AI Technical Summary
The current double-sided tape products lack effective anti-counterfeiting identification methods, making it difficult to distinguish counterfeit products and affecting corporate image and brand value.
An anti-counterfeiting double-sided adhesive was designed, comprising a substrate layer, first and second anti-counterfeiting coatings, first and second adhesive layers, and a release layer. The coatings are located between the adhesive layer and the substrate layer. Anti-counterfeiting identification is achieved by a combination or composite of ink layer and fluorescent layer, thus building a technological barrier.
It achieves anti-counterfeiting identification of the tape itself, with strong concealment and is not easy to be counterfeited. It avoids the performance difference between the printed anti-counterfeiting area and the unprinted area, and meets the customization needs of different customers.
