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 |
Multi-Layer Aluminum Foil Antistatic Bags for PCB combine aluminum foil (12–25μm thickness) and static-dissipative polymers to create a robust barrier against ESD, moisture, and physical damage. Their four-layer structure (PET/aluminum foil/nylon/PE) integrates the barrier properties of metal with the flexibility of plastics, ensuring optimal performance in high-precision electronics applications. These bags are widely used in PCB fabrication, SMT (surface mount technology) lines, and electronic component storage, with a 92% customer retention rate in PCB manufacturing sectors.
Aluminum foil layer provides 60 dB EMI shielding (30 MHz–1 GHz), blocking external electrostatic fields and reducing ESD-induced failure rates by 70%.
Static-dissipative inner layer (PE) prevents charge accumulation, with surface resistivity of 10⁸–10¹¹ ohms (per STM11.11) and charge decay time <0.5 seconds.
Low moisture vapor transmission rate (MVTR <0.05 g/m²/24h) and oxygen transmission rate (OTR <1 cm³/m²/24h) ensure long-term protection against corrosion and oxidation, suitable for 12+ month storage.
Tensile strength of 3,800 psi (per ASTM D882) and puncture resistance (16 lbs force) withstand harsh handling in automated packaging lines and international shipping.
Nylon layer enhances flex crack resistance, maintaining integrity after 500+ folding cycles.
Vacuum Packaging Compatibility:
Ideal for dry packaging of PCBs and ICs, maintaining vacuum integrity (≤-0.09 MPa) for up to one year, with heat-seal strength ≥5 N/15mm to prevent air leakage.
PCB Fabrication: Protecting bare boards during chemical processing (etching, plating) and transportation between manufacturing stages.
Semiconductor Packaging: Safeguarding ICs, diodes, and transistors from ESD and moisture in wafer fabs and assembly plants.
Aerospace Electronics: Shielding high-reliability components (avionics PCBs, sensor modules) in extreme environments (-40°C to 85°C).
Medical Devices: Ensuring sterile packaging for electrostatic-sensitive medical equipment (MRI components, diagnostic sensors) in ISO 13485-certified facilities.
Q: Can these bags be printed with logos or labels?
A: Yes, custom printing is available on the outer PET layer using solvent-free inks, with options for barcodes, QR codes, and compliance marks (e.g., RoHS, REACH) for traceability.
Q: What is the shelf life of these bags?
A: When stored in a dry environment (15–30°C, relative humidity <60%), they remain effective for up to 24 months from the production date, with shelf life extensions possible under controlled conditions.
Q: Are they RoHS compliant?
A: Yes, materials used comply with RoHS directives (2011/65/EU), restricting lead, mercury, and other hazardous substances to <0.1% by weight.
