Choosing the Right ESD Packaging: Shielding, Static‑Dissipative & Moisture Protection

A practical buyer's guide to selecting the right packaging for sensitive components.

Why Packaging Is One of the Most Overlooked ESD Controls

Most ESD events occur when components leave the workstation — often during transport, staging, kitting, or storage. Packaging is your product's “last line of defense,” yet it's one of the most misunderstood categories in static control.

Different packaging materials behave very differently under charge. Choosing the wrong one can mean the difference between a safe product and latent damage that appears weeks later. For a complete guide to building and maintaining an ESD control program, visit our ESD Program Essentials hub.

Three Major Packaging Categories — and When to Use Each

1. Static‑Dissipative Bags

Useful for non‑ESD sensitive items or items already inside a shielding container. They prevent charge buildup on the bag itself, but do not protect against external discharge.

2. Shielding (Metal‑In/Metal‑Out) Bags

The standard for transporting and storing electronics. Shielding bags create a Faraday cage that protects components from external ESD events.

Desco Shielding Bags

3. Moisture Barrier Bags (MBB)

Critical for PCBs, BGAs, and moisture‑sensitive components. These bags prevent moisture ingress during storage and reflow prep.

Don't Forget Labels, Humidity Cards & Desiccants

ESD and MSL packaging is a system, not a single SKU. Combine bags with:

• MSL & ESD Warning Labels
• Desiccant Packs
• Humidity Indicator Cards (HICs) for reflow readiness
