It is a common notion that static electricity in different materials such as clothes, hair, etc. can damage electronic devices. This damage can be irreversible if the static electricity reaches the internal circuits. This process is known as ESD (electrostatic discharge), and itÔÇÖs one of the main causes why electronic circuits stop working. For this reason, many electronic circuitsÔÇÖ packaging comes with a label warning users of the ESD risk. (Related topic: protective packaging)

Below, we will talk about three different types of bags that prevent electronic circuits from getting damaged because of ESD.
Anti-Static Bags
These are typically covered with a compound that helps to minimize ESD either by friction or induction. It should be covered on both sides.
ESD Bags
These are bags with resistant surfaces. Most people prefer these types of bags because they protect from the electronic discharge through the surface and at a controlled speed. They also are anti-static. Static shielding bags are recommended for being used in any non-critical environment.
Static Shielding Bags
ESD bags are protected by a metallic layer in the inside. This layer┬áacts as a shield against electronic discharges that come from outside the bag. Depending on the energy, the dischargeÔÇÖs duration and thickness of the metallic layer, an ESD event normally deviates towards the metalÔÇÖs external surface. This effect is known as the Faraday cage or Faraday shield.
We hope this article has been helpful to you. By knowing about the different types of bags to protect your products from electronic discharge, you will ensure that your customers receive an intact product all the time.
