烫金工艺是利用热压转移的原理，将电化铝中的铝层转印到承印物表面以形成特殊的金属效果，因烫金使用的主要材料是电化铝箔，因此烫金也叫电化铝烫印。

电化铝箔通常由多层材料构成，基材常为P E，其次是分离涂层、颜色涂层、金属涂层（镀铝）和胶水涂层。

而印刷行业中常用的是将电化铝箔烫印在纸类上，称之为烫金，烫金是一种工艺的统称。烫金并不是指烫上去的就是金色。烫金纸材料分很多种，其中有金色的、银色、镭射金、镭射银、黑色、红色、绿色等等多种多样。

Hot stamping process is the use of heat and pressure transfer principle, the aluminum layer in the electrochemical aluminum transfer to the substrate surface to form a special metal effect, because the main material used in hot stamping is electrochemical aluminum foil, so hot stamping is also known as electrochemical aluminum stamping.

Electrochemical aluminum foil is usually composed of multiple layers of materials, the substrate is often P E, followed by separation coating, color coating, metal coating (aluminum) and glue coating.

And the printing industry is commonly used to electrochemical aluminum foil hot stamping on paper, known as bronzing, bronzing is a process collectively.Hot stamping does not mean that the hot is gold.Bronzing paper materials are divided into many kinds, including gold, silver, laser gold, laser silver, black, red, green and so on a variety of.
