Aluminum Foil Antistatic Bags for PCB are specialized packaging solutions designed to protect printed circuit boards from ESD, moisture, and physical damage. Their laminated structure (PET/aluminum foil/PE) combines aluminum foil (9–12μm thickness) for shielding and static-dissipative polymers for charge dissipation, using advanced dry-lamination technology to ensure layer adhesion >3 N/15mm. These bags are widely used in PCB manufacturing, electronics assembly, and logistics, with a 65% adoption rate in mid-sized electronics firms.
Aluminum foil layer provides 45 dB EMI attenuation (30 MHz–1 GHz), blocking external electrostatic fields and reducing ESD-related defects by 50% in PCB assembly.
Surface resistivity of 10⁸–10¹¹ ohms (per STM11.11) ensures safe charge dissipation, with inner layer resistance stable across 30–60% RH.
Low MVTR (<0.1 g/m²/24h) prevents corrosion and oxidation, ideal for long-term storage (6–12 months) of PCBs with exposed copper traces.
Oxygen transmission rate <5 cm³/m²/24h minimizes solder joint oxidation in humid climates (≥80% RH).
Puncture resistance of 16 lbs (ASTM D3763) and tensile strength of 3,800 psi (ASTM D882) withstand rough handling in warehouse and shipping environments.
PE inner layer offers chemical resistance to fluxes and cleaning agents commonly used in PCB manufacturing.
Secure closure via heat sealing (130–160°C) or zipper, maintaining airtight conditions with leak rate <1 cm³/min at 1 kPa pressure differential.
Layer | Material | Function |
outer coating | Antistatic polymer materials | Dissipate static electricity |
Outer Layer | PET | Patterns or instructions can be printed on the surface to enhance physical strength and effectively isolate air |
Middle Layer | AL | Effective electromagnetic shielding, and can block the penetration of light, gas, and moisture |
Barrier layer | NY (optional) | Improve puncture resistance, suitable for products to prevent oxidation and vacuum packaging |
Inner Layer | CPE | Can be used for heat sealing bag making, with good tensile strength |
inner coating | Antistatic polymer materials | Dissipate static electricity |
PCB Manufacturing: Protecting boards during soldering (reflow, wave), washing (aqueous, solvent-based), and functional testing (ICT, FCT).
Semiconductor Storage: Packaging ICs, resistors, and capacitors in dry cabinets (5–10% RH) for extended shelf life.
Consumer Electronics: Safeguarding components like hard drives, memory modules (DDR4, DDR5), and power management PCBs in repair and warranty services.
Automotive Electronics: Shielding ECUs (engine control units) and sensors (ABS, airbag) from ESD in under-hood and cabin environments.
Q: Can these bags be used for vacuum packaging?
A: Yes, they are compatible with vacuum-sealing processes (operating pressure: -0.07 to -0.09 MPa) to extend shelf life, with heat-sealed seams maintaining integrity under vacuum for 6+ months.
Q: Are they certified for ESD compliance?
A: Yes, they meet ANSI/ESD S20.20 and IPC/JEDEC J-STD-033 standards, with third-party certification from UL or ESD Association available for critical applications.
Q: What is the typical lead time for custom orders?
A: Custom sizes (minimum 100x150mm) and printing require 8–20 working days, with expedited options (5–7 days) available for orders >10,000 units.
Q: Do they come in different colors?
A: Most bags are silver due to the aluminum layer, but custom colors (black, blue) are available via pigmented PE layers, with minimum order quantities starting at 5,000 units.
