AI Technical Summary
The existing invisible ultraviolet variable anti-counterfeiting label has an unreasonable structural design, lacks waterproof function at the adhesive joint, is easy to fall off, and has poor anti-counterfeiting effect, making it easy to be counterfeited.
A multi-layer structure was designed, comprising a label base layer, a transparent positioning layer, a transparent abrasion-resistant surface layer, a covering layer, a fragile paper layer, an adhesive layer, and a waterproof strip. The adhesive layer is used to seal and fix the label to the outer surface of the product. Combined with multiple anti-counterfeiting graphics and a UV-sensitive color-changing coating, the waterproof performance and anti-counterfeiting effect are enhanced.
The label features excellent waterproof performance at the adhesive joint, making it less prone to falling off. Furthermore, its multiple anti-counterfeiting structures enhance its anti-counterfeiting effectiveness, making it difficult to counterfeit and improving its practicality.
