VCI Bags for Metal Anti-corrosion Packaging

VCI Bags for Metal Anti-corrosion Packaging

What is VCI Technology

VCI is the generic term for “volatile corrosion inhibitor,” “vapor corrosion inhibitor,” or “Vapor phase Corrosion Inhibitor,” a revolutionary technology that simplifies corrosion protection and is ideal for keeping enclosed void spaces (e.g., packages, equipment internals, or structural metal cavities) rust-free.  

What is VCI Film

VCI films and bags contain proprietary blend of Vapor phase Corrosion Inhibitors to protect packaged metals from becoming rusty or corroded.

How Do VCI Films Work

VCI films protect metals both through direct contact and vapor-phase action. In places where the VCI plastic is in direct contact with the metal, VCI molecules adsorb, or temporarily “stick,” on the metal surfaces, creating an invisible molecular barrier against corrosive elements such as oxygen, moisture, and chlorides. As VCI molecules vaporize out of the film and diffuse throughout the package, they also form a protective molecular layer on metal surfaces not in direct contact with the film. When the packaging is removed, the VCI molecules simply vaporize and float away. No extra cleaning or coating removal is needed, and the metal part can be used immediately.

Using method

Before packaging, ensure that the surface of the object to be rustproof is dry and clean, and seal the object to be rustproof at room temperature;
2. Wear gloves when packaging to prevent bare hands from directly touching the objects to be rust-proof;
3. If the packaged object has edges and corners, pay attention not to pierce the gas phase rust bag.

Storage way

1. The product should be stored in a dry, cool and sealed place to avoid damage to the original packaging;
2, according to the requirements of the operation, rust period can be more than 2 years.
