An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film , pink or black for polyethylene ).
Most garments are not conductive enough to provide personal grounding, so antistatic wrist and foot straps are also worn. There are three types of static control garments that are compliant to the ANSI/ESD S20.20-2014 standards: 1) static control garment, 2) groundable static control garment, 3) groundable static control garment system.

In response to this problem, Robert F. Gabriel, a Systems Engineer at Sperry Univac devised a large number of possible symbols that could be affixed to parts, packaging, and PCBs to alert the user that the part is ESD-sensitive. Gabriel developed a proposal for an ESD warning symbol and circulated it to numerous electronics standards groups. C.
It was developed by Custom Materials, now part of 3M. [2] Velostat is a U.S. registered trademark (4,964,564) of Desco Industries Inc. Desco Industries purchased the assets of the 3M Static Control business on January 2, 2015. [3] Velostat is piezoresistive; its resistance changes with flexing or pressure.
Conductive ESD bag with a network card inside ESD shoes. Electrostatic discharge materials (ESD materials) are plastics that reduce static electricity to protect against damage to electrostatic-sensitive devices (ESD) or to prevent the accidental ignition of flammable liquids or gases.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static electricity. Static charge may be generated by the triboelectric effect [1] or by a non-contact process using a high voltage power source. Static charge may be introduced on a surface as part of an in-mold label ...
3M made $35.4 billion in total sales in 2021 and ranked number 102 in the Fortune 500 list of the largest United States corporations by total revenue. [10] As of 2021, the company had approximately 95,000 employees and operations in more than 70 countries. [11] There are a few international subsidiaries, such as 3M India, 3M Japan, and 3M Canada.
