Electronic Component Foil Bag

Electronic component foil bags,also called ESD aluminum foil shielding bags,are high-performance multi-layer laminated packaging designed exclusively for static-sensitive and precision electronic parts.They integrate electrostatic discharge(ESD)protection,moisture/oxygen/light barrier,and electromagnetic interference(EMI)shielding in one structure,safeguarding components from damage during handling,shipping,and long-term storage.

1.Material Structure(3–4 Layer Lamination)

Built with food/industrial-grade films+pure aluminum foil(AL)core;customizable for strength and barrier needs:

Outer PET/BOPP Layer:High tensile strength,scratch resistance,and printability for logos/specs.

Core AL Foil Layer:Ultra-high barrier(0 oxygen/moisture/light transmission);creates a Faraday cage to block ESD and EMI.

PA/Nylon Reinforcement(Optional):Boosts puncture/tear resistance for heavy/sharp components.

Inner PE/CPP Layer:ESD-safe,heat-sealable,and cleanroom-compatible for direct component contact.

Common Structures:PET/AL/PE,PET/AL/PA/PE,PET/AL/CPP(high-temp resistant).

2.Core Technical Advantages

✅ESD Protection&EMI Shielding

Surface resistance:10⁷–10¹¹Ω(meets ANSI/ESD S20.20,MIL-PRF-81705).

Static decay time:<0.03–0.05 s;EMI attenuation:≥45 dB.

Shields sensitive ICs,PCBs,and semiconductors from electrostatic breakdown and EMI interference.

✅Ultra-High Barrier Performance

Moisture-proof:MVTR<0.01 g/m²/24h;prevents corrosion and short circuits.

Oxygen/light-proof:Blocks oxidation and UV aging;extends shelf life by 30–50%vs.standard ESD bags.

Vacuum-sealable:Ideal for long-haul shipping and humidity-prone regions.

✅Durability&Temperature Resistance

Withstands-50°C to 121°C;suitable for freeze storage and high-temperature assembly environments.

Puncture/tear-resistant;fits 0.5g–10kg components(chips,wafers,sensors,etc.).

✅Compliance&Safety

RoHS,REACH,and IPC/JEDEC J-STD-033 certified;low-dust,cleanroom-safe(Class 100–1000).

Non-toxic,non-contaminating;no silicone or halogen residues.

3.Common Bag Types

3-Side Seal Flat Bags:Cost-effective for small parts(ICs,resistors,capacitors).

Stand-Up Pouches:With bottom gusset for stable display;ideal for reels/trays.

Zipper Bags:Reclosable for repeated use;perfect for prototype samples.

Vacuum Bags:For hermetic sealing of moisture-sensitive components(e.g.,MEMS,LEDs).

4.Applications

Semiconductors:ICs,CPUs,GPUs,memory chips,wafers,and bare dies.

Circuit Boards:PCBs,FPCs,and SMT assemblies.

Precision Components:Sensors,connectors,relays,and optoelectronic devices.

High-End Electronics:Medical electronics,automotive chips,and aerospace components.

5.Customization

Sizes:50mm–1500mm width;custom lengths.

Printing:High-definition logos,ESD symbols,part numbers,and QR codes.

Finishes:Matte/glossy surfaces;transparent window options.

Accessories:Easy-tear notches,hang holes,and resealable zippers.
