In the rust-proof packaging industry, there's a vast array of rust-proof paper products, with many inferior ones being passed off as genuine. Many customers struggle to choose the right alloy rust-proof paper packaging due to a lack of knowledge, resulting in unresolved rust protection issues for metal products.

The VCI Corrosion Inhibiting Paper is made by refining rust-preventing base paper with a compounded VCI (Volatile Corrosion Inhibitor) liquid through special processing techniques. Among the various materials in the packaging industry, VCI paper is a high-tech product, with its core technology lying in the VCI aspect. VCI technology is an integrated field that encompasses organic synthesis, physical chemistry, corrosion and protection, metal materials, paper processing, and polymer technologies. Within the sealed packaging space, the VCI within the paper begins to sublimate and emit corrosion-inhibiting gas factors at room temperature and pressure, diffusing and permeating to the surface of the protected items and adhering to them, forming a dense protective film layer with a monomolecular thickness, thereby achieving the purpose of rust prevention.

"Yongyu" brand VCI rust-preventive paper is suitable for various metal materials and products, including iron, alloy steel, cast iron, copper, brass, bronze, electroplated metals, zinc and alloys, chromium and alloys, cadmium and alloys, nickel and alloys, tin and alloys, and aluminum and alloys.
