燙金(jin)(jin)工藝是利(li)用(yong)熱壓轉移的(de)(de)原理，將電(dian)(dian)(dian)(dian)化鋁(lv)(lv)(lv)中的(de)(de)鋁(lv)(lv)(lv)層(ceng)(ceng)轉印(yin)(yin)到承(cheng)印(yin)(yin)物表面以形成特殊(shu)的(de)(de)金(jin)(jin)屬效果(guo)，因燙金(jin)(jin)使用(yong)的(de)(de)主(zhu)要材料(liao)是電(dian)(dian)(dian)(dian)化鋁(lv)(lv)(lv)箔，因此燙金(jin)(jin)也叫電(dian)(dian)(dian)(dian)化鋁(lv)(lv)(lv)燙印(yin)(yin)。電(dian)(dian)(dian)(dian)化鋁(lv)(lv)(lv)箔通(tong)常(chang)由多層(ceng)(ceng)材料(liao)構成，基材常(chang)為(wei)P E，其次是分離涂(tu)層(ceng)(ceng)、顏色(se)涂(tu)層(ceng)(ceng)、金(jin)(jin)屬涂(tu)層(ceng)(ceng)（鍍鋁(lv)(lv)(lv)）和膠水涂(tu)層(ceng)(ceng)。
