StratoGrey Static Shielding Bags 5x7 - Reclosable ESD Protection by LK Packaging
StratoGrey 5x7 static shielding bags deliver premium ESD protection for sensitive electronic components. The buried metal construction creates a complete Faraday cage that shields contents from both electrostatic discharge and electromagnetic interference. The reclosable seal top allows repeated access while maintaining protection integrity—ideal for production environments where components must be accessed multiple times during assembly or testing.

Applications
These StratoGrey bags serve critical ESD protection needs across electronics manufacturing, assembly, and repair operations. Circuit board manufacturers use them for protecting populated PCBs during storage and inter-facility transport. Electronics assembly lines rely on the reclosable feature for staging sensitive components that require multiple handling steps. Field service technicians use them to protect replacement parts and recovered components. The 5x7 size accommodates small circuit boards, memory modules, integrated circuits, voltage regulators, and similar electronic components requiring serious static protection.
Key Features
- Faraday Cage Protection: Buried metal layer provides complete electrostatic shielding from external discharge events
- Amine-Free Interior: Will not corrode polycarbonate surfaces or produce outgassing that could damage sensitive components
- Semi-Transparent Material: Easy visual identification of contents without opening the bag
- Reclosable Seal Top: Zipper-style closure allows repeated access while maintaining ESD protection
- 3/8" Side Seal: Wide heat-sealed edges ensure packaging integrity during storage and handling
Static Protection Standards
StratoGrey bags meet ANSI/ESD S541 requirements for ESD protective packaging. The buried metal construction provides superior shielding compared to standard metallized bags, making them suitable for highly sensitive semiconductor devices, precision instruments, and mission-critical electronics. The double-protection design guards against both triboelectric charging and direct discharge events.
Common Questions
Q: What's the difference between static shielding bags and anti-static bags?
A: Static shielding bags like StratoGrey have a metal layer that creates a Faraday cage, blocking external ESD from reaching contents. Anti-static bags only prevent charge generation from the bag itself—they don't shield against external discharge. For sensitive electronics, shielding bags provide far superior protection.
Q: Are these bags safe for polycarbonate components?
A: Yes. StratoGrey's amine-free interior specifically addresses polycarbonate compatibility. Standard ESD bags containing amines can cause stress cracking in polycarbonate—StratoGrey eliminates this risk.
Q: Can I reuse these bags?
A: The reclosable seal top is designed for multiple open-close cycles. For continued ESD protection, inspect bags for punctures, tears, or wear before reuse. Replace bags showing visible damage to the metal layer.
