ABSTRACT:
There is here provided an electroconductive thermoplastic sheet prepared by superposing, upon either surface or both the surface of a thermoplastic film, or sheet an electroconductive nonwoven fabric formed by irregularly twining an electroconductive fiber into a hot-melt adhesive fiber, further superposing, upon the outer side of the electroconductive nonwoven fabric, a nonwoven fabric made from the hot-melt adhesive fiber to obtain a laminate, and fusing the laminate integrally.
The sheet of the present invention retains transparency and electroconductivity, and it is suitable for, for example, materials for packing of electronic parts and precision instruments where dust deposition and static electricity obstruction should be avoided.
