Preparation method of double-sided high-anti-counterfeiting environment-friendly label

The invention provides a preparation method of a double-sided high-anti-counterfeiting environment-friendly label. The preparation method comprises the following specific steps: (1) firstly, carryingout aluminizing processing on a pearlescent film to obtain a pearlescent aluminized film; (2) performing anti-counterfeiting printing on the front surface and the back surface of the pearlescent aluminized film; (3) then carrying out composite film pressing on the front surface of the printed pearlescent aluminized film; and (4) finally, compounding the reverse side of the printed pearlescent aluminized film with an adhesive. The label prepared by the method adopts double-sided printing, so that the front surface and the back surface of the label are provided with anti-counterfeiting patterns,and the anti-counterfeiting performance of the label is improved. According to the label prepared by the method, the pearlescent BOPP film or PET film material is subjected to an aluminizing process.The aluminized surface is
