Description

Laser white bottom two-dimensional code packing material

Technical Field

The utility model belongs to the technical field of the aluminium technology is scrubbed in the seal, concretely relates to physics washes white end two-dimensional code packing material of laser that aluminium technology made.

Background

The traditional aluminum washing process is a chemical aluminum washing process aiming at the cleaning of an aluminum-plated film and the partial hollow cleaning, and the chemical aluminum washing process mainly comprises two types of aluminum removal: one is to remove aluminum by alkali washing, and the other is to remove aluminum by water washing. The process flow of alkaline washing aluminum comprises the following steps: aluminizing → surface printing → washing aluminum. The process flow of water washing aluminum removal: common transparent film → inner print → aluminizing → aluminum washing. The chemical aluminum washing process has large aluminum removal pollution and is not environment-friendly. For the aluminum removing application of the traditional aluminum washing process, reference can be made to patent documents such as "a method for producing OVD two-dimensional code hot stamping foil by the aluminum washing process (CN 102700285B)" and "an aluminum washing process for radiation-plated medium cigarette packets (CN 104863020A)".

The applicant encounters a technical problem in printing packages such as toothpaste boxes of a certain manufacturer. The toothpaste box is made of mirror-surface silver cardboard, and the applicant and other supplier printing factories print the toothpaste box by using an offset printing machine. According to the requirement of national food safety law on food code-assigning tracing, manufacturers require code-assigning on toothpaste boxes. The existing code-giving process is that the card paper is firstly put on a special code-spraying platform to be sprayed with a two-dimensional code, and then the card paper is moved to an offset press to finish printing and oil-polishing protection. If the two-dimensional code is directly sprayed and printed on the mirror silver card paper, the problem that a mobile phone of a consumer is difficult to scan the code is caused because the two-dimensional code is not a white background but a silver mirror reflective background. In order to make the two-dimensional code have a white background, the applicant and other printing factories of suppliers have to put paper on an offset printing machine to print a white ink base, then move the paper to a special code spraying platform to spray and print the two-dimensional code, and finally move the paper back to the offset printing machine to print other pictures and texts and to polish the oil for protection. Therefore, only one toothpaste box required by a manufacturer needs to move and print thousands of tons of silver paperboard back and forth three times every year, and the efficiency is low and the cost is high.

How to reduce the printing frequency of back and forth movement, improve the production efficiency and reduce the production cost is a technical problem to be solved urgently in the printing and coding industry.

The utility model provides a white end two-dimensional code packing material of laser, includes white base paper layer and aluminize layer and two-dimensional code pattern layer on it, its characterized in that: local areas on the aluminum-plated layer are removed by laser melting; the removed local area forms a transparent window; the white base paper layer exposed out of the transparent window forms a white bottom layer of the two-dimensional code information layer. It is desirable to adjust the laser output energy intensity so that only the aluminized layer is melted and removed (rather than vaporized) so that the white base paper layer remains intact and not burned by the laser.

Preferably, a transparent thin film layer covers the aluminum plating layer and the white base material layer, only a local area on the aluminum plating layer is removed by laser melting, and the transparent thin film layer is intact and is not removed by the laser melting. In other words, the laser beam is transmitted through the transparent film to irradiate a local area of the aluminum plating layer, and only the aluminum plating layer is melted (not gasified), broken, and cooled to be dust, so as to eliminate reflection, i.e., extinction. Thus, a local region of the aluminum plating layer irradiated with the laser beam becomes a transparent window.

Preferably, the dust generated after the aluminized layer is removed by laser melting is sealed between the transparent film layer and the white base material layer, so that leakage is avoided, and a dust-free workshop with higher cleanliness requirement is not polluted.

Preferably, the white substrate layer is intact and not burned by the laser.

Preferably, the front surface of the aluminum-plated layer is provided with a dark transparent (e.g., transparent red, transparent purple, transparent blue, etc.) layer; the partial area which is not removed on the aluminum plating layer forms a dark two-dimensional code pattern layer; the removed local area on the aluminum plating layer forms a white bottom layer of the two-dimensional code pattern layer.

Compared with the prior art, the utility model discloses following beneficial technological effect can produce.

The process can replace the prior art for printing ink white bottom, and the popularization and application of the laser aluminum washing white bottom printing process can reduce the one-time process for printing ink white bottom, improve the productivity by more than 33 percent in the production of packing materials such as background product toothpaste boxes and the like, and reduce the printing processing cost by about one third.

And secondly, the environment is promoted. The traditional aluminum washing process aims at the process technology of cleaning an aluminum-plated film and partially hollowing out and cleaning, chemical solutions such as sodium hydroxide are needed to dissolve the aluminum-plated layer in a partial area, and the traditional aluminum washing process is large in pollution and not environment-friendly. By adopting the utility model, chemical solutions such as sodium hydroxide and the like are not needed, which is beneficial to promoting environmental protection.

Thirdly, laser dust does not leak. The transparent film layer can seal laser dust, cannot be leaked, and cannot pollute a dust-free workshop.

Detailed Description

The first embodiment.

As shown in FIG. 1 and FIG. 2, 230g/m is selected²The mirror-like silver card paper 6 coated with the aluminized layer 2 is printed (commonly called transfer/transfer printing) on the toothpaste box.

Laser beams of a JJY-DB-500B type laser machine are adopted to carry out laser irradiation on a local area 3 appointed by a box surface so as to melt and remove the aluminum coating 2 of the local area 3 and enable the removed local area to form a transparent window; thereby exposing the white base paper layer 1 to form a local white bottom layer 7 of laser washed aluminum. Preferably, the intensity of the laser output energy is adjusted so that only the aluminized layer is properly melted and removed, while the white base paper layer 1 is intact and not burned by the laser.

And (3) adopting an ink-jet printer to jet-print ink on a local area 3, namely a local white bottom layer 7, of the toothpaste box to obtain the laser white bottom two-dimensional code package.

Example two.

As shown in FIG. 3 and FIG. 4, 230g/m is selected²The mirror silver card paper 6 coated with the aluminizer is commonly called transfer/transfer printing to print the toothpaste box. Namely, the toothpaste box is printed by using a paperboard 6 consisting of a transparent film layer 5, an aluminum coating layer 2 and a white base paper layer 1.

Laser beam of a laser engraving machine is used for irradiating laser on a designated local area 3 of the box surface through the transparent film layer 5 so as to pulverize the aluminized layer 2 of the local area 3, thereby exposing the white base paper layer 1 and forming a local white bottom layer 7 of laser-washed aluminum. Preferably, the intensity of the laser output energy is adjusted so that only the aluminized layer is properly melted and removed, while the white base paper layer 1 is intact and not burned by the laser. Thus, even if a small amount of laser contamination is generated during laser irradiation production, the contamination does not leak and pollute the environment because of the protection of the transparent thin film layer 5.

Ink is sprayed and printed on a local area 3 of the toothpaste box, namely a local white bottom layer 7, by adopting a code spraying machine, and the laser white bottom two-dimensional code paper box is formed.

Example three.

As shown in FIG. 5 and FIG. 6, 230g/m is selected²The mirror gold red (formed by mirror silver and transparent red) card paper 6 coated with an aluminum plating film (commonly called transfer/transfer printing) is printed on the toothpaste box.

A laser beam of a laser engraving machine is adopted to irradiate and melt a white bottom layer 7 of the two-dimensional code pattern 4 in a local area 3 designated on the box surface through a transparent red layer, namely a dark transparent layer 8. Thus, the two-dimensional code pattern 4 with the golden red color is formed in the partial area which is not melted by the laser irradiation, and the two-dimensional code pattern 4 does not need to be jet-printed by an ink jet printer. Preferably, the intensity of the laser output energy is adjusted so that only the aluminized layer 2 is properly melted and removed, while the white base paper layer 1 is intact and not burned by the laser.

Example four.

See the transparent thin film layer 5 and the aluminized layer 2 in fig. 4. The laser aluminum washing process in the Chinese patent 'method for producing OVD two-dimensional code hot stamping foil by aluminum washing process' (CN102700285B) 'and' aluminum washing process for radiating medium-plated cigarette packet '(CN 104863020A)'.

The laser beam of the laser engraving machine is adopted to scan the appointed local area 3 through the transparent film layer 5 so as to pulverize/remove the aluminized layer 2 of the local area 3, thus forming the laser aluminum-washing thermoprinting cigarette packet which is equivalent to the method (CN102700285B) for producing the OVD two-dimensional code thermoprinting foil by the aluminum-washing process in the Chinese patent.
