Stable prescription bags and anti-static bags serve various purposes in electrostatic security. Statical preservation bags provide a conductive barrier that prevents electrostatic discharge (ESD) from reaching sensitive electronic components. They create the effect of a Faraday cage, blocking external static charges. On the other hand, anti-static bags, prevent static electricity manufacturing, but do not protect from direct ESD exposure. Anti-static bags are usually pink or blue and are used for non-sensitive items, while stable prescription bags, often ideal for highly sensitive electronics such as silver, circuit boards and semiconductors. Choosing the right bag depends on the level of necessary safety.
