Electrostatic Discharge (ESD) Bags, Pouches & Packaging

ELECTROSTATIC DISCHARGE BAGS

When you need to protect sensitive products — such as electronic components — that are susceptible to damage or even explosion from electrostatic discharges, look no further than Caltex Plastics. Our wide assortment of ESD static shielding bags are durable and economically priced — and they provide excellent Faraday cage performance.

In addition to our wholesale static shielding bags and black conductive plastic packaging, we offer MIL-SPEC-qualified static-shielding bags for robust protection of military components and munitions. Businesses ranging from electronics manufacturers to defense contractors trust the name Caltex because they know our products and services are among the best in the business. For well over 30 years, we’ve been providing our customers with one of the largest selections of rollstock. Plus, we operate on a 24/7 schedule so that both small and large orders are filled quickly and affordably.

CHARACTERISTICS & APPLICATIONS

Static shielding bags are primarily used to store items like printed circuit boards, network cards and other pieces of electronic circuitry that may be impaired if they come in contact with an electrostatic discharge — or ESD. The level of sensitivity of some components can be so great that even an electric shock from the touch of a human hand can harm their performance.

With such varying applications — from advanced electronics to military-grade items — antistatic bags are a primary method of packaging, storing and transporting items with ESD sensitivity. Quite often, these types of bags are made from polyethylene and polyethylene terephthalate — or PET — and are recognizable by their characteristic colors, such as silver, pink and black.

In addition to pouches and bags, antistatic packaging material can also take the form of bubble wrap and other types of sheeting. Multiple static-proof layers of protection are often needed to meet a specific industry’s requirements for the safe handling, shipping and transportation of sensitive items.

The construction of antistatic bags is often accomplished by layering in the form of a black conductive metal — such as aluminum — along with a plastic layer that’s dielectric thanks to a coating that allows it to dissipate static. The result is a shield as well as a barrier that’s non-conductive and forms a protective space with the same characteristics of a Faraday cage.

As an example of our ESD packaging materials, we offer CP BLACKSTAT that’s made from compressed carbon combined with polyethylene. Its multilayer design provides excellent protection for everything from electronic components to explosive devices that are susceptible to any forms of sparking. In addition, it provides protection against abrasions, ultraviolet light and even moisture if the bag is heat sealed.

For an economical way of protecting components against ESD and moisture, we offer CALDRY 100 as an alternative to more expensive nylon/foil laminates. With a multi-layer composition and a low MVTR, CALDRY 100 offers cost-effective protection against static fields, moisture and tribocharging.
