Due to rubbing and separation of two materials, electric charges of up to 35,000 volts can occur. But even a charge of 20 volts can damage or destroy sensitive electrical components, when a sudden discharge happens. The conductive folding boxes illustrated here (ESD) are made of a electro-conductive plastic, to avoid the build up of these charges. Folding boxes made of conductive material not only save space, but transport your electronic components securely.
