AN ELECTROSTATIC SHIELDING, LOW CHARGING-RETAINING MOISTURE BARRIER FILM

摘要

A film material for use in packaging electrostatically sensitive components and corrosion sensitive components. The film material includes a static dissipative polymer (1) attached to a first moisture barrier (2) which in turn is attached to a second moisture barrier (3). The second moisture barrier has a low charge retaining coating (4). Moisture barriers are formed by either a metal foil, or a metallized polymer in which the thickness is at least 178 Angstroms thick. The metal of the second moisture barrier (8) is in contact with the low charge retaining coating.
