Static electricity protection: The inner coating makes the surface resistance of the material reach 10^6-10^10Ω, which allows static electricity to be released faster and prevents the accumulation of static electricity charges.
Electromagnetic shielding: The aluminum foil layer reflects/absorbs electromagnetic waves, with a shielding effectiveness of over 60dB.
Physical protection: The nylon layer (NY) enhances the puncture resistance of the film, and the polyethylene layer (CPE) provides stable heat sealing performance and good tensile strength.

ESD Shielding Antistatic Bags for Electronics are specialized packaging solutions designed to protect electrostatic-sensitive devices (ESDs) from damage caused by electrostatic discharge (ESD) and environmental factors. Constructed with multi-layer materials such as VMPET (vacuum metallized polyester) (50-75μm thickness) and PE (polyethylene) (20-30μm thickness), these bags create a Faraday cage effect-a phenomenon where the conductive outer layer redistributes electrostatic charges to neutralize external fields while the inner dissipative layer prevents charge buildup on contents. They are widely used in industries requiring strict ESD control, including semiconductor manufacturing, PCB assembly, and electronics logistics, with adoption rates exceeding 85% in Fortune 500 electronics firms.
Provide surface resistivity of 10⁸-10¹¹ ohms (measured per ANSI/ESD STM11.11), ensuring static charges are safely dissipated at a rate of <0.1 seconds.
Shielding efficiency up to 60 dB (tested at 30 MHz~1 GHz), blocking electromagnetic interference (EMI) and radio frequency interference (RFI) that could disrupt sensitive circuitry.
Four-layer composite structure (static dissipative coating/VMPET/PE/static dissipative coating) offers high puncture resistance (16 lbs force per ASTM D3763) and tear strength (2.5 N/mm per ASTM D1004).
Heat-sealable design (sealing temperature: 120-150°C) ensures airtight closure, with moisture vapor transmission rate (MVTR) <0.1 g/m²/24h to prevent corrosion.
Functional Design:
Semi-transparent VMPET layer allows visual verification of contents without compromising ESD protection, reducing handling time by 30% compared to opaque alternatives.
Available with optional zipper closures for repeated access, suitable for work-in-progress storage.
Compliance:
Meet ANSI/ESD S20.20 and IPC/JEDEC J-STD-033 standards for ESD-safe packaging, with batch-specific test reports available for audit trails.
Semiconductor Industry: Packaging for ICs (integrated circuits), wafers (4-12 inch diameters), and transistors during cleanroom storage and inter-facility transportation.
PCB Manufacturing: Protecting bare and populated PCBs from static damage during assembly, wave soldering, and functional testing.
Consumer Electronics: Safeguarding sensitive components like SSDs (solid-state drives), HDDs (hard disk drives), and motherboards in retail and e-commerce fulfillment.
Aerospace & Defense: Shielding military-grade electronics (radar modules, communication chips) from electrostatic hazards in field deployment and storage.
Q: How do I verify the ESD performance of these bags?
A: The bags undergo rigorous testing for surface resistivity (per STM11.11) and shielding effectiveness (per STM11.31), with certificates including test dates, batch numbers, and compliance metrics available upon request.
Q: Can these bags be used for vacuum packaging?
A: Yes, they are compatible with vacuum-sealing machines (operating pressure: -0.08 to -0.1 MPa) to maintain moisture-free environments, extending component shelf life by 2–3 times.
Q: Are they reusable?
A: While not recommended for critical applications, proper handling (avoiding punctures, cleaning with isopropyl alcohol) allows 2–3 reuses before shielding efficiency degrades below 40 dB.
Q: Do they come in custom sizes?
A: Yes, manufacturers offer tailored dimensions (minimum 50x50mm, maximum 1000x1500mm) to fit specific components, including custom printing (up to 4-color) for branding and part number identification.
