VCI devices add an important dimension to corrosion preventive packaging.
Devices that give off, or emit, VCI compounds protect recessed areas within a package. VCI devices can be inserted in hard to reach areas. Often, they are used simply to enhance protection by giving a ‘boost’ of available VCI.
In some cases, a VCI pouch or chip can be added to a plain poly bag to provide VCI protection where none existed before.
