Detect the anti-static function of the esd bubble bag
Surface resistance tester can be used to test its surface resistance, and static voltage to test its friction voltage, which is lower than 100V and meets the standard.
Another simple method is to gently rub a pinch of bubble bags, and then put the bubble bag against the dusty place, see if the bubble bag sucks the dust? If vacuuming, the effect is not very good.
