With electronic components getting smaller and more sensitive, it’s important to make sure they are protected from ESD events like static discharge. Per ANSI/ESD S20.20, “Protective packaging is required to store, transport, and protect ESDS electronic items during all phases of production.” Per the new 2018 requirements for ANSI/ESD S541, the shielding requirement was changed that remaining discharge for the bags should be less than 20 nanojules.
One of the more common used bags is a low charging Pink Poly bag. These bags are made from a tinted polyethylene material with an antistatic coating that can wear away. This turns the bag insulative over time, making it noncompliant to ANSI/ESD S541 recommendations. They also lack discharge shielding protection which makes components within the bag susceptible to ESD event damage. Metallized Shielding bags are constructed from a metalized polyester film and a low charging polyethylene laminate. This provides the bags with a shielding layer that creates a Faraday cage protecting the ESD sensitive components within the bag from possible ESD event damage. The low charging inner layer and outer layer of the bag prevent tribocharging from occurring, minimizing the build up of ESD charges when handling components.
