Problems solved by technology

The hollow spray metallized paper produced by this technology has a certain anti-counterfeiting effect, but this process requires extremely high equipment, the system is relatively complicated, the equipment cost is high, and the investment is large. It belongs to a special edition, and the scope of use is limited to a certain extent
In addition, since the low surface energy oil may not be completely volatilized in the later stage, there will be poor adhesion of the printing ink layer or unstable labeling for the later printing or pasting of the logo. There is still a large room for improvement in this process.

Embodiment 1

[0036] Example 1 A direct-coated metallized aluminum paper with a hollow five-star pattern

[0037] The hollow pattern of this embodiment is attached figure 2 In the five-pointed star pattern shown, the color of the hollowed-out five-pointed star is off-white.

[0038] Implementation steps:

[0039] (1) Design the size and position of the five-pointed star pattern according to the needs, and laser or electric engrave the designed five-pointed star on the gravure plate roller. The five-pointed star area on the gravure plate roll is an area without mesh cells. The depth and shape of the mesh in the area with mesh holes should meet the wet ink volume of 8 ~ 10g / m 2 requirements.

[0040] (2) The gravure roller prepared by step (1) has a grammage of 87g / m 2 Coating of hollow base coat on paper. Use water-based paint as the primer, adjust the viscosity and solid content of the primer, control the speed of the vehicle and the pressure of the scraper when coating, and ensure...

Embodiment 2

[0045] Example 2 A hollow direct metallized aluminum paper with leaf effect

[0046] The hollow pattern of this embodiment is attached image 3 The leaf pattern shown, the cutout leaf color is silvery white.

[0047] Implementation steps:

[0048] (1) According to the attached image 3 The leaf pattern shown is designed to make a gravure roll, and the white areas of the leaves are areas without cells. The black area of ​​the leaves is the area with mesh holes, the depth and shape of the mesh holes should meet the wet ink volume of 3 ~ 4g / m 2 requirements.

[0049] (2) The grammage of the gravure roll prepared in step (1) is 225g / m 2 Coating of hollow base coat on paper. Use the electron beam curing coating as the primer, adjust the viscosity of the primer, control the speed of the vehicle, the pressure of the scraper, the dose of electron beam radiation, etc. during coating, and the coating after coating is required to be smooth and smooth. The hollow base coat is fo...

Embodiment 3

[0053] Example 3 A hollowed-out direct metallized aluminum paper with metal wire drawing effect

[0054] The hollow pattern of this embodiment is attached Figure 4 The metal brushed effect pattern shown, the hollowed out area is a near white area.

[0055] Implementation steps:

[0056] (1) According to the pattern design of the metal wire drawing effect, the gravure plate roller is designed and designed with different depths of cells. The depth of the cells varies from 0 to 30 microns. The brighter the metal surface, the more the cells The deeper the hole is, the more dull the metal surface is, the shallower the mesh is, and the depth of the mesh at the wire drawing mark is 0-4 microns.

[0057] (2) Use the gravure roll prepared in step (1) at a grammage of 55g / m 2 Coating of hollow base coat on paper. Use water-based paint as the primer, adjust the viscosity and solid content of the primer, control the speed of the vehicle and the pressure of the scraper when coating...

Abstract

The invention relates to a straight-metallized hollow aluminum paper and a production technology thereof, belonging to the technical field of package materials, decoration materials and production technology thereof. The straight-metallized hollow aluminum paper is characterized by sequentially comprising, from top to bottom, a protective coating (1), a metalized aluminum layer (2), a hollow priming coat (3) and paper (4). According to the production technology provided by the invention, the aluminum layer with patterns / character effects being similarly hollow is obtained by using a principle that ultra-thin metal aluminum layers are deposited on surfaces with different roughness and then different reflective effects can be shown. By using a gravure process principle as well as a technology of directly metallizing aluminum under vacuum, the straight-metallized hollow aluminum paper with the hollow pattern / character effects can be produced. The production technology mainly comprises four steps of designing and making gravure rollers, coating the hollow priming coat, metallizing the aluminum layer under vacuum and coating the protective coating, and further comprises coating a back coating. The straight-metallized hollow aluminum paper with different effects can be produced according to design needs.

Description

technical field [0001] The invention relates to a direct-coated metallized aluminum paper and a production process thereof, in particular to a direct-coated metallized aluminum paper with a hollow graphic effect and a production process thereof, and belongs to the technical field of packaging materials, decorative materials and production thereof. Background technique [0002] Metallized aluminum paper is a new type of packaging material that has emerged in recent years. The metal layer of this paper is thin, generally 20-50 nanometers thick, degradable, easy to recycle, and has good decorative effects. Compared with composite metal foil paper (such as composite Aluminum foil paper) consumes less metal resources and is an environmentally friendly packaging material that can be widely used in the packaging of cigarettes, alcohol, handicrafts, small appliances, gifts, food, tea and other fields, with a huge market capacity. But at present, the metal layer of this kind of meta...
