燙(tang)(tang)金(jin)(jin)工藝是(shi)(shi)利(li)用(yong)熱壓轉移的(de)(de)(de)原理，將電(dian)(dian)化鋁中的(de)(de)(de)鋁層(ceng)(ceng)(ceng)轉印到承印物表(biao)面以形成特殊(shu)的(de)(de)(de)金(jin)(jin)屬效(xiao)果(guo)，因燙(tang)(tang)金(jin)(jin)使用(yong)的(de)(de)(de)主要(yao)材(cai)料是(shi)(shi)電(dian)(dian)化鋁箔，因此(ci)燙(tang)(tang)金(jin)(jin)也叫電(dian)(dian)化鋁燙(tang)(tang)印。電(dian)(dian)化鋁箔通(tong)常由多(duo)層(ceng)(ceng)(ceng)材(cai)料構成，基材(cai)常為P E，其次是(shi)(shi)分離涂(tu)(tu)層(ceng)(ceng)(ceng)、顏色涂(tu)(tu)層(ceng)(ceng)(ceng)、金(jin)(jin)屬涂(tu)(tu)層(ceng)(ceng)(ceng)（鍍鋁）和膠水(shui)涂(tu)(tu)層(ceng)(ceng)(ceng)。
