RFID packaging container for reducing interference of sealing metal foil

Abstract

The invention discloses an RFID packaging container for reducing the interference of sealing metal foil. The RFID packaging container comprises a bottle cap and a bottle body. An RFID inlay is implanted in the bottle cap. A sealing film is arranged on the bottle body and is a high-water-stop plastic film. The high-water-stop plastic film is one of or the combinations of more of an aluminum oxide plastic film, a silicon oxide plastic film, a silicon nitride plastic film and a PVDC plastic film. An RFID is hidden in the bottle cap, the RFID packaging container has an unreplicable globally-uniqueidentifier, has a tracing function and a group reading function, can be identified without being unboxed, can allow data to be written therein, and has a communication function. Sealing is realized without traditional metal foil, the interference of the metal foil at a bottle mouth on the reflecting, shielding or capacitance effect or the like of an RFID antenna can be avoided, and the moisture insulation capacity like that of traditional aluminum foil can still be maintained. Tracing can be started when the bottle cap is completed, not only can drug production be traced, but also the container can be traced, and the quality guarantee to consumers is the most complete.

Description

technical field [0001] The invention relates to an RFID packaging container which improves the interference of sealing metal foil, and belongs to the technical field of electronic labels. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification. The RFID antenna is composed of a conductor circuit as the medium for RFID signal and energy transmission. The most mainstream structure is PET and the aluminum foil circuit on it. RFID inlay refers to a component with a complete electronic function after a layer of anisotropic conductive adhesive is arranged between the chip and the RFID antenna, and it is bonded with high temperature and high pressure. It includes a PET substrate, an aluminum foil antenna Circuits, chips and conductive glue. [0003] The known packaging plastic containers for food, pharmaceuticals, cosmetics, cleaning products, nutritional products, health products, and skin care products use the following identification methods: A....

AI Technical Summary

Problems solved by technology

[0004] Identification method A, barcode or QR code can be identified for identification, but there are the following problems: 1. It is easy to be decoded, copied and forged, 2. The label can only read the code and cannot continuously record data, 3. The scanner must be correct for identification It is time-consuming and labor-intensive to read quasi-barcodes one by one. 4. The barcode is marked or pasted after the product has completed the manufacturing process and packaged. It is difficult to trace back the data history in production

[0005] Identification method B, adding an RFID label, although this method has improved the above-mentioned shortcomings of the barcode, there are still the following problems: 1. The label is easily removed by heating and repeatedly pasted on the counterfeit product; 2. The concealment of the label is not good; 3. The label is only attached to its container after the product manufacturing process and packaging are completed, and its traceability depth is still insufficient for the problems that it is difficult to trace back the data history in production, etc.

[0006] Identification method C is to inject RFID into the plastic of the bottle cap. Although this is a great improvement, most bottle seals use metal foil (mainly aluminum foil), because the distance between the metal foil and the injected RFID antenna is too close And heavy, it has reflection, shielding and capacitive effects on the RFID electromagnetic wave signal, which makes it difficult to read and write smoothly on the bottle body of this kind of combination RFID bottle cap, and the effective reading distance is reduced to a very small
