燙(tang)(tang)金(jin)(jin)工藝是(shi)利用(yong)熱(re)壓轉(zhuan)(zhuan)移的原理，將電(dian)(dian)化鋁(lv)(lv)中(zhong)的鋁(lv)(lv)層(ceng)(ceng)轉(zhuan)(zhuan)印(yin)(yin)到(dao)承(cheng)印(yin)(yin)物表(biao)面以形(xing)成特殊的金(jin)(jin)屬效(xiao)果，因燙(tang)(tang)金(jin)(jin)使用(yong)的主要材(cai)料是(shi)電(dian)(dian)化鋁(lv)(lv)箔，因此燙(tang)(tang)金(jin)(jin)也(ye)叫電(dian)(dian)化鋁(lv)(lv)燙(tang)(tang)印(yin)(yin)。電(dian)(dian)化鋁(lv)(lv)箔通常由多(duo)層(ceng)(ceng)材(cai)料構成，基(ji)材(cai)常為(wei)P E，其次是(shi)分離涂(tu)層(ceng)(ceng)、顏色涂(tu)層(ceng)(ceng)、金(jin)(jin)屬涂(tu)層(ceng)(ceng)（鍍(du)鋁(lv)(lv)）和膠水涂(tu)層(ceng)(ceng)。
