12x16 StratoGrey Static Shielding Bags - Faraday Cage ESD Protection
StratoGrey 12x16 static shielding bags deliver professional-grade electrostatic discharge (ESD) protection for sensitive electronic components, circuit boards, and assemblies. The buried metal construction creates a true Faraday cage that shields contents from both tribocharging and external static fields—providing the double protection critical for high-value electronics handling and storage.

Applications
These static shielding bags serve electronics manufacturing, repair, and distribution operations where ESD damage prevention is essential. Circuit board manufacturers use them for work-in-progress and finished PCB storage. Electronics distributors package replacement parts, modules, and sensitive components for safe shipping. Data center operations rely on static shielding for storing spare drives, memory modules, and network cards. Aerospace and defense contractors specify shielding bags for mission-critical avionics components. Medical device manufacturers protect sensitive diagnostic equipment components during assembly and distribution.
Key Features
- Faraday Cage Protection: Buried metal layer creates complete electrostatic shielding—blocks both internal charge generation and external static fields
- Amine/Amide-Free Interior: Safe for polycarbonate lenses, displays, and sensitive plastics that can be damaged by outgassing from standard anti-static materials
- Translucent Material: Semi-transparent construction allows visual identification of contents without opening—critical for inventory management and inspection
- 3/8" Side Seal: Wide heat-sealed edges ensure packaging integrity during storage, handling, and shipping
- Reusable Design: Seal-top closure allows repeated access for components that require multiple handling cycles during assembly or testing
Static Shielding vs. Anti-Static
Static shielding bags like StratoGrey provide superior protection compared to standard pink anti-static bags. While anti-static poly only prevents triboelectric charge generation, static shielding bags actively block external electrostatic fields from reaching the contents. The buried metal layer acts as a Faraday cage—the same principle that protects airplane electronics from lightning strikes. For Class 0 and Class 1 ESD-sensitive devices, shielding bags are the recommended packaging choice per ANSI/ESD S541.
Common Questions
Q: What's the difference between static shielding and anti-static bags?
A: Anti-static bags (pink poly) only reduce surface charge generation. Static shielding bags contain a metal layer that creates a Faraday cage, actively blocking external static fields from reaching contents. For sensitive electronics like PCBs and ICs, shielding bags provide significantly better protection.
Q: Are these bags safe for polycarbonate components?
A: Yes. StratoGrey bags use an amine/amide-free interior that won't cause stress cracking or hazing on polycarbonate surfaces. Standard anti-static treatments can damage PC materials—these bags are specifically formulated to avoid that issue.
Q: Can I reuse these static shielding bags?
A: Yes, the seal-top closure design allows repeated opening and resealing. As long as the bag isn't punctured or torn, the Faraday cage protection remains intact for multiple use cycles.
