Static Shielding Reclosable Bags in 15" x 18" at 3 mil provide total Faraday cage protection for highly sensitive electronic components including hard drives, SSDs, large circuit boards, and industrial automation assemblies. Three-layer buried metal-in construction shields against electrostatic charges from both inside and outside the bag — the critical distinction from standard anti-static packaging, which only dissipates surface charges.
Specs: 15" x 18" | 3 mil | Static Shielding (Faraday Cage) | Reclosable Zip Top | 50% Transparent | 100/Box | Amine-Free | Polycarbonate Safe
Applications
- Hard drive (HDD/SSD) storage and shipment in compliance-sensitive operations
- Large PCB and circuit board packaging for OEM, defense, and industrial electronics
- Field-replaceable unit (FRU) and spare parts kitting for IT and telecom equipment
- Mil-spec and aerospace electronic component packaging requiring full shielding compliance
Features
- Full Faraday cage protection — shields against static charges from both inside and outside
- Three-layer buried metal-in construction: conductive aluminum shield between two static dissipative polymer layers
- 50% transparent film for product identification without opening the bag
- Reclosable zip top for repeated access in kitting, inspection, and reuse applications
- Contains no amines, amides, or N-Octanoic acid — safe for polycarbonate components
- Yellow static shielding warning label stamped on each bag
Compliance & Standards
Meets the electrical and physical requirements of ANSI/ESD S541 and EIA 625. ANSI/ESD S20.20 program compliant. Tested per MIL-STD-3010 Method 4046 and ANSI/ESD STM11.11. This compliance profile qualifies these bags for use in ISO-certified electronics manufacturing, defense procurement specifications, and telecom OEM packaging programs.
Material Notes
The buried metal-in construction places a conductive aluminum layer between two static dissipative polymer layers. This architecture creates a Faraday cage effect — any external electrostatic field is intercepted and dissipated by the outer polymer layer before reaching the aluminum, and any charge generated inside is contained and dissipated before it reaches the contents. At 3 mil, the bag provides durable handling across multiple open/close cycles without compromising the shield layer integrity.
Use Case Notes
The 15" x 18" format accommodates standard 3.5" and 2.5" hard drives with foam inserts, full-size add-in cards, large industrial PCBs, and rack-mount electronic subassemblies. The reclosable zip top is particularly valued in RMA, repair depot, and field service operations where the same bag may be opened and resealed multiple times during the inspection and return process. Packed 100 per box for production and kitting environments.
Common Questions
Q: What is the difference between static shielding and anti-static bags?
A: Anti-static bags (pink poly) dissipate surface charges to prevent charge buildup on the bag itself. Static shielding bags provide Faraday cage protection — blocking external electrostatic fields from reaching the contents. For sensitive components like HDDs, CPUs, and circuit boards, static shielding is the required specification.
Q: Are these bags reusable?
A: Yes. The reclosable zip top allows multiple open/close cycles. However, the shield integrity should be inspected if the bag is visibly punctured or the metal layer is compromised.
Q: Are these safe for polycarbonate components?
A: Yes. These bags contain no amines, amides, or N-Octanoic acid, making them safe for polycarbonate housings, connectors, and optical components.
Why Buy
A 15" x 18" static shielding bag that meets the full compliance stack — ANSI/ESD S541, EIA 625, ANSI/ESD S20.20, and MIL-STD-3010. Faraday cage protection, reclosable zip top, polycarbonate-safe chemistry, and 50% transparency for visual inspection make this the appropriate choice for HDD packaging, defense electronics, and field service kitting operations where static shielding is a hard requirement, not a preference.
