- PCBs & Electronic Assemblies – Circuit boards and sub-assemblies
These bags are particularly suitable for in-plant handling, warehousing, inventory management, retail display, and inter-facility transport of ESD-sensitive components.
Industry Standards & Compliance
ZXCOOL’s anti-static ESD bags meet or exceed key industry requirements:
ANSI/ESD S20.20 & ANSI/ESD S541
Meets packaging material requirements for electrostatic discharge (ESD) control programs. The bags fall within the dissipative range (surface resistance of 10⁴ to 10¹¹ Ω) as defined by ANSI/ESD S541. Packaging materials in intimate contact with devices should be dissipative to safely conduct charges to ground.
ANSI/ESD STM11.11
Surface resistance testing conforms to the ESD Association’s standard test method for measuring surface resistance of packaging materials.
Environmental Compliance
Made from high-quality PET with aluminized film—non-toxic, odorless, and eco-friendly. Meets environmental requirements for safe handling and disposal.

We ship thousands of hard drives monthly to data center clients worldwide, and these anti-static bags have significantly reduced our ESD-related failure rates. The 15×20cm size fits standard 3.5″ drives perfectly — not too tight, not too loose. What truly sets these apart is the anti-static coefficient of ≥10¹⁰, which is noticeably higher than the typical 10⁸–10⁹ bags we tested from other suppliers. The PET/aluminized film construction provides excellent moisture resistance (Class II), which is critical for sea freight shipments that may sit in humid containers for weeks. We also appreciate the reusable zip-lock — our warehouse team can open bags for inspection and reseal them without compromising protection. The semi-translucent design allows for quick visual verification without opening, streamlining our inventory checks. A reliable, cost-effective solution that we will continue using.

These anti static bags are exactly what I needed for storing and transporting electronic components. The material feels thick and durable, and the seal closes securely. The size is accurate and works well for small circuit boards, hard drives, and other sensitive parts.
They provide good protection against static and help keep components safe from dust and damage. The pack of 100 is a great value, especially if you work with electronics regularly. I would definitely order them again.

We’re a PC assembly shop in Ho Chi Minh City, handling hundreds of hard drives weekly. These 15×20cm bags fit 3.5″ HDDs like a glove – no extra space, no sliding around. The aluminized layer gives solid ESD and moisture protection, and the resealable zip is convenient for inventory checks. Great value – we’ll keep ordering.
