Q. How does corrugated cardboard affect corrosion?
Corrugated cardboard is generally acidic by nature and acts as a sponge & absorbs moisture due to its characteristics. Corrugated cardboard Absorbs  Moisture within a normal distribution environment. When Metal or Metal parts are placed directly on or near Corrugated Cardboard Moisture and/or Acidity transfer occurs, which will directly cause Corrosion on a Metal Surface.

 Therefore, it is important to place BENZ Packaging Volatile Corrosion Inhibitors between Metals and Acidic and Hygroscopic materials such as Corrugated Cardboard and Wood to prevent Corrosion at contact points.
