EMP‑Rated Nesting Faraday Bags
NEST‑Z Series EMP Nesting Bags
NEST‑Z Series EMP Nesting Bags
The NEST‑Z Series is a range of EMP‑rated, ESD‑safe nesting Faraday bags designed to protect sensitive electronics from damaging electromagnetic effects and electrical currents. Built as a robust, multi‑layer moisture‑barrier style bag, NEST‑Z is ideal for packaging, transport and storage of high‑value electronic equipment where physical durability and EMP-focused protection matter.
Each NEST‑Z bag combines aluminium barrier shield layers with heavy‑gauge static‑dissipating polyester layers to create a static‑safe environment for devices, while helping reduce puncture risk in transit. The bags are also heat‑sealable and suitable for vacuum packing, supporting longer‑term storage and logistics workflows.
Important note: NEST‑Z bags are intended for EMP / HEMP / CME protection. They are not designed to block communications signals such as cellular, GPS, Wi‑Fi or Bluetooth. If you need RF signal isolation for forensics or operational security, speak with J3Seven about purpose-built signal-blocking Faraday bags and enclosures.
Key benefits
- EMP‑focused protection: Designed for EMP/HEMP/CME scenarios and electronics survivability workflows.
- ESD‑safe construction: Static‑dissipating layers help support safe handling of sensitive electronic components.
- Rugged multi‑layer build: Heavy‑gauge layers help reduce puncture risk during storage and transport.
- Heat‑sealable + vacuum pack compatible: Supports long‑term storage, logistics and evidence-style packaging approaches.
- Scalable sizing: Options range from small media/card sizes through to very large equipment bags.

NEST‑Z size options (mm)
NEST‑Z bags are available in multiple sizes and pack quantities (single bags and multi‑packs). Common size options include:
| Use category | Bag size (approx.) | Typical items |
|---|---|---|
| Cards / small media | 64 mm × 102 mm | Cards, USBs, SD/memory media, small accessories |
| Mobile device size | 127 mm × 178 mm | Phones, handheld devices, small electronics |
| Tablet / notebook size | 203 mm × 254 mm | Tablets, compact devices, small assemblies |
| Laptop / equipment size | 305 mm × 457 mm | Laptops, instrumentation modules, packed electronics |
| Large equipment size | 457 mm × 711 mm | Larger devices, boxed electronics, multiple items |
| Extra‑large heat‑seal option | 864 mm × 1,016 mm | Bulky electronics and larger packed equipment |
Typical applications
- Logistics and storage: Packing and transporting sensitive electronics as part of EMP resilience planning.
- Maintenance and spares: Protecting critical electronic spares, boards and modules during long‑term storage.
- Medical and mission‑critical equipment: Protecting high‑value devices where uptime and replacement lead times matter.
- Facilities preparedness: Supporting layered EMP protection strategies alongside other mitigations.
Selection guidance
- Measure the packed item, not just the device: Allow space for cases, cables, foam, labels and vacuum‑pack margins.
- Choose the right workflow: Use zip‑seal for repeat access; apply heat‑seal and vacuum packing where long‑term storage is the priority.
- Need RF signal isolation instead? NEST‑Z is EMP‑focused; for cellular/Wi‑Fi/GPS isolation, select a dedicated signal‑blocking bag or enclosure.
