XHG-015 is a uniquely designed button-type instrument seal. Its main material is polycarbonate (PC), which is renowned for its excellent impact resistance and transparency. The internal structure design of this seal is quite ingenious. The special feature lies in its internal locking mechanism, which is equipped with a unique toothed structure. This enables the seal to provide stronger tensile resistance when tensile force is applied. Once the seal is applied and fixed, it is almost impossible to pry it open, thus effectively preventing theft from happening. In addition, the XHG-015 seal also has a printable function, which can print the numbers on the domestic sales and the shell simultaneously to ensure the consistency of the information. Its shell design also allows for the printing of barcodes and QR codes, which provides great convenience for product tracking and management. Not only that, the printing area of XHG-015 is relatively large, which means it can accommodate more information and provide users with greater flexibility and convenience.
