Static Shielding Bags for Electronics, Zip, Open-Top

Static Shielding Bags

Static shielding bags are specialized packaging designed to protect electronic components from electrostatic discharge (ESD) and electromagnetic interference during storage or transportation. These bags are widely used in semiconductor manufacturing, PCB assembly, aerospace electronics, and precision instruments.

Unlike regular plastic packaging, static shielding bags feature a multi-layer construction with a metalized shielding layer, creating a Faraday cage effect to block external static charges and maintain product integrity.

Key Features

Multi-Layer ESD Protection
– PET outer layer for durability
– Metalized layer for EMI shielding
– Inner static dissipative polyethylene for safe contact

High ESD Performance
– Surface resistance: 10⁶ – 10¹¹ Ω/sq
– Shielding effectiveness: ≥30 dB against EMI

Transparency for Easy Identification
– Semi-transparent design for barcode scanning and visual checks

Customizable Options
– Sizes: small IC to large PCB packaging
– Open-top, zip-lock, heat-sealed versions

Compliance
– ANSI/ESD S541, IEC 61340-5-1, RoHS compliant
