MAIFUDEShielding Bags (Metalized Shielding Bags)
Multi-layer Faraday cage protection — ESD, moisture, and dust barrier in one solution
Shielding Bags
Maximum Protection with Faraday Cage Technology
Our metalized shielding bags feature a multi-layer construction (PET / Metalized PET / LDPE) that creates a Faraday cage effect, providing complete protection against electrostatic discharge (ESD), electromagnetic interference (EMI), moisture, and dust.
Ideal for high-value electronic components that require the highest level of protection during storage and transportation — IC chips, wafers, PCBs, and precision electronic assemblies.
