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...

Abstract

The invention discloses a paint anti-counterfeit package and a preparation method thereof. The paint anti-counterfeit package comprises a container for storing paint and a film layer which is compounded to the outer surface of the container; and the film layer is provided with a variable two-dimensional code. According to the paint anti-counterfeit package and the preparation method thereof, the variable two-dimensional code is printed on a film in a spraying mode through gravure inner printing at first, then, the film and the container are combined, and the paint anti-counterfeit package is obtained; and the variable two-dimensional code is ingeniously arranged on the package container, it is achieved that the identity of the product is unique and cannot be damaged by scribbling, in addition, package anti-counterfeit tracing and other functions can be achieved, and counterfeit manufacturing and selling are effectively fought.

Description

technical field [0001] The invention belongs to the anti-counterfeiting field of paint packaging, and in particular relates to an anti-counterfeiting paint packaging and a preparation method thereof. Background technique [0002] Existing interior wall paints, that is, latex paint products are packaged in 18-20L tinplate drums, and the exterior design uses iron printing technology to directly print patterns on the outside of the iron drum body. The appearance is very easy for counterfeiters to take pictures and imitate. Although there are online barcodes for product anti-counterfeiting and control, ordinary inkjet inks can be easily wiped off due to the use of specific organic solvents, giving counterfeiters a chance. [0003] Based on the above status quo, it is necessary to improve the packaging, improve the anti-counterfeiting ability, and crack down on counterfeiting and sales. Contents of the invention [0004] The purpose of the present invention is to provide a coa...
