MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511123545 A) filed by Arpana Paliwal; Shiv Kumar Paliwal; and Siddharth Paliwal, Kanpur, Uttar Pradesh, on Dec. 8, 2025, for 'a method for producing a tamper-evident security seal with thermo-chromic and digital authentication features and a tamper-evident security seal for securing product packaging.'
Inventor(s) include Arpana Paliwal; Shiv Kumar Paliwal; and Siddharth Paliwal.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a tamper-evident security seal incorporating thermo-chromic and digital authentication features for securing product packaging. The invention further provides a method for producing such a seal, wherein a substrate material having defined 10 tackiness (about 925 N/m), coating weight (23-27 GSM), and adhesion power (460-480 N/m) is printed with thermochromic ink in dot patterns that change color at about 65 C to indicate heat-based tampering. Security cuts are formed on the substrate under a controlled pressure of 125-200 PSI to create localized weakened zones that tear irreversibly upon removal. A variable digital authentication feature comprising a QR code and a 1D barcode 15 encoded with alphanumeric data is printed on the seal to enable traceability and anti-counterfeiting verification. The resulting security seal provides multi-level protection through visual, mechanical, and digital indicators, making unauthorized removal, reuse, or counterfeiting readily detectable."
