StratoGrey Static Shielding Bags 15x20 - Faraday Cage ESD Protection
StratoGrey 15x20 static shielding bags deliver dual-layer ESD protection through buried metal construction, creating a complete Faraday cage around sensitive electronic components. The amine-free interior ensures compatibility with polycarbonate surfaces and sensitive assemblies, eliminating corrosion and outgassing concerns that can compromise delicate electronics during storage and transit.

ESD Protection Applications
The 15x20 size accommodates a wide range of electronic assemblies and components requiring static shielding. PCB manufacturers and electronics assemblers use this size for motherboards, graphics cards, and multi-board assemblies. Data center operations rely on these bags for storing replacement server components and network cards. The generous dimensions fit standard ATX and larger form factor boards with room for anti-static foam inserts when additional cushioning is required.
Repair depots and refurbishment centers stock this size for receiving and shipping sensitive modules. Contract manufacturers use StratoGrey bags throughout the production process—from incoming component storage through finished assembly packaging. The seal-top closure allows repeated access without compromising protection, making these ideal for work-in-progress applications where components must be accessed multiple times.
Key Features
- Faraday Cage Protection: Buried metal layer creates complete electrostatic shielding envelope around contents
- Amine-Free Interior: Will not corrode polycarbonate surfaces or cause outgassing that damages sensitive components
- Translucent Material: Semi-transparent construction allows visual identification of contents without opening
- 3/8" Side Seal: Wide heat-sealed edges ensure packaging integrity during handling and storage
- Seal-Top Closure: Resealable design for multi-access applications in production environments
- LK Packaging Quality: Defect-prevention manufacturing builds reliability into every bag
How Static Shielding Works
Unlike anti-static bags that simply dissipate surface charges, static shielding bags with buried metal construction create an actual Faraday cage. This metal layer completely surrounds the contents, blocking external electrostatic fields from reaching sensitive components. When a charged object contacts the bag exterior, the charge flows around the outer surface without penetrating to the interior—protecting even the most ESD-sensitive devices rated to less than 100 volts.
Common Questions
Q: What's the difference between static shielding and anti-static bags?
A: Anti-static bags prevent triboelectric charge generation but don't block external fields. Static shielding bags with buried metal construction create a Faraday cage that blocks external ESD events from reaching contents—critical for Class 0 and Class 1 ESD-sensitive devices.
Q: Are StratoGrey bags safe for polycarbonate components?
A: Yes. The amine-free and amide-free interior formulation specifically prevents chemical attack on polycarbonate surfaces. No outgassing occurs during storage, making these safe for optical drives, LED assemblies, and other polycarbonate-containing electronics.
Q: Can I see what's inside without opening the bag?
A: Yes. StratoGrey's semi-transparent material allows visual identification of contents through the bag, enabling inventory verification and part number confirmation without breaking the protective seal.
