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

These plastic bags normally and have a distinctive colour according to its properties:

• Silver for metallised PET film and other similar plastics
• Pink or black for polyethylene

Where the polyethylene model can also be made as foam or bubble wrap, either as sheets or bags.

To create the anti-static effect, the black bags or silver bags are made of standard polyethylene with a static dissipative coating or layer on the plastic. This prevents buildup of a static charge on the surface of the bag, as it dissipates the charge to ground. This forms both a shield and a non-conductive barrier, shielding the contents from static charge during handling.
