Shielding bags (anti-static bags, static bags, silver shielding bags, PET-static bag): shielding bag: the bags can maximize the protection of static sensitive components from electrostatic potential hazards. Their unique four-layer structure can be formed "induction hood" to protect the bag of goods and electrostatic field isolation. In addition there is a layer consisting of vinyl to eliminate static, anti-static function is superior, the electrostatic field is slow, safe discharge, which can be heat sealed bags are translucent, easy to observe, does not affect the bar code reader, mainly for electronic components, PC boards, etc ...... packing. Surface resistance: 108 ~ 1011Ω.
