Static shielding bags go beyond antistatic — the metalized multi-layer construction creates a Faraday cage that blocks external electrostatic fields from reaching sensitive electronics inside. Pink antistatic bags dissipate charge on contact, but static shielding bags prevent charge from penetrating the bag wall entirely. Choose layflat for one-time packaging or reclosable for components that need repeated access during bench work, test, and storage. All bags 3 mil, packed 100 per case.
