Metal label and preparation method thereof

The invention discloses a metal label and a preparation method thereof. The metal label sequentially comprises a metal substrate and a printing layer from bottom to top, wherein the metal substrate sequentially comprises a first metal foil and an aluminum foil from bottom to top, and the first metal foil is a tin foil or a lead foil. The metal label is advantaged in that the metal label is ingenious in design and low in production cost, special equipment and instruments are not needed, a problem that a metal aluminum label is prone to wrinkling and edge warping is solved, meanwhile, better plasticity is achieved, application of the metal label can be further broadened, and wide market prospects are achieved. 本发明公开了一种金属标签及其制备方法，该金属标签从下至上依次包括金属基材和印刷层，金属基材从下至上依次包括第一金属箔和铝箔，第一金属箔为锡箔或铅箔。本发明的有益效果为：本发明提出的金属标签设计巧妙，生产成本低，无需特殊设备仪器，解决了金属铝标签易出现起皱和翘边的问题，同时具备更好的可塑性，能够进一步拓宽金属标签的应用，具有广阔的市场前景。
