Antistatic bag

An antistatic bag is a bag used for shipping (usually electronic) components, which are prone to damage caused by electrostatic discharge.

These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film, pink or black for polyethylene). The polyethylene variant may also take the form of foam or bubble wrap, either as sheets or bags. Multiple layers of protection are often used to protect from both mechanical damage and electrostatic damage. A protected device can be packaged inside a metalized PET film bag, inside a pink polyethylene bubble-wrap bag, which is finally packed inside a rigid black polyethylene box lined with pink poly foam.

To create the anti-static effect, the black or silver bags are slightly conductive, forming a Faraday cage around the item to be protected and preventing any localized charges from being deposited onto the protected devices as the bags are handled. The pink or green bags are made of low-charging material that will not create harmful charges, but that does not protect the item from electric fields.^[1] It is important that the bags only be opened at static-free workstations.^[2]
