Static Shielding

What Does Static Shielding Mean?

Static shielding is the two-fold process of preventing the build-up of static electricity and electrostatic discharge (ESD). In other words, a shielded material does not accumulate charge and is also prohibited from receiving a charge from or transferring a charge to other objects. Static shielding bags, for example, protect components from static charges from both inside and outside the container.

The most common material for constructing static shielding bags is polyethylene terephthalate (PET).


Corrosionpedia Explains Static Shielding

Static shielding is typically confused with anti-static protection. Anti-static bags only prevent the build-up of static electricity from within the bag. However, they will not prevent a charge from being transferred from one component to another (an ESD). In this regard, anti-static bags are ideal for packaging items that are sensitive to charge build-up, like electronics.

Static shielding bags are ideal for safely transporting components from an EPA (ESD protected area) to a non-EPA. Its effectiveness is due mainly to a phenomenon known as the Faraday cage effect.
