[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 2 A high-strength hot stamping foil in this embodiment includes a base film layer 1, a hot melt adhesive layer 2, an aluminum layer 3, a pigment layer 4, and a protective layer 5 stacked sequentially. The base film layer 1 is a modified polyester film, and the surface of the aluminum layer 3 is provided with a microporous structure 30. The pigment layer 4 is composed of nano-pigment particles, and the protective layer is a modified polyurethane coating.

[0016] Furthermore, the microporous structure 30 is circular, square, or triangular in shape; the microporous structure design not only increases the bonding force between the aluminum layer and the pigment layer, but also gives the hot stamping foil a unique optical effect.

[0017] Furthermore, the surface of the protective layer 5 is also coated with a nano-ceramic coating 6. The modified polyurethane coating and the nano-ceramic coating 6 have excellent chemical corrosion resistance, effectively resisting the erosion of external chemicals and protecting the hot stamping pattern from damage.

[0018] Furthermore, the materials used for the nano-pigment particles are nano-titanium dioxide, nano-iron oxide, or nano-zinc oxide. These nano-pigment particles possess excellent optical properties, enabling more vibrant colors and higher gloss, while also exhibiting good weather resistance and UV resistance.

[0019] Furthermore, nano-silica particles are added to the hot melt adhesive layer 2. The addition of nano-silica particles improves the heat resistance of the hot melt adhesive, ensuring that the hot stamping foil can work stably under high temperature conditions.

[0020] Furthermore, the base film layer 1 contains glass fibers and nano-alumina particles.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
