What is VCI Paper?
VCI, or Vapor Corrosion Inhibitor paper (also referred to as rust inhibitor paper), is a kraft packaging paper manufactured with added VCI chemistry. VCI molecules protect metals from corrosion by forming a thin, invisible layer on the surface.
This layer inhibits the corrosion process caused by oxygen, water, and contaminants. Vapor Corrosion Inhibitor paper can be made in different sizes, weights, and inhibitor types.
It can be ordered in rolls, pre-cut, and with custom printing. Vapor Corrosion Inhibitor paper is typically a kraft material but can be reinforced with a poly layer or scrim-like threads for additional protective properties.
How Does VCI Paper Work?
VCI or Vapor Corrosion Inhibitor paper emits molecules that settle on metal surfaces and form an invisible layer that protects from corrosion. It protects by interrupting the electrochemical corrosion process caused by moisture, oxygen, and contaminants in the atmosphere.
