 detailed description

 The invention will now be further described with reference to the drawings and embodiments.

 1 and 2 schematically show the shape and configuration of the fragile paper anti-counterfeit RFID tag of the first embodiment. As shown in Figure 1, the fragile paper is anti-counterfeiting. The RFID tag is a sheet-like label comprising a circular body 6 and a seal 7 extending outwardly from the edge of the circular body 6.

 Referring to Figure 2, the fragile paper anti-counterfeiting RFID tag includes an RFID tag layer 2, a fragile paper base temperature change security layer 1 and a release paper 3 . The substrate 21 of the RFID label layer 2 is made of ordinary fragile paper, and the RFID antenna 22 is printed on the front surface of the substrate 21, and the chip 23 and the RFID label layer 2 are packaged. For RFID functions, the center frequency can be designed for high frequencies (such as 13.56MHz) or ultra high frequencies (such as 910MHz). On the substrate 21 The back is coated with hot melt adhesive and covered with release paper 3. When used, it can be directly attached to the object after being detached from the release paper 3, which is very convenient to use.

 The substrate 21 of the RFID tag layer 2 includes a circular first body portion 211, and a first body portion 211 The edge has an outwardly extending first seal portion 212, the RFID antenna 22 and the chip 23 are disposed on the front side of the first body portion 211, and a portion of the RFID antenna 22 extends to the first seal portion 212. The base material of the fragile paper base temperature-changing security layer 1 has the same shape as the base material 21 of the RFID label layer 2, and includes a circular second main body portion 111 and a second main body portion 111. The second seal portion 112 extends outwardly from the rim. The shape of the release paper 3 is also the same as that of the RFID label layer 2 substrate 21.

 Fragile paper base temperature change security layer 1 composited on the RFID label layer by hot melt adhesive on the back of its substrate (fragile paper) 2 On the front side, the fragile paper base temperature change security layer 1 is made of temperature-changing fragile paper containing a temperature-changing material, and is therefore referred to as a hybrid temperature-changeable fragile paper layer. The temperature change threshold of the temperature change material is 85 °C, such as temperature change. Ink, the color can change from white to black. When the temperature reaches 85 °C, the temperature change security layer 1 The color will change from white to black, and the temperature will not return to white after the temperature is lowered. Therefore, when the counterfeiter attempts to transfer the fragile anti-counterfeit RFID tag on the object by heating, the temperature-changing security layer 1 The color automatically changes from white to black, so consumers can easily identify the authenticity of the item through the fragile paper anti-counterfeit RFID tag.

 Wherein, the temperature change threshold of the temperature change material is required to be less than or equal to the hot melt adhesive on the back surface of the substrate 21 (or the RFID label layer 2 Melting point of the hot melt on the back) The lower limit temperature of the temperature. If a temperature change material with a temperature change threshold of 85 °C is selected, the hot melt adhesive should have a melting point of 85 °C - 100 °C. Someone wants to add from the product When the RFID label is removed, the temperature reaches the lower limit of the melting point of the hot melt adhesive. The lower limit of temperature is 85 °C. The temperature change material changes color immediately. The temperature of the fragile paper is changed to the security layer. The color of at least part of the area changes irreversibly, avoiding illegal heat transfer of the label for reuse. For the hot melt adhesive (melting temperature 85 °C - 100 ° C) It is also feasible to select a temperature change material with a temperature change threshold of 75 ° C or 80 ° C.

 Understandably, the temperature change material can select other temperature change materials of temperature change threshold and color, and generally select irreversible temperature change ink or irreversible temperature change color powder, The choice of color is best such that the color difference before and after the change is large.

 Further, it is also possible to form a temperature-sensitive anti-counterfeit layer on the fragile paper base 1 The temperature-changing fragile paper is printed on a pattern, which can be any image, text, number, trademark, etc., to better prevent counterfeiting.
