<p>The present invention discloses a low cost static shielding multilayer film (30) which including an innermost skin layer (32). The innermost skin layer (32) is intended to be in contact with an electro-static discharge sensitive component or device. The innermost skin layer (32) is rendered an intrinsically permanent and non-migratory static dissipative property in a co-extrusion process. A non-migratory anti-static chemical additive is added, at a pre- determined concentration, to a bulk resin making up the innermost skin layer (32). This mixture is then extruded to form the innermost skin layer (32). Essentially, the innermost skin layer (32) is included in the film (30) of multiple-layer construction with static shielding and static dissipative properties. Five embodiments are disclosed. The exact number of layers in the multiple-layer construction varies. Like sub-layers are grouped as one layer categorically.</p> |
