12x26 StratoGrey Static Shielding Bags - ESD Protection for Large Electronics
LK Packaging's StratoGrey 12x26 static shielding bags provide military-grade electrostatic discharge protection for large circuit boards, server components, and sensitive electronic assemblies. The buried metal construction creates a true Faraday cage that shields contents from both electrostatic fields and direct discharge events—delivering superior protection compared to standard anti-static bags.

Commercial Applications
The 12x26 format accommodates larger ESD-sensitive components common in server manufacturing, telecommunications equipment, and industrial control systems. Electronics manufacturers use these bags for PCB assemblies up to 11x25 inches, including motherboards, backplanes, and multi-slot card cages. Data center operations rely on this size for server blade packaging, network switches, and storage controller boards. Contract electronics manufacturers (CEMs) specify StratoGrey bags for customer shipments where component integrity is critical. The translucent material allows barcode scanning and visual identification without opening the package—essential for inventory control in high-volume operations.
Superior ESD Protection
Unlike basic pink anti-static bags that only prevent triboelectric charge generation, StratoGrey static shielding bags provide true Faraday cage protection. The buried metal layer blocks external electric fields and safely dissipates any discharge that contacts the bag exterior. This dual-protection approach meets or exceeds ANSI/ESD S541 packaging requirements for ESD-sensitive devices. The amine-free and amide-free interior will not corrode polycarbonate surfaces or produce outgassing that could damage sensitive optics, connectors, or coating processes.
Key Features
- Faraday Cage Protection: Buried metal construction shields against static fields and direct discharge
- Amine/Amide-Free Interior: Safe for polycarbonate, optics, and components sensitive to chemical outgassing
- Translucent Material: Easy visual identification and barcode scanning without opening
- 3/8" Side Seals: Strong seals maintain package integrity during handling and storage
- Resealable Design: Open-top allows repeated access for components requiring multiple handling cycles
- No Outgassing: Clean interior chemistry won't contaminate sensitive assemblies
Common Questions
Q: What's the difference between static shielding bags and pink anti-static bags?
A: Pink anti-static bags only prevent charge buildup on the bag itself. Static shielding bags like StratoGrey have a metal layer that creates a Faraday cage, actively blocking external static fields from reaching contents. For high-value or highly sensitive components, shielding bags provide significantly better protection.
Q: What size PCB or component fits in a 12x26 bag?
A: Allow 0.5" clearance on all sides for comfortable insertion. A 12x26 bag accommodates boards or assemblies up to approximately 11x25 inches. For components requiring cushioning, reduce effective size by the thickness of your foam or bubble wrap.
Q: Are these bags safe for cleanroom or optical components?
A: Yes. The amine-free and amide-free interior produces no corrosive outgassing, making StratoGrey bags suitable for polycarbonate lenses, optical assemblies, and cleanroom-sensitive components where chemical contamination must be avoided.
