Zusammenfassung: | The utility model belongs to the field of printing, packing and machinery, and particularly discloses a stereoimaging forgery prevention packaging product with positioning function. The utility model is characterized in that the packaging product adopts a composite layer structure and comprises a printing layer and a thin film layer from bottom to top, a printing structure region is arranged on the printing layer, and optical elements corresponding to the printing structure region are arranged on the upper surface of the thin film layer. As a mutual effect of the optical elements and the printing structure region, interferometric imaging occurs, which endows the packaging product with positioning and forgery prevention functions as well as 3-D visual effect. The utility model is applicable to various products with higher added value. |
