Anti theft tag which led to a reversal of the great effect Barkhausen when subjected to a magnetic field, and merchandise having a label affixed in the same anti theft which generates an inversion of largeBarkhausen effect when subjected to a magnetic field

摘要

An antitheft label which generates a high Barkhausen inversion when subjected to a magnetic field. The antitheft label comprises a laminate of upper and lower tape bases each having an inner laminated surface and an outer surface, a first adhesive layer disposed on the inner surface of the upper tape base, a second adhesive layer disposed on the inner surface of said lower tape base, a pulse-generating magnetic wire and first and second magnetic thin ribbons disposed on opposite ends of the magnetic wire. The magnetic wire and magnetic thin ribbons are arranged between the upper and lower tape bases.
