A conductive enclosure used to block electrostatic fields is also known as a Faraday cage. The amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of holes in a shield to an incident electromagnetic field.

An EMP such as a lightning strike can physically damage objects such as buildings and aircraft. The management of EMP effects is a branch of electromagnetic compatibility (EMC) engineering. The first recorded damage from an electromagnetic pulse came with the solar storm of August 1859, or the Carrington Event. [2]
The buildup and discharge of static can be minimized by controlling the surface resistance and volume resistivity of packaging materials. Packaging is also designed to minimize frictional or triboelectric charging of packs due to rubbing together during shipping, and it may be necessary to incorporate electrostatic or electromagnetic shielding ...
Testing modified atmosphere in a plastic bag of carrots. Food packaging is a packaging system specifically designed for food and represents one of the most important aspects among the processes involved in the food industry, as it provides protection from chemical, biological and physical alterations.

A packaging gas is used to pack sensitive materials such as food into a modified atmosphere environment. The gas used is usually inert , or of a nature that protects the integrity of the packaged goods, inhibiting unwanted chemical reactions such as food spoilage or oxidation .
If there is an air gap (or at least, poor thermal contact) between the susceptor and food, the susceptor will heat to a much higher temperature (due to its smaller effective heat capacity when in poor contact with food), and, at these higher temperatures, will radiate strongly in the infrared. This infrared radiation then shines onto the food ...
A network card inside an antistatic bag. A pink static dissipative bag, and a silver conductive bag. Note the two recurring ESD symbols. An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD).
