  • Method of making a flexible, transparent film for electrostatic shielding
    Patent number: 5165985
    Abstract: A method of making a flexible, transparent film providing electrostatic shielding by applying a plurality of thin, conductive slivers to a sheet having a dimensionally stable layer and a thermoplastic layer, the slivers being applied to the thermoplastic layer, and then laminating a cover sheet over the thermoplastic layer, the cover sheet being formed of the same material as the thermoplastic layer. The thermoplastic layer is heated to its melting pint, and the cover sheet is extruded and laminated in a molten state whereby the cover sheet blends with the thermoplastic layer to form a single, homogenous layer. The slivers form an essentially two-dimensional, conductive network which is suspended in the homogenous layer.
