How does moisture in a package affect CAPRUST VCI protection?
A. Packaging films for industrial applications are produced from low and high density polyethylene resins and therefore are resistant to moisture to some degree but not completely. Atmospheric moisture will eventually find its way into a film bag. The presence of moisture in a bag can be expected on surface shipments, particularly shipments crossing the equator. CAPRUST films will inhibit moisture entering a bag provided that the moisture enters the interior of the bag through the film. Corrosion problems arise when moisture is allowed to enter a CAPRUST bag unimpeded by the film, e.g. through an incorrect closure or a significant hole in the bag. An unimpeded air flow into the bag is what must absolutely be avoided.
