[0001] This utility model relates to the field of lead seal label technology, and in particular to a passive container lead seal label with tamper-proof detection. Background Technology
[0002] Against the backdrop of rapid global trade development, container shipping, as a major logistics mode in international trade, undertakes a large number of cross-border transportation tasks. Container seals and tags, as key components to ensure the safety of cargo transportation, directly affect the safety and integrity of goods during transportation.
[0003] Existing lead seal labels have limited tamper-proof performance. Once illegally opened, they often leave no obvious and traceable traces, and it is difficult to accurately determine whether the seal has been tampered with afterward, posing a great threat to the security management of goods.
[0004] To address this, we propose a passive container seal label with tamper-proof detection capabilities. Summary of the Invention

An ABS high-strength plastic layer is fixedly disposed at the outer end of the acrylic polymer. An installation cavity is formed at the inner end of the acrylic polymer, and an RFID chip is fixedly installed inside the installation cavity. The acrylic polymer filling the seal tag, in conjunction with the outer ABS high-strength plastic layer, achieves the effect of a fragile inner layer and an impact-resistant outer layer. The RFID chip embedded inside the acrylic polymer enables a combination of physical tamper-proofing and electronic detection.
[0008] As a further embodiment of this utility model: an encapsulation substrate is fixedly installed on the outer end of the RFID chip, and the encapsulation substrate is located inside the mounting cavity. The RFID chip is used to store and transmit relevant information of the container, such as the seal number, cargo information, transportation route, etc., so that data can be collected and monitored by a reader during transportation.
[0009] As a further improvement of this utility model: an antenna is fixedly installed on one side of the packaging substrate. The antenna is located inside the mounting cavity. The antenna works in conjunction with the RFID chip to receive and transmit radio frequency signals, realize wireless communication with the reader, and enable the lead seal label to be identified and read from a distance.
[0010] As a further improvement of this utility model: a fixing block is fixedly installed at the top of the lead seal label body, a connecting block is fixedly installed on one side of the fixing block, and a sealing hole is opened at the inner end of the connecting block. The sealing hole extends through the inner end of the fixing block, which facilitates the accurate insertion position of the steel wire.
[0011] As a further improvement of this utility model: a steel wire is fixedly installed at the top of the connecting block, the steel wire is adapted to the sealing hole, the steel wire passes through the sealing hole, and cooperates with the sealing hole to facilitate the secure fixing of the lead seal label to the container.
[0012] As a further improvement of this utility model, a label information is fixedly provided on one side of the lead seal label body to facilitate the display of item information, such as the lead seal number, company name, production date, etc.
[0013] As a further improvement of this utility model, a barcode is fixedly provided on one side of the lead seal label body near the label information. The barcode contains detailed information about the container, which allows staff to quickly read and record relevant data through scanning equipment, thereby improving the efficiency and accuracy of logistics management.

The RFID chip embedded inside the acrylic polymer 2 can realize the combination of physical tamper-proof and electronic detection.
[0026] As shown in Figures 1-4, an encapsulation substrate 6 is fixedly mounted on the outer end of the RFID chip 5. The encapsulation substrate 6 is located inside the mounting cavity 4. An antenna 7 is fixedly mounted on one side of the encapsulation substrate 6, also located inside the mounting cavity 4. A fixing block 8 is fixedly mounted on the top of the lead-sealed tag body 1.
