VCI Kraft Paper

Product Introduction:

VCI Kraft Packaging Paper is an eco-friendly VCI paper developed using high-quality kraft paper as its base material. It features a plastic-free structural design and a lightweight profile (47–100 g/m²), which helps reduce packaging costs. It is particularly well-suited for meeting the daily corrosion prevention needs of the automotive parts, machinery manufacturing, and metal processing industries. Manufactured using renewable raw materials, VCI paper sheet is both recyclable and biodegradable, fully complying with environmental protection standards.

Product Performance and Structural Advantages:

VCI paper sheet utilizes a double-sided VCI impregnation process, ensuring that the corrosion-inhibiting agents are uniformly distributed throughout the paper's internal structure. Upon packaging, these agents are rapidly released to create a stable protective environment. With a basis weight ranging from 47 to 100 g/m², VCI Kraft Protective Paper achieves material lightweighting while maintaining essential structural strength. VCI Kraft Protective Paper is available in both roll and sheet formats, with a maximum width of up to 2420 mm, enabling it to effectively meet the packaging requirements of products of various dimensions.

Case Study:

A manufacturer of automotive components, exporting steering systems and stamped parts to markets in Southeast Asia and the Middle East, had long grappled with issues of minor oxidation. These problems stemmed from extended transit times (approximately 25–40 days) combined with high environmental humidity (relative humidity ranging from 60% to 85%). Previously, the company utilized standard packaging paper in conjunction with desiccants; however, this approach still presented risks of localized corrosion and the need for rework.

Upon adopting rust prevention paper—a product manufactured by CVCI—the client began using it as an inner packaging material to fully enclose the components, utilizing it in conjunction with sealed outer packaging. Featuring a double-sided VCI-impregnated structure, rust prevention paper continuously releases anti-rust molecules within the enclosed space, thereby significantly reducing quality issues caused by corrosion. The client not only eliminated specific anti-rust processing steps (such as oil application and subsequent cleaning) but also enhanced packaging efficiency and reduced overall costs, resulting in a marked improvement in the stability and reliability of their product deliveries.

Usage Instructions

• Ensure that metal surfaces are clean, dry, and free of contaminants prior to packaging.

• The anti-rust paper must be applied in close contact with the metal surface.

• For regularly shaped items, it is recommended to fully wrap 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 hand perspiration from compromising the anti-rust efficacy.

Specifications and Delivery Capabilities

Rust prevention paper is available in two formats—rolls and sheets—with a choice of brown or white colors. VCI Kraft Packaging Paper's standard basis weight ranges from 47 to 100 g/m², with a maximum width of up to 2420 mm; custom sizes and packaging solutions are available upon request. The standard lead time for orders is approximately 14 days following payment. The MOQ is 300 kg, and the product maintains a shelf life of 3 years under standard storage conditions.

Laboratory and Technical Capabilities:

The company maintains a specialized VCI anti-rust materials laboratory capable of conducting tests on vapor-phase corrosion inhibitor release efficiency, environmental simulation, and long-term anti-rust validation. Through simulations of humid and hot environments, as well as real-world application testing, we ensure that our products provide stable and reliable protection during transit and storage. Furthermore, we offer customized anti-rust solutions tailored to meet the specific application requirements of our clients.
