Anti-static bags vs shielding bags: selection and acceptance guide
Start with device sensitivity and whether the package will leave an electrostatic protected area (EPA). Then check low charging, dissipation or conductivity, and discharge shielding requirements. Colour or a single resistance reading is not enough to select a package.
What do anti-static and shielding properties do?
Swipe the table horizontally to see all columns.
The EOS/ESD Association distinguishes low charging, dissipation or conductivity, and discharge shielding. Its guidance adds discharge shielding for packaging outside an EPA. See the reference below.
| Property to check | Information to request | What not to assume |
|---|---|---|
| Low charging | Contact conditions and test method | Pink colour proves suitability |
| Dissipation or conductivity | Method, conditions, result and units | One resistance value proves all protection |
| Discharge shielding | Package test and closure requirements | A metallic appearance proves shielding |
Keep resistance, resistivity and shielding specifications separate. Ask for results using the method and units defined in your purchasing specification.
How should candidate packages be compared?
Describe the application before choosing the bag. Record exposed components, weight, sharp edges, packing and unpacking environments, shipping route, storage period, cushioning and moisture needs.
- Write an acceptance checklist based on the device or customer specification.
- Request reports for the proposed material and construction; match sample identifiers.
- Trial-pack the actual item and check usable dimensions, closures and sharp edges.
- Test against the agreed plan and retain batch identifiers and results.
Specify ESD protection, cushioning, moisture protection and EMI protection separately. A discharge-shielding report is not evidence of shielding across all electromagnetic frequencies.
What information is needed for a quote?
Provide item photos and dimensions, usable bag dimensions, closure design, electrical requirements and test methods, transport and storage conditions, quantities, artwork and delivery location.
Include an approved sample or customer specification where available. Confirm service life, printing capability, minimum quantity and timing for the specific proposal.

Frequently Asked Questions
01 Can a pink anti-static bag replace a shielding bag?
Colour is not a sufficient basis for substitution. Match the specified properties, including discharge shielding for transport outside an EPA.
02 Is there a universal three-year service life?
This guide makes no universal service-life claim. Confirm shelf life and retesting against material-specific evidence and storage conditions.
03 What should a resistance report include?
Check sample identity, method and edition, environmental and conditioning details, units and test date. Confirm applicability to the proposed material and construction.
