1. An anti-counterfeiting two-piece type electromagnetic induction sealing liner, comprising an adhesive layer, an electromagnetic induction heating layer, a weak adhesive layer, a backing layer and an information tag sequentially composited from bottom to top;
wherein, the information tag is built-in with an information chip and an antenna circuit electrically connected to the information chip; when the electromagnetic induction heating layer is heated, the weak adhesive layer is melted and absorbed by the backing layer, such that the electromagnetic induction heating layer is separated from the backing layer and the information tag.
