The birth date of nano-anti-wipe technology will not be altered

In recent developments, Hohhot and Lingle Economic Development Zones in Inner Mongolia have successfully introduced nano-anti-wiping technology, marking a significant step toward its practical application. This innovative method allows for the printing of product information—such as manufacturing dates and origins—onto packaging in a way that makes these codes nearly impossible to alter or erase. These "tamper-proof" codes are now being used on various products, offering a new level of security and transparency. During a demonstration at the Helinger Economic Development Zone, Professor Li Hong from the Hong Kong Polytechnic University, the inventor of the nano-anti-wiping technology, showed reporters how it works. Two identical milk packages were presented: one with standard inkjet-printed date labels, and the other with the new nano-technology applied. When tested with acetone and other organic solvents, the regular label was easily wiped away, while the nano-treated label remained completely intact, no matter the reagent used. Professor Li explained that traditional printing methods on food packaging often leave room for manipulation. Unscrupulous sellers can alter expiration dates after products have passed their shelf life, posing serious risks to consumer safety. The nano-anti-wiping technology addresses this long-standing issue, providing a reliable solution for industries such as food, pharmaceuticals, and fast-moving consumer goods. It not only helps protect consumers but also supports fair market practices and prevents the circulation of counterfeit or tampered products. With this breakthrough, the technology is expected to play a crucial role in enhancing product traceability and ensuring greater trust in the marketplace.
