4x4 StratoGrey Static Shielding Seal Top Bags - Reusable ESD Protection
StratoGrey 4x4 static shielding bags deliver reliable ESD protection for sensitive electronic components through buried metal construction. The reclosable seal top design allows repeated access to contents while maintaining Faraday cage integrity. Semi-transparent material enables quick visual identification without opening, reducing handling time in production and inventory environments.
Specs: 4 x 4" | Static shielding | Reclosable seal top | 3,000/case | Amine-free interior | 3/8" side seal
Applications
These compact 4x4 static shielding bags protect small electronics, integrated circuits, memory modules, and sensitive components from electrostatic discharge during storage and handling. Electronics manufacturers use them for IC chips, processors, and small PCB assemblies. Repair facilities rely on this size for storing replacement parts and customer components awaiting service. Data centers stock them for RAM modules, SSDs, and controller cards. Quality control departments use the translucent material for visual inspection without compromising ESD protection.
Key Features
- Faraday Cage Protection: Buried metal construction creates a complete electromagnetic shield around contents
- Amine-Free Interior: Will not corrode polycarbonate surfaces or cause outgassing that damages sensitive electronics
- Reclosable Seal Top: Provides repeated access for components requiring multiple inspections or staged assembly
- Semi-Transparent Material: Allows content identification without opening, maintaining ESD protection during inventory checks
- 3/8" Side Seal: Ensures packaging integrity during storage, shipping, and repeated handling
Common Questions
Q: What's the difference between static shielding bags and anti-static bags?
A: Static shielding bags like StratoGrey provide Faraday cage protection—they block external static charges from reaching contents. Anti-static bags only prevent static buildup on the bag surface but don't shield contents from external discharge. For sensitive ICs and PCBs, static shielding offers superior protection.
Q: Why does amine-free matter for electronics packaging?
A: Standard packaging materials may contain amines that can corrode polycarbonate components and cause contamination through outgassing. StratoGrey's amine-free interior eliminates this risk, making it safe for disk drives, optical components, and precision electronics.
Q: Can I reuse these bags?
A: Yes. The reclosable seal top is designed for multiple open/close cycles. As long as the bag isn't punctured or torn, it maintains full ESD shielding properties through repeated use.
