Learn VCI Rust Prevention Bags: Principles and Features

VCI rust prevention bags are an important solution for rust prevention and protection of metal products, widely used in industrial fields such as automobiles, machinery, electronics, aviation, railways, and wind power. The following is a detailed introduction to the rust prevention principle of VCI rust prevention bags and the difference between them and ordinary plastic bags.

Why can VCI rust prevention bags prevent rust?

VCI rust prevention bags use advanced VCI vapor phase rust prevention technology. When metal products are packaged with VCI+ rust prevention bags, the amount of rust prevention particles released by VCI can be automatically adjusted according to changes in the ambient temperature. When the temperature rises, the diffusion amount of rust prevention particles increases, providing stronger protection; when the temperature drops, the diffusion amount decreases, maintaining an appropriate rust prevention concentration. This automatic adjustment feature makes VCI rust prevention bags more intelligent and efficient. This technology is widely used in the fields of steelmaking, machinery manufacturing, etc., to protect the quality and extend the service life of metal products.

The difference between VCI rust prevention bags and ordinary plastic bags

1.VCI rust prevention bags use special materials and processes to combine VCI vapor phase rust prevention technology with packaging materials to form a protective layer, thereby preventing metal products from rusting and corroding. Ordinary plastic bags do not have this function.

2.VCI rust prevention bags have strong air tightness and moisture resistance, which can effectively prevent the erosion of oxygen, water vapor, and acidic substances, thus achieving the effect of rust prevention and corrosion prevention. The air tightness and moisture resistance of ordinary plastic bags are poor and cannot provide rust prevention protection for metal products. Therefore, rust prevention bags are chosen over ordinary plastic bags for packaging automotive parts, machinery components, precision instruments, military materials, etc.

3. VCI rust prevention bags use environmentally friendly materials and processes in the manufacturing process and do not cause pollution to the environment. They can be recycled and have better environmental friendliness.
