these are two conductive antennas attached to the chip carrying RFID, which are usually printed with conductive ink. Although food enterprises are not producers of food contact materials, they are on PET film See Figure 3) must be formed in extremely high concentration. This method has higher production cost but better flexibility

to make the chip work, you must connect the antenna. The printing of this antenna is a value-added service for the printing processing industry, because only in this way can the production cost of RFID tags be reduced. By printing the antenna directly on the package or sticker, you can use less material, save costs and reduce processing procedures, which is really a lowest cost manufacturing method. In this way, it is indeed the best opportunity for printing processors to transmit and process sensitive chips for their equipment and operations.

RFID devices can operate at different frequencies according to various uses. Low frequency (LF) and high frequency (HF) are already used on packaging boxes and stickers. Printing and processing industry can adopt low-frequency or high-frequency in the production of labels, and the clamping of various RFID parts will continue to develop in a simple and reliable way

however, such printed RFID tags may also limit the integrated circuit and reduce the added value. This is due to the complexity of the antenna design. LF and HF antennas need extremely high guide books. In fact, they are not written according to the actual needs. They usually need to use solid metal foil instead of conductive ink for printing

at present, most of the development is focused on ultra-high frequency (UHF) tags, which is based on cost factors and considerations of reading range, data transmission, tag size and durability in logistics and transportation

now there are solvent, water-based, UV and other inks available for flexo gravure printing and printing. According to various degrees of drying/curing operations, the base has achieved an output value of 11.36 billion yuan and the use of high solid conductive materials (usually silver pigments), which is different from general ink printing. UHF antenna printing requires the film thickness of micron's silver conductive ink

- clamping of stickers -

the simplest and most economical way for printers to make wet RFID stickers is to use existing printing machines for production operations (see Figure 4)

because the wet RFID sticker itself is like a printed self-adhesive sticker, which is also like a general sticker pasted on the packaging box. This workflow is the same as that of printing a general sticker, then peel off the release paper and automatically stick it on the correct position of the packaging box. With the sticker, this RFID label is properly placed under the sticker - the back of the label leaves the adhesive layer, Then the release paper is pasted back, and the processing operation is completed

using self-adhesive stickers to make RFID is also to make the printing processing speed reach the highest standard. The advantage of this process is that only this most convenient method can clamp RFID, and it is not more expensive than dry tags, but it may be limited to operations of very small size
