Bottomless paper RFID label based on conductive ink printed antenna

Abstract

The present invention relates to a bottomless paper RFID label based on a conductive ink printed antenna, and to the label technology field. The label comprises a parting agent coating, an impermeable layer, a thermal paper layer, a RFID label layer, a bottom layer, a gluing layer and a tearing wire, wherein the RFID label layer is bound between the lower surface of the thermal paper layer and the upper surface of the bottom layer, the gluing layer is coated at the lower surface of the bottom layer, the impermeable layer is coated at the upper surface of the thermal paper layer, the parting agent coating is coated on the impermeable layer, the tearing wire is processed between adjacent labels. The bottom layer is insulation base materials. The RFID label layer is formed by connecting an antenna prepared by conductive ink printing and a RFID chip through the conductive adhesive. The impermeable layer is prepared through carboxylic butadiene-styrene latex, PVA, styrene-acrylic emulsion, perfluor carboxylic acid oil-proofing agent, starch and distilled water in proportion. The parting agent coating is silicone oil, and the gluing layer is adhesive sticker. The bottomless paper RFID label based on the conductive ink printed antenna saves the bottom papers and employs the conductive ink printed antenna so as to greatly reduce the cost of the RFID label and play an important effect on the promotion of the popularization and the application.

Description

technical field [0001] The invention relates to the technical field of labels, in particular to a bottomless RFID label based on a conductive ink printed antenna. Background technique [0002] According to statistics, in 2013, my country's self-adhesive label printing market size was 63.76 billion US dollars, and in 2014 it reached 67.95 billion US dollars. In the markets of developed countries in Europe and the United States, the per capita annual consumption of self-adhesive is 8-12 square meters, while the per capita annual consumption in my country is less than 1 square meter, which fully demonstrates that my country's self-adhesive label market has great room for development. However, the most widely used self-adhesive labels currently on the market in my country are composed of face paper, adhesives and backing paper. The backing paper is not easy to recycle; in addition, almost half of the thickness of traditional self-adhesive labels is taken up by the backing paper ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the serious waste of the existing self-adhesive label bottom paper and the traditional RFID label antenna production methods such as copper wire winding method, electroplating method, metal aluminum foil etching method and other methods. The cost of raw materials and equipment costs are very high. A series of production problems such as large production investment and long cycle, provide a bottomless RFID label based on conductive ink printed antenna that can be used in the fields of commodity production, logistics, and sales
