Description

A linerless RFID label based on etched antenna

technical field

The utility model relates to the technical field of labels, in particular to a bottomless RFID label based on an etching antenna.

Background technique

According to statistics, my country's self-adhesive label market is currently about 450-500 million square meters, while the per capita annual consumption of self-adhesive labels in developed countries is 8-12 square meters, of which Australia's per capita consumption reaches 12 square meters per person /year, it can be seen that my country's self-adhesive label market has great potential. However, the most widely used self-adhesive labels currently on the market in my country are composed of face paper, adhesives and backing paper. Paper is also not easy to recycle. In addition, since the backing paper is a part of the traditional label, it needs to occupy a certain amount of space and weight during transportation, which virtually increases the transportation cost of the traditional self-adhesive label. Labels are closely related to people's daily life, and barcode labels have entered every corner of our lives. Almost all commodities need to use barcode labels. The identification of traditional barcode labels needs to work under the guidance of people, and can only receive barcodes within the scanner's field of view. Barcode labels can only identify producers and products, and cannot identify specific commodities. They are pasted on all the same product packaging. The barcodes are the same, traditional barcode labels cannot meet people's growing technical needs in the fields of commodity production, management and circulation. In today's society where high intelligence is developing rapidly, RFID technology is an effective means of intelligent management, and its application scope has involved commodity production, storage and transportation management. However, the cost of RFID tags is much higher than that of barcodes, which limits the popularization and application of RFID tags. How to reduce the cost of RFID tags has become a problem we face. Combining linerless label technology with radio frequency identification technology, the development of linerless RFID labels that do not use liner materials, have flexible recognition distances, large amounts of information, and low manufacturing costs will become an important development direction of the label market.

Contents of the invention

The purpose of this utility model is to solve the problems of the existing barcode label bottom paper, such as serious waste, small data capacity, and inability to identify specific commodities, etc., and provide a bottomless paper based on etching antennas that can be used in various links such as commodity production, circulation, and management. RFID tags.

In order to achieve the above object, the utility model adopts the following technical solutions:

A bottomless RFID label based on an etched antenna, including a silicone oil layer, an anti-seepage coating, a surface layer, an RFID label layer composed of an etched antenna and an RFID chip, which are arranged in sequence from top to bottom and pasted or coated as one , a base layer, and an adhesive layer, wherein the silicone oil layer is located on the upper surface of the linerless RFID label, the adhesive layer is located on the lower surface of the linerless RFID label, and a tear line is processed between every two adjacent labels.

The base layer is an insulating base material composed of PET film or coated paper. The base layer is used for fixing and encapsulating the RFID label layer, and at the same time as the carrier of the adhesive layer.

The RFID tag layer is composed of an etched antenna and an RFID chip connected by conductive glue. The production method of etching antenna is as follows. First, attach a layer of copper or aluminum foil to the insulator base (PET or PP film), and then use screen printing to cover a layer of anti-corrosion ink on the part that does not need to be etched. After etching, there is no protection. Part of the layer becomes the gap between the antenna coils, and finally the anti-corrosion ink is washed away to form an etched antenna.

The surface layer is thermal paper. As the outer material of the bottomless RFID label, the thermal paper layer is not only used for the encapsulation of the RFID label layer, encapsulating the RFID label between the surface layer and the base layer, but also for printing some label information.

The anti-seepage coating is composed of polyvinyl alcohol 5%-10%, starch 0.5%-2%, styrene-butadiene latex 5%-10%, styrene-acrylic emulsion 0.4%-2%, water-based oil repellent 0.8%-3% , and the remaining distilled water is configured according to the mass percentage. The anti-seepage coating is one of the important technical innovation points of the utility model. The anti-seepage coating plays the purpose of preventing the penetration of silicone oil. Since the coating amount of the silicone oil layer is only 1-2g/㎡, if there is no anti-seepage coating, Excessive penetration of silicone oil will increase the coating amount of silicone oil and increase the cost, and too much silicone oil will lead to uneven distribution of silicone oil, and the penetration of silicone oil will also affect the quality of the label.

The silicone oil layer is water-based silicone oil or UV curable silicone oil, and the application amount is 1g/㎡-2g/㎡. The utility model creatively coats a layer of silicone oil layer on the anti-seepage coating layer, which is the technical innovation of the utility model. When the label is rolled, the glue layer on the lower surface of the label covers the outer surface of the rolled label. On top of the silicone oil layer, a uniform and stable silicone oil layer can ensure that the label can be quickly separated from the label roll when in use. This ingenious design saves the necessary backing paper for the label and greatly saves raw materials. costs and process costs.

The adhesive layer is self-adhesive or pressure-sensitive adhesive, and the amount of adhesive is 8 g/㎡-30 g/㎡. The adhesive layer is used to stick the label to the product when the label is used.

The beneficial effects of the utility model are:

(1) The utility model provides a bottomless RFID label based on an etched antenna, which saves the bottom paper of the traditional label, avoids the waste of the bottom paper, and significantly saves the cost of raw materials.

(2) The bottomless RFID label based on the etched antenna provided by the utility model can effectively prevent the diffusion of silicone oil to the surface due to the research and development of a special anti-seepage coating for silicone oil, which is conducive to improving the stability of the label quality.

(3) The utility model provides a bottomless RFID label based on an etched antenna, which combines the bottomless technology of the label with the radio frequency identification technology to develop a brand new bottomless RFID label. The saving of paper raw material cost and process cost reduces the production cost of linerless RFID tags, which is conducive to the promotion and use of linerless RFID tags.
