Poly VCI Paper

Product Structure:

The VCI Poly Paper product features a structure in which a VCI is coated onto the interior of a kraft paper substrate. The outer layer consists of a polyethylene film, which provides additional water vapor barrier capabilities, ensuring that the material maintains stable protective performance even in high-humidity environments. The product has a basis weight of 110 g/m² and is available in a maximum width of up to 2420 mm, making it suitable for the packaging of large-sized metal products or for meeting bulk packaging requirements. This product is an acid-free, pH-neutral material that is non-corrosive to metal surfaces, making it ideal for use with industrial products that require high standards of surface integrity.

Key Advantages:

1. VCI Poly Paper features a VCI+PE structure, providing dual-layer protection.

2. VCI Poly Corrosion Paper is more durable than standard VCI paper.

3. The outer PE layer of VCI Poly Industrial Paper effectively blocks moisture penetration.

4. Poly VCI Packaging Paper utilizes acid-free, neutral materials, posing no risk of corrosion to metals.

5. No cleaning or secondary processing is required after using VCI Poly Industrial Paper.

Application Scenarios

VCI Poly Kraft Paper is widely utilized across industries such as mechanical manufacturing, metal processing, automotive components, and export trade, serving as an effective anti-rust packaging solution for steel, aluminum, and various other metal products. It is particularly well-suited for scenarios where both moisture protection and packaging strength are critical considerations—such as maritime exports, long-distance transportation, and storage in high-humidity environments. VCI Poly Kraft Paper can be employed either to individually wrap single items or as a liner material within sealed packaging systems, thereby enhancing overall protective performance.

Product Specifications and Supply Capabilities

VCI Poly Paper is available in two forms—rolls and sheets—in a brown color, with a standard basis weight of 110 g/m² and a maximum width of up to 2420 mm. The standard lead time for orders is 14 days, and custom sizes and specifications can be provided to meet specific customer requirements. Under standard storage conditions, the product has a shelf life of 3 years.

Client Collaboration:

A Southeast Asian steel trader has long sourced CVCI's VCI Poly Paper as its primary internal packaging material, utilizing it in conjunction with sealed packaging methods. Through the dual-action mechanism—combining VCI vapor-phase protection with a moisture-resistant PE layer structure—the risk of moisture ingress and metal corrosion has been effectively minimized. Across numerous consecutive shipments, the products consistently maintained excellent surface condition upon arrival at the destination port; the rust-prevention performance remained stable, successfully meeting protection requirements for a duration exceeding one year, and significantly reducing both quality-related issues and after-sales costs.

Instructions for Use:

• Ensure that the metal surface is clean, dry, and free of contaminants prior to packaging.

• VCI Poly Corrosion Paper must be applied in close contact with the metal surface.

• For regularly shaped items, it is recommended to fully enclose the product and seal the seams.

• It may be utilized as a liner or interlayer within a sealed packaging system.

• Wear gloves during handling to prevent contamination.

Laboratory and Technical Capabilities

CVCI is equipped with a specialized anti-corrosion materials laboratory capable of conducting VCI release performance tests, moisture-resistance tests, and environmental simulation experiments, thereby ensuring product stability under actual shipping and storage conditions. Drawing upon years of accumulated technical expertise, the company continuously optimizes its VCI formulations and composite structures to enhance the materials' adaptability across diverse application scenarios.
