The kind of bag can keep static-sensitive components away from the potential static danger to the largest extent. Its special four -layer structure can create such effect as an inductive cover to separate the goods inside from the static field. Furthermore, the inner layer is made from ethane which can remove the static and avoid static generation inside the bag. In addition, this kind of hot seal bag is transparent, so the goods inside can be easily recognized from outside. And the surface resistance: 108～1011Ω.
