Shielding bags use a multi-layer metallised laminate for ESD protection of static-sensitive devices during handling, storage and shipment.
- Metallised laminate structure provides electrostatic shielding
- Material and bag style selected for the device, environment and acceptance needs
- Custom size and closure available
- For protection of circuit boards, modules and sensitive components
Shielding values and test data are confirmed against device requirements.

Frequently Asked Questions
01 How do anti-static, conductive, and shielding bags differ?
Low charging, conductivity or dissipation, and discharge shielding address different risks. A multilayer bag may provide several of these properties; confirm them with the appropriate tests.
02 Is a lower-resistance conductive bag always better?
No. Resistance is one part of the specification. Select it together with charging, shielding and the device manufacturer’s handling requirements.
03 Is the 10³–10¹¹ Ω range on the anti-static bubble bag a single SKU?
No. Spanning 8 decades physically requires different material systems. Aspirature lists the broad range in the manual; the specific tier is confirmed per customer before quoting.
04 Why combine shielding with anti-static?
Low-charging surfaces limit charge generation during contact, while a suitable shielding structure protects against external discharge. A complete package may need both.
