Complete Guide for PCB & Electronics Packaging
Static shielding bags are specialized ESD packaging materials designed to protect sensitive electronic components from electrostatic discharge (ESD) by blocking external static charges.
They are commonly used for:
PCB boards
Integrated circuits (ICs)
Semiconductor components
Electronics during shipping and storage
Unlike pink anti static bags, shielding bags provide true Faraday cage protection.

| Feature | Static Shielding Bags | Anti Static Bags (Pink) |
|---|---|---|
| ESD Protection | ✔ Blocks external static | ✘ Only reduces static generation |
| Faraday Cage Effect | ✔ Yes | ✘ No |
| Material | Multi-layer with metal shielding | Polyethylene with additives |
| Use Case | PCB / IC / sensitive electronics | General packaging |
| Color | Silver / Metallic | Pink |
Static shielding bags are multi-layer protective packaging materials engineered to prevent electrostatic discharge from damaging sensitive electronics.
They are typically made of:
Outer dissipative layer
Polyester layer
Metal shielding layer
Inner polyethylene layer
These layers work together to block static charges from entering the bag.

Static shielding bags function using the Faraday cage principle.
When external static electricity comes into contact with the bag:
Charges distribute across the outer surface
The inner contents remain protected
No static reaches the electronic components
This is critical in environments where even small electrostatic discharge can damage ICs or PCBs.
A typical shielding bag includes:
Outer Layer (Dissipative): prevents static buildup
Polyester Layer: adds strength and durability
Metalized Layer: blocks electrostatic fields
Inner Layer: safe contact surface
This structure is why shielding bags are used in electronics manufacturing and export packaging.

Static shielding bags are essential because:
PCBs are highly sensitive to ESD
ICs can fail from invisible damage
Static can reduce product lifespan
Industries that rely on them:
Electronics manufacturing
PCB assembly
Semiconductor production
Export logistics
Static shielding bags and anti static bags are often confused, but they serve different purposes.

Many buyers assume pink anti static bags provide full protection.
👉 This is incorrect.
They only reduce static generation — they do NOT block external ESD.
For sensitive electronics, always use static shielding bags.
Shielding bags block external electrostatic discharge, while anti static bags only reduce static buildup and do not provide full protection.
Yes, as long as they are not physically damaged or contaminated.
No. For PCB and IC packaging, shielding bags are strongly recommended.
3 mil is the most commonly used thickness for electronics packaging.
We supply high-quality ESD packaging for electronics manufacturing and export.
