Metallised Bags also known as conductive bags, operate by using a layer of conductive metal and a dielectric plastic layer. They create their own Faraday cage effect. With a dissipative coating, these static shielding bagsnot only prevent static discharge from building up but also protect from contact with a static charge. These bags are reclosable and come in various types including zipper, heat sealable, self-sealing and open-topped. Some metallised bags also offer a moisture barrier for a long-term storage solution.

This kinds of bags are widely used in applications including semiconductor and PCB manufacturing, aerospace, medical, and other ESD sensitive environments.
