), frequent temperature fluctuations, or maritime environments, leading to red or white rust on the steel surface. This not only affects appearance but can also reduce product performance, increasing the risk of rework and customer complaints. CVCI's VCI anti-rust paper continuously releases vapor-phase corrosion-inhibiting molecules within the packaging space, forming a molecular-level protective film on the metal surface, inhibiting oxidation reactions at the source. No oiling or additional cleaning processes are required, providing long-term protection for steel during transportation, warehousing, and export.

Corrosion inhibitors are key to providing durable protective coatings for steel, preventing oxidation from occurring at its source.

Product model:

• SF/H (PO, WO, PA, WA)

• PO: plain paper, non-composite structure PA: plain paper, single-sided lamination structure.

• WO: crepe paper, non-composite structure WA: crepe paper, single-sided lamination structure.

Application range of VCI paper: 

Our VCI paper has excellent anti-rust protection effect on ferrous metals such as carbon steel, alloy steel, cast iron, phosphated steel, blue steel, powder metallurgy, oriented and non-oriented silicon steel, and aluminum. This series of VCI packaging paper releases corrosion-inhibiting gas to form a protective layer without contacting the metal surface, effectively preventing rust. The product is widely used in VCI paper in military industry, machinery manufacturing, auto parts, electrical equipment, hardware tools and other industries, especially for metal products that need to be exported or stored for a long time. We provide Anti Corrosion VCI Paper for steel in a variety of structures and sizes, which is an environmentally friendly, practical and economical VCI paper for steel and VCI paper solution.

How to store VCI paper?

Our VCI paper should be stored in a dry, cool, well-ventilated environment and kept sealed to avoid direct sunlight and moisture. During handling and use, the original packaging bag should be kept from damage to prevent the anti-rust effect. The product has a shelf life of three years from the date of manufacture. The performance is stable during the validity period and is suitable for long-term anti-rust packaging. To ensure the anti-rust effect, it is recommended to seal as soon as possible after using VCI packaging paper, VCI paper, VCI packaging paper for steel or VCI Paper for steel for packaging, and avoid frequent opening and closing to prevent the vapor phase corrosion inhibitor from volatilizing and becoming ineffective. 

FAQ:

1. What types of steel is this VCI rust-proof paper suitable for?

Suitable for various ferrous metals such as carbon steel, alloy steel, cast iron, silicon steel, and phosphated steel. It can also be used for the protection of some aluminum materials. It is widely used in the packaging of steel coils, steel plates, and mechanical parts.

2. Does it have moisture-proof capabilities?

The product can enhance its moisture-proof performance through a PE coating, providing waterproof and moisture-proof functions.

3. What structural types are available?

Common structures include PO (plain paper), PA (single-sided laminated), WO (crepe paper), and WA (reinforced laminated). Different types can be selected according to packaging strength and moisture-proof requirements.

4. What is the minimum order quantity and delivery time?

The standard MOQ is 300kg. The delivery cycle for regular orders is approximately 7–14 days, which can meet bulk purchasing and customization needs.

5. Does it require cleaning or degreasing after use?

No. VCI rust-proof paper is an oil-free rust-proof solution. Metal can be used or assembled directly after unpacking, saving cleaning steps and improving efficiency.
