FAQs
What is the SCS Dri-Shield 2000 Moisture Barrier Bag, and what protection does it provide?
The Dri-Shield 2000 bag uses a multi-layer laminate of aluminized polyester and polyethylene to provide both moisture vapor barrier protection and static shielding. The foil-layer construction acts as a Faraday-style shield, protecting contents from electrostatic discharge (ESD) while blocking moisture and humidity.
What items are best stored inside this barrier bag?
This bag is ideal for storing or transporting moisture-sensitive and ESD-sensitive items, especially electronic components, PCBs, storage media, semiconductors, or assemblies where both static and humidity exposure must be avoided.
Why is a bonded / foil-laminate bag better than standard plastic or anti-static bags for this use case?
Unlike simple anti-static or polypropylene bags, the Dri-Shield 2000 barrier bag offers dual protection: the foil shield provides true ESD shielding (far better than just dissipative or antistatic material), while the laminate construction dramatically lowers moisture-vapor transmission. This reduces the risk of moisture ingress and static discharge during storage or transit.
How should I package components to maximize protection using this bag?
Place the component in the bag, optionally add a desiccant pack and humidity indicator card, then fully seal or zip-top the bag. For long-term or highly moisture-sensitive storage (e.g., moisture-sensitive devices with MSL requirements), vacuum sealing or heat sealing further improves protection.
Are there any limitations or conditions under which this bag should not be used?
Yes, if the bag is punctured, torn, or not properly sealed, the foil barrier protection is compromised. Also, these bags do not replace environmental controls: humidity, temperature, and static control procedures are still critical for sensitive electronics. For long-term storage, desiccants and humidity-indicator cards are recommended.
