theory：
Anti-static shielding bag can prevent static sensing element from potential electrostatic hazard, the special four-layer structure can form inductive hood effect which prevents the goods inside from static electric field. In addition, the interior layer was made of polyethylene which with anti-static property, this kind of heat sealable bag is translucence, so the goods inside can be easily recognized outside

application：anti-static shielding bag mainly used in various PC board, electronic building brick modem and CD-ROM packaging
