3" X 5" Static Shielding Reclosable Bags 100/Box
Memory Module & IC Chip Static Shielding Bags — 3" x 5" 3 mil
3 mil reclosable static shielding bags sized 3" x 5" with total Faraday cage protection for highly sensitive electronic components. Three-layer buried-metal construction with a conductive aluminum shield layer sandwiched between static dissipative polymeric outer layers provides protection against static charges from both inside and outside the bag. Reclosable zip top with 50% transparency for component identification without opening.

Material Notes
Buried-metal construction places a thin conductive aluminum layer between two static dissipative polymeric plastic layers. This architecture provides Faraday cage shielding (blocking both electrostatic fields and electromagnetic discharge from outside), while the outer static dissipative layers prevent triboelectric charge buildup during handling. Amine, amide, and N-Octanic acid-free formulation ensures compatibility with polycarbonate housings and connector materials.
Use Case Notes
3" x 5" is the standard size for individual memory modules (DDR DIMM sticks), small PCBs, IC chips in tray packaging, and discrete components. The reclosable zip top makes these appropriate for field service kits, warranty replacement parts, and component kits that require repeated opening. ANSI/ESD S541, EIA 625, and ANSI/ESD S20.20 compliance satisfies qualification requirements for electronics contract manufacturing, defense electronics, and medical device assembly environments.
Common Questions
Q: What is the difference between static shielding bags and pink antistatic bags?
A: Static shielding bags provide full Faraday cage protection — blocking electrostatic discharge from both inside and outside the bag. Pink antistatic bags only dissipate surface charge and do not block external electrostatic fields. Use shielding bags when complete ESD protection is required per ESD standards.
Q: Are these bags suitable for long-term storage?
A: Yes. Reclosable static shielding bags with buried metal construction are appropriate for both short-term transit and longer-term storage of ESD-sensitive components when properly sealed.
Q: Can these be resealed and reused?
A: Yes. The reclosable zip top allows multiple open-close cycles. Inspect bags for tears or punctures before reuse, as damage to the metal layer compromises Faraday cage integrity.
Why Buy
100 per box, Faraday cage buried-metal construction, reclosable zip top, and multi-standard ESD compliance (ANSI/ESD S541, EIA 625, ANSI/ESD S20.20) make these the correct specification for electronics assembly, contract manufacturing, and field service operations handling memory modules, ICs, and other highly sensitive components.
