More and more packaging cartons adopt hot stamping process

in the fierce market competition, in order to increase the added value of products and more effectively carry out packaging anti-counterfeiting, more and more packaging cartons adopt hot stamping process. Hot stamping is divided into ordinary hot stamping, cold hot stamping, as well as magnetite concave convex hot stamping and holographic hot stamping in Brazil, Chile, Finland and other places with potential supply capacity. Common hot stamping processes include flat hot stamping and circular hot stamping. Circular hot stamping is a line contact method, which has the characteristics of wide hot stamping substrates, suitable for large-area hot stamping and high hot stamping precision

hot stamping does not require heated metal plates, but uses printing adhesives to transfer metal foil. Cold hot stamping process is a promising new process with low cost, energy saving and high production efficiency

concave convex hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make the upper and lower matching female and male molds. The hot stamping and embossing processes are completed at one time, which improves the production efficiency. The molds made by electric engraving can achieve the three-dimensional relief effect that can not be achieved by the molds made by general corrosion method through surface transition. With the appearance of concave convex hot stamping, the hot stamping and embossing processes are completed at the same time, reducing the process and waste products caused by inaccurate overprint

holographic identification hot stamping uses computer technology to change the amplitude and frequency of the grating, making its effect more brilliant and clear than the calculated pattern color. If the hologram mark is used as the copy of the original, a large number of holograms will be lost, which can achieve the purpose of anti-counterfeiting. Holographic identification can not only have very good anti-counterfeiting performance, but also can make special numbers or words into holographic identification according to the prosperous needs of the customer market. The more widely it is used in high-end carton packaging. At present, the measurement and control system of most tensile machines in the market is controlled by an 8-bit single-chip computer
