Anti-Static Bags & ESD Packaging Supplies for Shipping Electronics

SupplyLand stocks anti-static packaging supplies for electronics manufacturers, distributors, and repair facilities that need reliable ESD protection at every stage of handling. Our anti-static flat bags and reclosable anti-static bags are made from pink or metal-in poly film that dissipates static charge before it can damage circuit boards, semiconductors, or sensitive assemblies. For components that need cushioned protection as well as static control, our anti-static bubble pouches combine ESD-safe film with bubble cushioning in a single bag.

When standard static control is not enough, our static shielding bags provide a metal-in barrier that blocks electrostatic fields from reaching the contents, the preferred choice for bare PCBs, memory modules, and MIL-SPEC shipping requirements. All ESD bags in our catalog meet industry standards for static decay and surface resistivity. Order in bulk to keep your packaging line stocked, or mix styles to match your product range. Pair with foam cushioning or bubble and cushioning materials for complete ESD-safe packing solutions.

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

Anti-static bags, including pink poly flat bags and reclosable bags, are made from a surface-resistive material that prevents static buildup on the outside of the bag. They work well for loose components, assemblies inside equipment, or items that will not be exposed to an electrostatic field during transport. Static shielding bags use a metal-in construction that creates a Faraday cage effect, blocking external electrostatic fields from reaching the contents. They are the correct choice for bare PCBs, memory modules, drives, and any ESD-sensitive device being shipped or stored outside of a protected work area.

Are anti-static bags reusable?

Reclosable anti-static bags are designed for repeated use and can be resealed with their zip-lock style closure after each access. Flat bags are typically sealed by heat or fold-over tape and are intended for single-use applications. Static shielding bags with resealable closures can also be reused, but inspect for pinholes or tears before reuse. Any breach in the metal-in layer compromises the Faraday shielding. For high-volume or cost-sensitive applications, single-use flat bags often provide a better per-unit cost than reusable options.

What sizes of anti-static bags does SupplyLand carry?

SupplyLand carries anti-static bags in a wide range of sizes to fit small components like chips and connectors up to large assemblies and motherboards. Flat bags are available in sizes starting from 2" x 3" up to 18" x 24" and larger. Reclosable bags and bubble pouches are stocked in common electronics packaging dimensions. If you need a size not shown, contact us for custom or case-quantity options.

Do anti-static bags meet MIL-SPEC or industry standards?

Many ESD bags in our catalog are manufactured to meet ANSI/ESD S11.4 for static shielding bags and ESD S11.31 for flexible materials. Static shielding bags with metal-in construction are commonly specified for MIL-PRF-81705 compliance, which covers barrier materials used in military and aerospace electronics packaging. Check individual product listings for specific standard callouts, or contact SupplyLand for documentation if compliance verification is required for your application.

How should I store anti-static bags when not in use?

Store anti-static bags flat in a cool, dry environment away from direct sunlight and heat sources. UV exposure and heat can degrade the static-dissipative additives in pink poly film over time, reducing effectiveness. Keep bags in their original packaging or in sealed cartons until use. For static shielding bags, avoid folding sharply or creasing the metal-in layer, which can create pinholes that compromise the shielding barrier. Most ESD bags have a shelf life of two to three years under proper storage conditions.
