4x6 StratoGrey Static Shielding Reclosable Bags - ESD Protection for Sensitive Electronics
The SSR0406 StratoGrey static shielding bag by LK Packaging delivers professional-grade electrostatic discharge protection for sensitive electronic components. These 4x6 reclosable bags feature buried metal construction that creates a true Faraday cage, blocking both static fields and direct discharge. The seal-top closure allows repeated access without compromising protection—ideal for components that require testing, inspection, or multi-step assembly processes.
Specs: 4 x 6" | Buried metal static shielding | Reclosable seal top | 3,000/case | Amine-free interior | 3/8" side seal
Commercial Applications
Electronics manufacturers rely on StratoGrey static shielding bags for protecting integrated circuits, memory modules, and sensitive PCB assemblies during storage and transport. Contract assembly operations use the reclosable feature for work-in-progress components that move between stations. Quality control departments appreciate the semi-transparent material that allows visual inspection without opening the bag. Data centers and IT departments stock these bags for protecting replacement drives, memory, and network cards. Repair shops and refurbishment operations use them for organizing and protecting customer components throughout the service process.
Key Features
- Faraday Cage Protection: Buried metal construction provides complete shielding against electrostatic fields and discharge events
- Amine/Amide-Free Interior: Safe for polycarbonate surfaces—will not cause stress cracking or corrosion on sensitive plastics
- No Outgassing: Clean interior chemistry prevents contamination in controlled environments and cleanroom applications
- Reclosable Seal Top: Press-to-close zipper allows repeated access while maintaining protection integrity
- Semi-Transparent Material: Easy identification of contents without opening—reduces handling and exposure
- 3/8" Side Seal: Wide seal ensures packaging integrity during storage, shipping, and handling
Understanding Static Shielding vs. Anti-Static
Static shielding bags like the StratoGrey provide superior protection compared to standard anti-static (pink) bags. While anti-static bags only prevent static generation from the bag material itself, static shielding bags create a Faraday cage that blocks external electrostatic fields from reaching the contents. This makes shielding bags essential for highly sensitive components like CPUs, memory chips, and precision electronics where even nearby static discharge could cause damage.
Common Questions
Q: What's the difference between static shielding and anti-static bags?
A: Anti-static (pink) bags only prevent the bag from generating static. Static shielding bags like StratoGrey have buried metal that creates a Faraday cage, blocking external static fields from reaching contents. For sensitive ICs and PCBs, shielding bags provide significantly better protection.
Q: Are these bags safe for polycarbonate components?
A: Yes. StratoGrey bags use an amine-free and amide-free interior formulation specifically designed to prevent stress cracking and corrosion on polycarbonate surfaces—a common concern with some ESD packaging materials.
Q: Can I reuse these bags?
A: The reclosable seal top is designed for multiple open/close cycles. For maximum protection, inspect bags for tears or punctures before reuse and ensure the seal engages fully. Replace bags showing wear or damage to the metallic shielding layer.
