The blake PE conductive  bag is blown molded from LDPE,cavitation agent and super conductive carbon black by special machinery.This bag has good electrostatic discharge perf-ormance and mechanical performance.The  electric charges accumulated on the bag and its inside work pieces can be well discharged from the bag. Besides,the bag has good conductiveity and light-proof performance,capable of protecting sensitive electronic components from damage of electroma-gnetic wave and static,and also applicable to pack light -sensitive components or products with special packaging requirements.With a surface resistance of it mainly applies to military industry,network communication, light-sensitive equipment,apparatus,instrument.
