Anti-static Aluminum Foil Bag | 7-Micron Barrier Film

Our anti-static aluminum foil bag is the complete ESD and moisture protection solution for sensitive electronic components — combining electrostatic shielding, moisture barrier performance, and anti-static surface properties in a single, certified packaging material. Compliant with IEC 61340-5-1 and ANSI/ESD S20.20 ESD control standards, these bags are the specification-grade choice for semiconductor manufacturers, electronics distributors, and procurement managers across Southeast Asia.

Electronic components are simultaneously vulnerable to two distinct threats: electrostatic discharge (ESD) and moisture. Standard anti-static bags address ESD but provide no moisture protection. Standard moisture barrier bags may not address ESD. Anti-static aluminum foil bags resolve both requirements in a single packaging solution — eliminating the need for double-bagging or separate ESD and moisture barrier packaging stages in the production process.

Key Features

Dual Protection: ESD + Moisture

The aluminum foil core creates a Faraday cage that shields packaged components from external electrostatic fields, while simultaneously providing near-zero WVTR moisture barrier performance. No other single packaging material delivers both capabilities at this performance level.

IEC 61340 Compliant

Anti-static inner layer with surface resistance in the dissipative range (10⁴ – 10¹¹ Ω) prevents charge buildup on the bag surface and charge transfer to component surfaces on contact. Electrostatic shielding performance meets the <20 nanojoule energy requirement of IEC 61340-5-3.

Anti-static Inner Layer

The inner PE layer is formulated with anti-static additives, preventing triboelectric charge generation on contact with component surfaces. This is critical for preventing charged device model (CDM) ESD events during bag opening and component removal.

Third-party Test Documentation Available

Surface resistance measurements, shielding effectiveness data, and WVTR test reports available on request — supporting your quality management system and customer audit requirements.

Custom Sizes and Configurations

Available in heat-seal and zip-lock configurations, all custom dimensions. Small batch orders supported.

Applications

Anti-static aluminum foil bags are the standard packaging solution for semiconductors, ICs, microprocessors, BGA packages, and other ESD-sensitive components requiring simultaneous moisture and electrostatic protection. They are used throughout electronics manufacturing supply chains — from component manufacturer shipping to distributor storage, and from distributor stock to PCB assembly line delivery.

For electronics manufacturers across Southeast Asia sourcing anti-static aluminum foil bags, the critical verification step is requesting third-party test documentation — not accepting supplier self-declaration of compliance. Surface resistance measurements referencing IEC 61340-5-3, shielding effectiveness data confirming energy below 20 nanojoules, and WVTR data confirming moisture barrier performance are the three documents that distinguish a compliant anti-static aluminum foil bag from a non-compliant alternative marketed with the same product name.

Frequently Asked Questions

Q: What is the difference between anti-static bags and ESD shielding bags?

Anti-static bags prevent charge buildup on the bag surface but do not shield against external electrostatic fields. ESD shielding bags (including anti-static aluminum foil bags) create a Faraday cage that blocks external fields from reaching components inside. For sensitive semiconductors and ICs, shielding bags are the correct specification.

Q: Do anti-static aluminum foil bags meet IEC 61340 standards?

Yes. Our anti-static aluminum foil bags are manufactured to meet the requirements of IEC 61340-5-1 (ESD control program requirements) and IEC 61340-5-3 (packaging material classification and performance). Test documentation is available on request.

Q: How do I verify ESD compliance from a supplier?

Request third-party surface resistance test reports (referencing IEC 61340-5-3) and shielding effectiveness data confirming energy inside the bag is less than 20 nanojoules. A supplier unable to provide this documentation cannot confirm compliance.

Q: Are custom sizes available?

Yes. All dimensions custom manufactured. Small batch orders welcome.
