The invention provides an antistatic metal foil and plastic composited belt for symmetric data cable shielding. The antistatic metal foil and plastic composited belt comprises a metal layer and a nonmetallic layer which are adhered by adhesives, and antistatic substances are added in the nonmetallic layer. Shielding materials are broken through, the metal layer and the nonmetallic layer are combined, the surface of the nonmetallic layer is coated with an antistatic substance layer or the antistatic substances are directly added in the nonmetallic layer, so that the metal foil and plastic composited belt has antistatic property, and noise interference of wires caused by static interface due to bending or twisting during wiring and use is effectively eliminated. Symmetric data cables for Ethernet meet requirements for mechanical performance and electric performance of Telecommunications Industry Association (TIA) of United States TIA-568-C.2 as well as requirements for fireproof performance of Underwriters' Laboratories of United States and have the advantages of convenience in use and arrangement.
