Embodiment 1
[0044] The preparation method of the bottled water sealing label, the specific steps are as follows:
[0045] 1) Select a double-sided corona PET with a thickness of 22 μm, and use a coating machine to coat a well-proportioned coating on one side of the PET to form an imaging layer 5. The coating ratio is: FL-7202A1: FL-7202A2: butyl acetate Ester = 10:130:0.52;
[0046] 2) Use a molding and embossing gravure printing machine to mold on the imaging layer 5, copy the holographic information on the molding plate to the imaging layer 5 to form a holographic laser layer 6; then coat the holographic laser layer 6 with aluminum to form an aluminum coating layer 7 ; The square resistance value of the described aluminized layer 7 is 0.56;
[0047] 3) Utilize the secondary post-printing technology, and use a coding machine to print a variable two-dimensional code on the aluminized layer 7 to form a variable digital layer 8;
[0048] 4) Use a gravure printing machine to perform forwar...
Embodiment 2
[0069] The preparation method of the bottled water sealing label, the specific steps are as follows:
[0070] 1) Select a double-sided corona PET with a thickness of 30 μm, and use a coating machine to coat a well-proportioned coating on one side of the PET to form an imaging layer 5. The coating ratio is: FL-7202A1: FL-7202A2: butyl acetate Ester = 10:130:0.52;
[0071] 2) Use a molding and embossing gravure printing machine to mold on the imaging layer 5, copy the holographic information on the molding plate to the imaging layer 5 to form a holographic laser layer 6; then coat the holographic laser layer 6 with aluminum to form an aluminum coating layer 7 ; The square resistance value of the described aluminized layer 7 is 0.6;
[0072] 3) Utilize the secondary post-printing technology, and use a coding machine to print a variable two-dimensional code on the aluminized layer 7 to form a variable digital layer 8;
[0073] 4) Use a gravure printing machine to perform forward...
