ABSTRACT:
A flexible sheet material for forming an envelope used to enclose and protect electronic components from electrostatic charges during storage and shipment. The sheet material is sufficiently transparent to afford visual identification of an electronic component through the envelope, while including a polymeric sheet having a high volume resistivity to electrically isolate a component within the envelope, an antistatic material which is disposed at an inner surface of the envelope for dissipating and restricting electrostatic charges on components within the envelope, and a highly conductive layer which is then disposed on the outer surface of the polymeric sheet and provides a highly conductive outer surface on the envelope for grounding electrostatic charges brought into contact with the envelope.
