Flat StratoGrey™ Static Shielding Bags

Superior ESD Protection for Sensitive Electronics

StratoGrey™ Flat Static Shielding Bags deliver military-grade protection against electrostatic discharge (ESD) and environmental contaminants. Ideal for electronics manufacturing, repair shops, and warehouse storage.

Key Benefits:

• Buried Metal Layer – Shields components from static charges and electromagnetic interference
• Amine/Amide-Free Interior – Won't corrode polycarbonate or damage sensitive circuits
• Moisture & Dust Barrier – Protects against humidity and particulate contamination
• Semi-Transparent – Easy product identification without opening

Applications: PCBs, semiconductors, hard drives, sensors, RFID components, and other static-sensitive electronics.

Why Choose StratoGrey Static Shielding Bags?

When standard anti-static bags aren't enough, StratoGrey flat static shielding bags provide the highest level of ESD protection available. These bags combine three layers of protection: an anti-static outer layer, a conductive middle layer (buried metal), and a static-dissipative inner layer.

What Makes StratoGrey Different?

Buried Metal Construction: Unlike pink poly anti-static bags that only prevent tribocharging, StratoGrey bags create a Faraday cage effect that blocks external electrostatic fields. This makes them essential for Class 0 and Class 1 ESD-sensitive devices.

Amine-Free Formulation: Many static shielding bags use amine-based additives that can corrode polycarbonate surfaces over time. StratoGrey's advanced formula eliminates this risk, making them safe for optical components, lenses, and sensitive electronic displays.

Zero Outgassing: Critical for cleanroom environments and long-term storage, these bags produce no volatile organic compounds (VOCs) that could contaminate sensitive electronics or optics.

Common Applications

• Electronics Manufacturing: PCB assembly, component storage, work-in-progress protection
• Repair & Service: Hard drive replacement, smartphone repair, computer component handling
• Warehouse Storage: Long-term inventory protection for CMOS chips, sensors, and modules
• Shipping: Safe transport of static-sensitive devices to customers or service centers

How to Choose the Right Size

Select a bag that allows 1-2 inches of clearance around your component on all sides. This prevents stress on pins and connectors while ensuring a proper seal. For irregular shapes, use the next size up to avoid punctures.

Static Shielding Bags vs. Anti-Static Bags

Pink Poly Anti-Static Bags: Prevent tribocharging (friction-generated static). Good for Class 2-3 devices. Lower cost.

StratoGrey Shielding Bags: Block external ESD and electromagnetic interference. Required for Class 0-1 devices. Higher protection.

If you're unsure which type you need, check your component's ESD sensitivity rating or consult the manufacturer's packaging specifications.

Compliance & Standards

StratoGrey bags meet or exceed industry standards for ESD protection, including ANSI/ESD S20.20 and relevant MIL-SPEC requirements. They are manufactured in ISO-certified facilities with lot traceability.
