Embodiment 1
[0036] 1.1 Gravure printing
[0037] The two-dimensional code data is generated by a dedicated database and downloaded to the data package. Each two-dimensional code data contains 5-digit alphabetic symbols and 10-digit anti-counterfeiting codes. The anti-counterfeiting database can be established to query the authenticity of the data.
[0038] For gravure printing, the environment needs to be kept dry and ventilated, the temperature is controlled at 18-30°C, and the humidity is at 50±20%. Use a special inkjet printer, inspection equipment and special ink, after determining the printing position of the two-dimensional code and barcode according to the printing layout, install the inkjet equipment on the printing line, and before the color printing process, the inkjet printer prints the two-dimensional code and barcode One-time printing on PET polyester film (composite with aluminized film), and scan the printing effect for inspection, read successfully and continue to print; ...
Embodiment 2
[0044] PET polyester film with a total thickness of 18 μm is used as the printing material. Before the color printing process, the anti-counterfeiting two-dimensional code data is sprayed onto the film through a special inkjet printer, and the inkjet effect is tested. After confirming that it is qualified, the printing machine moves forward. The subsequent 12-color printing is completed at a speed of 100m / min.
[0045] After the two-dimensional code printing is completed, the composite workshop performs composite at a speed of 80m / min, and the temperature is controlled at 120-180 degrees. The coating amount of composite glue is 2.5g / m 2 , and after compound drying at 110°, curing and curing for 48 hours, then the barrel making is completed in the can factory and delivered for subsequent production.
[0046] After the paint production workshop receives the packaging barrel, it first checks the printing effect of the QR code and bar code, and starts production and filling after ...
Embodiment 3
[0048] It is basically the same as Example 2, except that after the two-dimensional code printing is completed, the composite workshop performs composite at a speed of 120m / min, the temperature is controlled at 150-160 degrees, and the coating amount of composite glue is 3.5g / m 2 , and after composite drying at 100°, curing and curing for 40 hours.
[0049]For each embodiment, after testing, no rust or rust spots can be achieved for more than 168 hours under standard salt spray test conditions. In the invention, the variable two-dimensional code is sprayed on the film by gravure back printing, and then compounded with the container to obtain the coating anti-counterfeiting package. The present invention cleverly arranges the variable two-dimensional code on the packaging container, realizes the unique identity of the product and cannot be damaged by smearing, and can also realize many functions such as packaging anti-counterfeiting and traceability, and effectively combats cou...
