Moisture Barrier Bag

Protective Shielding

Specialized storage vessel engineered from multi-layer films to prevent the entry of ambient water vapor into moisture sensitive hardware. A moisture barrier bag usually contains a core layer of aluminum or polyester to create a physical block against gas diffusion. This item remains necessary for the safe transport of integrated circuits categorized with high sensitivity levels.

The seal must be vacuum tight to remain effective.

Bag Handling

Manual inspection of the foil-like surface ensures that no pinholes or tears exist that could let in humid factory air. Inside every moisture barrier bag, specific indicators must show that the local relative humidity has stayed below a defined percentage throughout the transit cycle. Once a bag is punctured, its contents are deemed exposed to the surrounding room environment.

Operators use heat sealers to close these bags after internal parts are removed.

Defensive Layering

Packaging engineers specify this item for boards or parts that cannot tolerate common humidity exposure without risking failure during reflow. Unlike simple static bags, the moisture barrier bag provides a quantifiable level of resistance to environmental moisture over months of storage. It reduces the need for expensive component baking before assembly.

Each bag is typically discarded after its contents are consumed.
