Vapor Barrier Packaging Solutions San Diego

vapor barrier packaging

Electronics and items with sensitive or bare metal surfaces that are being transported by ocean container require moisture vapor proof packaging. Salt water and salt water vapor put sensitive electronic components and metal surfaces at risk of corrosion, potentially harming the product's functionality. Craters & Freighters places items such as these in a moisture vapor barrier bag with activated desiccant inside before heat-sealing the seams. A vacuum is then used to reduce the air volume inside the bag before the final seal, thus lowering the humidity levels inside the barrier bag.

The common barrier material (among many) used by the Government is MIL-PRF-131. The desiccant used is activated clay conforming to the specification MIL-D-3464. A humidity indicator card can be placed inside the barrier bag so that the condition of the item and the desiccant can be checked upon opening. Humidity indicator plugs that project through the barrier material are also available and allow for checking the humidity inside the barrier bag without actually opening it.

The use of moisture vapor barriers and desiccant are currently known in the MIL-STD-2073 specification, under the Method of Preservation, by the codes 50, 51, 52, 53, 54, and 55. This type of packaging helps prevent corrosion of the packed item being by reducing the moisture vapor inside of the heat sealed barrier bag enclosure.
