燙金(jin)(jin)(jin)(jin)工(gong)藝是(shi)利用熱壓(ya)轉(zhuan)移(yi)的原(yuan)理，將電(dian)化鋁(lv)(lv)中的鋁(lv)(lv)層(ceng)(ceng)轉(zhuan)印到承印物表面以形成(cheng)(cheng)特殊的金(jin)(jin)(jin)(jin)屬(shu)效果(guo)，因燙金(jin)(jin)(jin)(jin)使用的主(zhu)要材(cai)料是(shi)電(dian)化鋁(lv)(lv)箔，因此燙金(jin)(jin)(jin)(jin)也叫電(dian)化鋁(lv)(lv)燙印。電(dian)化鋁(lv)(lv)箔通常(chang)由(you)多層(ceng)(ceng)材(cai)料構成(cheng)(cheng)，基材(cai)常(chang)為P E，其次是(shi)分(fen)離涂(tu)(tu)(tu)層(ceng)(ceng)、顏色涂(tu)(tu)(tu)層(ceng)(ceng)、金(jin)(jin)(jin)(jin)屬(shu)涂(tu)(tu)(tu)層(ceng)(ceng)（鍍鋁(lv)(lv)）和膠水(shui)涂(tu)(tu)(tu)層(ceng)(ceng)。
