What is the difference between anti-static shielding bags and static dissipative bags?



The three electrostatic control characteristics of electrostatic packaging are:
1. Low charge (improperly called antistatic)
2. Dissipative or conductive
3. Shielding
Antistatic is a property known as "low charge". This is an important feature for all ESD protective packaging inside the bag, so there is no (or minimal) tribo-charging of ESD sensitive devices when inserted into the bag. All of our bags have this feature. Dissipation is an electrical property of resistance that infers high resistance ranges (significantly slows down current transfer). ESDA's standard ANSI/ESD-S20.20 states that a dissipative package should be less than 1x10 11 ohms resistor (or <1x10 12ohms resistivity), but greater than or equal to 1x10 4 ohms. All of our bags meet this standard.
