What Are StratoGrey Static Shielding Bags?
StratoGrey™ static shielding bags are specialized ESD (electrostatic discharge) packaging designed to protect sensitive electronic components during storage, handling, and shipping. Unlike standard anti-static bags that only prevent static buildup, static shielding bags actively block external electrostatic fields from reaching the contents inside.
The StratoGrey line features a distinctive semi-transparent grey design with three protective layers:
- Outer static dissipative layer – Prevents triboelectric charging
- Middle conductive metal layer – Creates a Faraday cage effect to shield contents
- Inner static dissipative layer – Safely dissipates any internal static charges
Common Uses for Static Shielding Bags
Electronics manufacturers, repair labs, and assembly facilities rely on StratoGrey bags daily to protect:
- Circuit boards and PCBs (printed circuit boards)
- Computer hard drives (HDD and SSD)
- Memory modules (RAM, flash storage)
- Semiconductors and integrated circuits
- Sensitive sensors and measuring equipment
- Communication devices and components
Why Choose StratoGrey Over Standard Anti-Static Bags?
Standard pink anti-static bags only prevent static buildup inside the bag. They do NOT protect against external electrostatic fields. If someone walks across a carpet wearing synthetic clothing and picks up a pink anti-static bag, that external charge can still damage the electronics inside.
StratoGrey static shielding bags provide complete protection with a conductive metal layer that acts as a Faraday cage, blocking external static charges from penetrating the bag. This makes them essential for:
- High-value electronics (where damage costs exceed bag costs)
- Ultra-sensitive components (military, aerospace, medical devices)
- Environments with high static risk (low humidity, synthetic flooring)
- Shipping and transport (where ESD control is limited)
