A preparation method of an RFID tag embedded in a packaging substrate by hot stamping

Abstract

The invention provides an RFID tag arranged in a packaging base material in a gold stamping manner. The RFID tag at least comprises a PET substrate, an antenna metal layer and a chip. A stripping layer and a composite glue layer are sequentially arranged on the upper surface of the PET substrate; the antenna metal layer is fixedly arranged on the upper surface of the composite glue layer; the chip is attached to the antenna metal layer through a conductive adhesive; a pressure-sensitive adhesive layer or a hot melt adhesive layer are arranged on the antenna metal layer; and a release paper is arranged on the upper surface of the pressure-sensitive adhesive layer. The invention also provides a preparation and arrangement process of the RFID tag. The defects in the prior art are solved; the RFID tag can be directly arranged in the paper or film base materials of a packing box without influencing production efficiency of an original product; and meanwhile, the RFID tag has an anti-peel-off capacity (the tag is disposable to prevent peel off), and is green and environmentally friendly.

Description

technical field [0001] The invention provides an RFID label inserted into a packaging base material by hot stamping and a production process thereof, belonging to the technical field of RFID electronic label production, processing and application process. Background technique [0002] Electronic tags are RFID (Radio Frequency IDentification) technology. Electronic tags are also called radio frequency tags, transponders, data carriers, or radio frequency identification. It is a wireless communication technology that can identify specific targets and read and write related data through radio signals. The basic components of the system include RFID electronic tags, RFID readers and antennas, among which, the antenna is a device that receives or radiates the radio frequency signal power of the radio transceiver in the form of electromagnetic waves. RFID working principle: After the tag enters the magnetic field, it receives the radio frequency signal sent by the reader, and send...

AI Technical Summary

Problems solved by technology

Because the traditional RFID label has a thicker PET antenna substrate layer, it has no anti-tear ability, and it is easy to be re-labeled and then posted on other items, thus losing the basic uses of RFID labels such as anti-counterfeiting and traceability.

[0005] 2. At the same time, RFID labels need to be pasted on the packaging materials during use, which requires additional labeling links in the printing or packaging process. Since the labeling speed is slow, it will slow down the production efficiency of the original product

[0006] 3. The glue used for labeling is usually solvent-based glue, which has certain toxicity and is difficult to pass the VOCS test.
