Radio frequency identification tag and manufacturing method thereof

Abstract

The invention discloses a radio frequency identification tag and a manufacturing method thereof. The radio frequency identification tag comprises a face layer, a thermal contraction layer, a release layer, a fragile radio frequency identification layer and an adhesive layer, wherein the face layer, the thermal contraction layer, the release layer, the fragile radio frequency identification layer and the adhesive layer are sequentially and mutually composite. The thermal contraction layer is made of thermal contraction polyvinylchloride, thermal contraction polyethylene glycol terephthalate, thermal contraction polyethylene, multi-layer coextrusion polyolefin, directional polystyrene, thermal contraction polypropylene or thermal contraction biaxially oriented polypropylene. Due to the thermal contraction layer, the radio frequency identification tag can be prevented from being recycled again; due to the release layer contained in the tag, when the tag is torn off, the fragile radio frequency identification layer can be separated from the face layer and the contraction layer and is left on the surface of an adherend, integrity of the tag is broken and the effect of preventing the tag from being recycled is achieved.

Description

technical field [0001] The invention relates to a radio frequency identification electronic tag and a preparation method thereof Background technique [0002] Radio frequency identification (RFID for short) technology automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual interference and can work in various environments. It can identify multiple tags at the same time, and the operation is fast and convenient. After 2004, RFID technology has developed vigorously, and has wide application potential in the fields of warehousing and logistics, product anti-counterfeiting, product circulation, and product maintenance and tracking. In the application of product anti-counterfeiting, RFID is called a new generation of "electronic patron saint" because of its safety, efficiency, speed, large storage capacity, and free change of stored information. [0003] At the same time, because the UID c...

Problems solved by technology

[0004] At present, most of the RFID tags on the market use paper or polyester film as the base material for production, especially the aluminum etching RFID tags that are widely used at present. In view of the limitations of its aluminum etching process and chip binding process, the prepared RFID tags It is tightly bonded to the substrate, which provides good processing and use stability, but it also limits its application in the field of commodity circulation, especially in the field of commodity anti-counterfeiting

Criminals can use certain physical and chemical means to completely peel off the RFID tag on the genuine product without destroying its physical structure, and the tag can still be read. If it is pasted on the counterfeit product, it will be difficult to distinguish it from the genuine product. Lost its significance as anti-counterfeiting and logistics management

In particular, some counterfeiters soften the label adhesive layer (usually a pressure-sensitive adhesive) by means of heating, such as using a hair dryer for hot air heating, and reduce the adhesive strength of the adhesive before peeling off the label. Recycling and reuse has become a relatively common means of counterfeiting, which has brought a certain impact on the application of normal anti-counterfeiting and anti-counterfeiting technologies
