Radio Frequency Identification (RFID), radio Frequency Identification, also known as radio frequency identification, is a wireless communication technology that can identify a specific object by radio signals and read and write related data without establishing mechanical or optical contact between the identification system and the specific object. The existing RFID tag is mainly used on a plastic bottle attached object made of PP or HDPE materials and mainly adopts the following product structure, namely a surface material, a glue material, a dry adhesive material and an attached object. An antenna and a chip are packaged by copper paper or other materials, and the antenna and the chip are divided into two types, namely a dry antenna and a wet antenna. The dry ink is a non-adhesive, and the wet ink is a layer of non-adhesive, and the ink can be directly used as a finished product. The material cost of the structure of the surface material, the adhesive material, the dry adhesive material and the adhered object is high, and the adhesive force between the RFID tag and the adhered object of the PP or HDPE plastic bottle is insufficient, so that the RFID tag is easy to tear.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides an RFID label and a pasting method thereof, simplifies the product structure, improves the adhesive force between a dry label and a pasted object, and solves the problem that the RFID label is easy to tear from the pasted object due to insufficient adhesive force of adhesive materials.
In order to solve the technical problems, the invention provides an RFID tag, which comprises a dry ink, wherein the surface of the dry ink is coated with a polyolefin medium, and the polyolefin medium contains polyolefin with a mass ratio of 12-55%.
Preferably, the main component of the polyolefin-based medium is polypropylene, and further comprises one or more of propylene copolymer, poly-1-butene, poly-4-methyl-1-pentene, and cycloolefin polymer.
Preferably, the dry antenna comprises a PET substrate, an antenna, ACP conductive adhesive and a chip from bottom to top.
The invention also provides a method for sticking the RFID label, which is to stick the dry lay coated with the polyolefin medium on an object to be stuck, and weld the dry lay and the object to be stuck to form by utilizing ultrasonic waves.
Preferably, the wavelength of the ultrasonic wave is 0.005-0.017 m.
Preferably, the ultrasonic wave generating device is an ultrasonic wave generator.
Preferably, the welding power is 2.5-10 KW, the frequency is 25-60 KHz, and the time is 0.1-1 sec.
Preferably, the object is a plastic bottle made of PP or HDPE.
The invention has the beneficial effects that:
1. the invention uses the energy released by ultrasonic wave with specific wavelength to weld and shape the dry lay coated with polyolefin medium and the object to be pasted, thereby improving the adhesive force of the dry lay and the object to be pasted and preventing the dry lay from being torn and counterfeited.
2. Compared with the prior art, the invention simplifies the product structure and shortens the process flow; the product structure reduces the surface material and a layer of glue material, and reduces the material cost; the end customer can conveniently post various color labels on the labels.
