燙(tang)(tang)(tang)金工藝是利用熱壓轉移的原理(li)，將(jiang)電(dian)(dian)化(hua)鋁(lv)(lv)(lv)(lv)中(zhong)的鋁(lv)(lv)(lv)(lv)層(ceng)(ceng)(ceng)轉印到承印物表面以形(xing)成特殊的金屬效果(guo)，因(yin)燙(tang)(tang)(tang)金使用的主要材料是電(dian)(dian)化(hua)鋁(lv)(lv)(lv)(lv)箔，因(yin)此燙(tang)(tang)(tang)金也叫電(dian)(dian)化(hua)鋁(lv)(lv)(lv)(lv)燙(tang)(tang)(tang)印。電(dian)(dian)化(hua)鋁(lv)(lv)(lv)(lv)箔通常(chang)由多層(ceng)(ceng)(ceng)材料構成，基材常(chang)為P E，其(qi)次是分離涂(tu)(tu)層(ceng)(ceng)(ceng)、顏色涂(tu)(tu)層(ceng)(ceng)(ceng)、金屬涂(tu)(tu)層(ceng)(ceng)(ceng)（鍍(du)鋁(lv)(lv)(lv)(lv)）和(he)膠水涂(tu)(tu)層(ceng)(ceng)(ceng)。
