The Different Types of Anti-Static Bags Explained (Pink, Black, and Silver Shielding)
22 Oct 2025

When it comes to packaging sensitive electronic components, choosing the right type of anti-static bag is crucial. Static electricity can damage delicate circuits, microchips, and semiconductors long before you even realize it’s happened. That’s where anti-static bags come in — they’re specifically designed to protect components from electrostatic discharge (ESD). But not all anti-static bags offer the same level of protection.
At Atlantic Poly, Inc., we offer several types of ESD-safe bags to match your product’s specific needs. Here’s a breakdown of the most common types:
1. Pink Anti-Static Bags
Protection level: Basic
Best for: Packaging non-sensitive components or items used in ESD-controlled environments
Pink anti-static bags are the most recognizable type, often made from polyethylene with an additive that dissipates static charges. While they don’t shield against external static fields, they prevent the buildup of static electricity within the bag itself.
Use these when you’re packaging hardware components, connectors, or plastic parts that don’t require high-level shielding.
2. Black Conductive Bags
Protection level: Moderate
Best for: Storing and transporting semi-sensitive electronic parts
Black conductive bags are made with carbon-loading materials, giving them a surface that can conduct electricity and safely dissipate static charges. They provide more protection than pink bags by offering a degree of shielding against static fields.
They’re a great choice for circuit boards, processors, and assembled electronic components that need mid-level ESD protection during transport or storage.
3. Silver Shielding Bags
Protection level: High
Best for: Sensitive electronic components and assemblies
Silver shielding bags are the top-tier choice for ESD protection. These multilayer bags feature a metallized polyester layer that creates a Faraday cage, blocking both static and electromagnetic fields.
These are commonly used for high-value electronics such as hard drives, semiconductors, and microprocessors. They offer the most complete protection from static discharge — both inside and outside the bag.
Choosing the Right ESD Packaging
The right anti-static packaging depends on your product’s sensitivity level, handling environment, and storage conditions. Using the correct type ensures your components arrive intact and ready for use — without costly static-related damage.
At Atlantic Poly, Inc., we provide a full range of anti-static and static-shielding bags in custom sizes, colors, and thicknesses to meet your industry’s exact standards.
Protect Your Products the Right Way
Whether you need pink anti-static bags for general use or silver shielding bags for advanced electronics, Atlantic Poly, Inc. has you covered.
