StratoGrey Static Shielding Bags 4x4 - ESD Protection for Sensitive Components
StratoGrey 4x4 static shielding bags by LK Packaging deliver professional-grade ESD protection for small electronic components, integrated circuits, and static-sensitive assemblies. The buried metal construction creates a true Faraday cage that shields contents from electrostatic discharge during handling, shipping, and storage. Ideal for electronics manufacturing, repair facilities, and component distribution operations.
Specs: 4 x 4" | Buried metal construction | Semi-transparent | 3/8" side seal | 1,000/case | Amine-free interior
ESD Protection Applications
The 4x4 size accommodates a wide range of static-sensitive components commonly handled in electronics operations. Circuit boards up to 3.5x3.5" fit with clearance for heat sealing. Small IC chips, memory modules, microprocessors, and surface-mount components all benefit from the Faraday cage shielding. Repair technicians use these bags for storing customer components awaiting service. Quality control departments rely on them for sample retention and failure analysis storage. The compact footprint makes them efficient for small parts bins and component drawers in production environments.
Key Features
- Buried Metal Faraday Cage: Internal metal layer provides complete shielding from external static fields and discharge events
- Amine/Amide-Free Interior: Safe for polycarbonate surfaces with no corrosion risk or outgassing concerns
- Semi-Transparent Material: Easy visual identification of contents without opening the sealed bag
- 3/8" Side Seal: Wide seal ensures packaging integrity during storage and repeated handling
- Seal Top Closure: Convenient access for components that require multiple inspections or testing cycles
- Quality-Built Construction: Elkay/LK Packaging defect prevention manufacturing for consistent protection
Technical Specifications
StratoGrey bags meet industry standards for static shielding performance. The multi-layer construction combines an outer static-dissipative layer, buried metal shielding layer, and amine-free inner layer that contacts sensitive components directly. This design provides both charge dissipation on the exterior and electromagnetic shielding throughout the bag structure. Surface resistivity and shielding effectiveness meet ANSI/ESD S541 requirements for static protective packaging.
Common Questions
Q: What size components fit in a 4x4 static shielding bag?
A: Interior usable dimensions are approximately 3.5x3.5" accounting for the side seal. This accommodates most DIP packages, small PCBs, IC chips, memory modules, and similar components.
Q: Are StratoGrey bags safe for polycarbonate parts?
A: Yes. The amine-free interior produces no outgassing and will not cause environmental stress cracking or corrosion on polycarbonate surfaces. Safe for optical components and lenses.
Q: Can these bags be resealed after opening?
A: The seal-top design allows repeated access. For permanent closure, use a heat sealer or impulse sealer above the contents. Bags can be trimmed and resealed multiple times during component handling.
