ESD Beutel
ESD shielding bags provide a surface resistance of 10¹ to 10⁷ Ω and a shielding attenuation of <20 nJ per IEC 61340-5-1 and ANSI/ESD S11.31, forming a complete Faraday-cage barrier against electrostatic discharge events exceeding 1,000 V HBM. The metalized multi-layer film construction - typically PET/aluminium/PE - combines a low-charging outer surface with a conductive shielding interlayer and a clean-room-compatible inner surface, keeping sensitive components safe from both triboelectric charging and external ESD threats simultaneously.
As a specialist distributor for ESD packaging, esd.equipment stocks 123 shielding bag variants across seal types (heat-seal, zip-lock, self-seal), sizes from 50×75 mm to 400×600 mm, and certified formats compliant with IEC 61340-5-1, DIN EN 61340-5-2, and MIL-PRF-81705D - covering every EPA storage and transport requirement from bare-die shipment to finished PCB dispatch.
