ABSTRACT:
An antitheft label composed of a soft magnetic metal strip permanently applied to an electroconductive nonmagnetic metal member. The label is attached to an object to prevent the object from being stolen or taken without permission. An object, such as food goods, having such an antitheft label can be thawed or heated in a high-frequency heater such as a microwave oven without developing spark discharge at edges of the soft magnetic metal strip of the label, thereby preventing the occurrence of fire damage to the food product.
