Value Brand Static Shielding Bag, Zip Seal, 5 in L, 3 in W, 0.003 in

Static Shielding Bag 5×3 in

These anti-static bags measure 5 inches long by 3 inches wide and use a zip-seal closure for repeated access. They are made from low-density polyethylene with a metalised layer that provides Faraday cage protection for sensitive electronic components. Each bag is 0.003 inches thick and coloured grey.

Build quality and daily use

The material delivers a puncture strength of 2.6 lbf and a seal strength of 28.7 N, so the closure holds firm during handling and transit. Supplied flat-packed in a quantity of 3000, the reclosable design lets technicians open, inspect and reseal without replacing the bag. Note that the product carries California Proposition 65 warnings for cancer and reproductive harm.

Faraday cage protection level

The single specification that decides suitability is the standards-compliant Faraday cage shielding, which blocks external electrostatic fields from reaching the contents. Buyers who need moisture-barrier or vacuum-seal properties should look elsewhere, as this bag only addresses static shielding.
