Thermal pad printing technology, commonly known as bronzing, hot stamping, and the scientific name is electrochemical aluminum hot stamping, is a special printing process that does not require ink. It uses a certain pressure and temperature to use a template installed on a hot stamping machine. The printed matter and the hot stamping foil are pressed against each other in a short period of time, and the metal foil or pigment foil is transferred to the surface of the printed matter according to the image and text of the hot stamping template.

In recent years, as people's requirements for the appearance and quality of product packaging have increased, printing technology and packaging technology have made great progress, and post-press processing technology has achieved vigorous development, and As a part of post-press processing, electrochemical aluminum hot stamping has changed even more dramatically in recent years. The continuous emergence of new technologies, new processes and the combined use of multiple technologies has enabled packaging printed matter to achieve better results in terms of gloss, three-dimensionality, metallic feel and anti-counterfeiting performance after hot stamping, especially as the current applications are becoming more and more popular. Extensive three-dimensional hot stamping technology makes the packaging of goods look high-end, exquisite, magnificent and full of personality. At present, this technology is mainly used in greeting cards, bookmarks, trademarks, tobacco and alcohol packaging and various high-end packaging boxes.
