Abstract
A polymeric laminate and packaging material produced therefrom have (a) at least one conductive layer and (b) at least one static dissipative layer comprising a polymer composition having dispersed therein a non-volatile ionizable metal salt, said static dissipative layer being in electrical contact with the conductive layer. Such a laminate is found to provide shielding and static dissipation suitable for packaging of electrostatically sensitive items such as electronic components.
