What's Anti Static Bubble Bags
An anti-static bubble bag is a type of bag, typically made of polyethylene, used for storing and protecting sensitive electronic components that are can be damaged by electrostatic discharge (ESD).
What are the functions of Anti-static Bubble Bags?
An anti-static bubble bag provides dual benefits when packaging sensitive items: protection against the packaging itself creating a static discharge and the bubble wrap providing physical protection of the packaged product.
At present, the surface resistance test method and static induction peak voltage test method of antistatic shielding bubble bag in the market are characterized by using HBM model close to the actual environment, replacing voltage probe with current probe that does not affect the measuring circuit, and using 2000 MHZ bandwidth 500MS/S sampling rate oscilloscope to cover a wider frequency range to reduce error.
The advantages and disadvantages of electrostatic shielding performance are described from the point of view of energy.
What Are the Anti-static Performance Standards?
The main standards of anti-static shielding bubble bags:
GB/12367-90 "painting operation safety regulations electrostatic spray painting process safety",
GB/13348-92 liquid petroleum products electrostatic safety regulations,
GJB/Z 86Mel 97 "electrostatic discharge protection packaging manual"
GJB/2605-96 "flexible thermal sealing anti-static electrical barrier material specification" and so on.
How To Test the Anti-static Bags ?
there are two methods to test the antistatic shielding bubble bag in the domestic testing market: the surface resistance test method and the static induction peak voltage test method.
The surface resistance test method is to test the resistance of the inner and outer surface of the electrostatic shielding bubble bag.
The national military standard GJB2605-96 "specification for heat-sealing flexible antistatic barrier materials" requires that the inner surface resistivity is 1*10E5 ohms-1*10E12 ohms, and the surface resistivity is less than 1*10E12 ohms.
This method intelligently tests the surface resistance of the inner and outer surface of the antistatic shielding bubble bag, rather than the test of the antistatic shielding bubble bag shielding layer, so the test results can not reflect the electrostatic shielding performance of the antistatic shielding bubble bag. there is a difference between the test results and the shielding performance test requirements.
