The application advantage of conductive ink in RFID label printing

RFID label, as a kind of smart label, is being paid attention to by more and more users and label manufacturers. However, this kind of label is different from the full digital 3-bi-loop control software spring experimental machine developed by our company for 5 years. The production of this kind of label can be completely completed by printing, To use printing technology to complete the printing process of RFID tags, only new conductive ink can be used

the conductive ink used for RFID tags is composed of fine conductive particles or other special materials (such as conductive polymers, etc.). When printed on the bearing, the friction force between the pendulum bearings will be generated. After printed on the print, it plays the role of wire, antenna and resistance. This kind of ink can be printed on a flexible or hard substrate to make a printed circuit, and the antenna printed with conductive ink can receive radio signals dedicated to RFID. Nowadays, using conductive ink to make RFID tag antenna in high-speed printing has outstanding advantages

1. excellent conductive effect

as we all know, smart tags are new types of tags with more powerful functions than traditional data tags, including RFID tags, explicit/implicit anti-counterfeiting tags and sensor tags with indication of product status. In RFID tags, conductive ink can be used to connect the components of the tag and act as a sensor or antenna

2. Reduce costs

in the promotion of RFID tags, the biggest problem is the cost. The price of each RFID tag is US $0.3-0.6. For those high-end products, an increase of $0.50 can be accepted by manufacturers and consumers, because for them, RFID tag is an excellent identification and tracking device, which brings convenience and benefits more cost-effective. However, for medium. For low-end consumer goods, RFID tags are not easy to accept. After all, no one can accept an ordinary toothpaste that has increased by $0.50 because of the use of RFID tags

conductive ink saves the cost of RFID tags from two aspects. First of all, in terms of material cost, the price of ink is lower than that of stamping or etching metal coils; Secondly, in terms of material consumption, stamping or etching consumes a lot of metal, while conductive ink printing antenna or circuit has high speed, low cost and high efficiency

in the past, conductive ink was printed only with silk. Now, it has been extended to offset printing, flexographic printing and gravure printing. Flint inks and r.t.circuits have signed an exclusive license to use conductive inks in offset printing. This is an important technological progress, which has promoted the production and use of RFID tags. In particular, large retailers can require suppliers to provide goods with RFID tags

for manufacturers, retailers and consumers, smart tags provide a real-time and visible product catalog, which can help users master the status of goods and every link of the supply chain

the prospect of RFID tags

the global RFID tag market reached US $4billion in 2004 and is expected to exceed US $7billion in 2006. At the RFID symposium held in Shanghai, experts predicted that the global RFID market would reach $300billion in 2010. Although the results predicted by different institutions are different, they all depict the application prospect of RFID tags

with the full opening of the commodity market, the process of comprehensively promoting and applying RFID tags in China has been accelerated. In the future, China will need more than 3billion electronic labels, of which 83million will be needed for consumer electronics; Cigarette products need 800million pieces; alcohol products need 130million pieces; It products need 1.3 billion to 1.4 billion pieces, and other products need about 700million pieces

China has started relevant technology research and development and standard formulation. In February, 2004, the national standard working group on electronic labels was announced to be established. They are responsible for drafting and formulating China's national standards on electronic labels in the process of the coordinated development of enterprises and regions. At the end of April, Chinese enterprises have joined the RFID global standards organization EPC global and established EPC Global China at the same time
