Grid Shield bags and zipper bags  Grofit Plastic Grid shield bags are designed for products requiring ESD protection, Grid shield bags are made with a high performance conductive grid. The bags may be reused without loss of conductivity. Our Grid shield bags offer transparency and are humidity-independent. An inner layer of amine-free, static-dissipative polyethylene provides protection from tribocharging. PERFORMANCE Surface Resistivity Inner layer 10^10~10^12 ohms Surface Resistivity outer layer 10^3~10^5 ohms Static decay rate 1.6 sec FED STD 101C Triboelectric charge 0.12 NCB/SQ INCH EIA 541             ANTI STATIC PACKAGING Our Amine free Anti-static packaging is manufactured from low density Polyethylene impregnated with an antistatic which constantly migrate to the surface forming a layer that increases the material's lubricity. This packaging meets the requirements of Military Specification MIL-B-81705, type II. Our Anti-static flexible packaging is electrostatic-free, heat-sealable and is static dissipative. Surface resistivity, according to ASTM Method D-257-66 is lower than 10" Ohm/cm
