Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting label packaging and printing technology, and in particular to an environmentally friendly anti-counterfeiting label packaging and printing process. Background Technology

[0002] Anti-counterfeiting labels are proof labels that allow people to distinguish between genuine and counterfeit products and prevent counterfeiting. They are used by people to check the authenticity of products and distinguish the quality of products during the product circulation process.

[0003] The existing anti-counterfeiting labels are mostly made of ordinary materials during the production and processing, and the printing process is often designed to improve printing efficiency, resulting in poor process effects. As a result, the printing ink on the anti-counterfeiting labels is easily affected by the surrounding adverse environment, causing problems such as blurring and fading, which reduces the lifespan of the anti-counterfeiting labels.

[0004] To reduce the impact of external environmental factors on printing inks, existing printing processes typically involve laminating the label surface to protect the ink. However, these laminations often use plastic films, which are difficult to degrade and cause environmental pollution when the anti-counterfeiting labels are not in use. Therefore, we propose an environmentally friendly anti-counterfeiting label packaging and printing process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly anti-counterfeiting label packaging and printing process. This process avoids the environmental pollution caused by the non-degradability of anti-counterfeiting labels when not in use, while also enhancing the protective performance of the anti-counterfeiting label packaging and improving its service life.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: an environmentally friendly anti-counterfeiting label packaging and printing process, comprising the following steps:

[0007] S1: Select the appropriate printing press unit on the offset printing press according to the printing requirements of the anti-counterfeiting label packaging;

[0008] S2: The label roll and packaging roll to be printed are unwound intermittently, and two sets of unwound mechanisms are used in a symmetrical unwound application. Both the label roll and the packaging roll are biodegradable cardboard.

[0009] S3: Start two sets of unwinding mechanisms to unwind the label roll and the packaging roll. During the unwinding process, a coating mechanism is used to coat the adhesive surface of the unwound label roll with self-adhesive film. At the same time, a composite roller mechanism is used to composite the unwound label adhesive surface with the packaging surface to complete the bonding.

[0010] S4: The label packaging is transferred to the offset printing machine to use water-based ink for anti-counterfeiting printing on the printed surface of the label. The printed label packaging is then transferred to the hot stamping machine to dry the ink using UV drying and to design hot stamping patterns.

[0011] S5: The printed labels are packaged and transferred to the varnishing machine, where a layer of varnish is applied to the ink surface of the printed label using a UV varnishing process.

[0012] S6: Transfer the printed label packaging to the laminating machine and apply liquid packaging film to the surface of the label packaging;

[0013] S7: The laminated label packaging is wound up using a winding mechanism, and the wound label packaging is sent into the cutting equipment for die-cutting.

[0014] Preferably, the biodegradable paperboard used in step S2 is cotton paper.

[0015] Preferably, the water-based ink used in step S4 is made by mixing water-soluble acrylic modified polyurethane resin, organic pigments, defoamer, and purified water.

[0016] Preferably, the Water-based inks The proportions of water-soluble acrylic-modified polyurethane resin, organic pigments, defoamer, and purified water are as follows:

[0017] Water-soluble acrylic-modified polyurethane resin: 20%–30%

[0018] Organic pigments: 25%–35%

[0019] Defoamer: 5%–10%

[0020] Purified water: 25%–50%

[0021] Preferably, the liquid packaging film used in step S6 is made of a mixture of ethyl cellulose, epoxy resin, dibutyl phthalate, waterproofing agent, antibacterial agent, and corrosion inhibitor.

[0022] Preferably, the proportions of ethyl cellulose, epoxy resin, dibutyl phthalate, waterproofing agent, antibacterial agent, and corrosion inhibitor in the liquid packaging film are as follows:

[0023] Ethyl cellulose: 15%–25%

[0024] Epoxy resin: 20%–30%

[0025] Dibutyl phthalate: 20%–25%

[0026] Waterproofing agent: 8%–15%

[0027] Antibacterial agent: 6%–15%

[0028] Corrosion inhibitor: 6%–15%

[0029] Compared with existing technologies, the present invention has the following beneficial effects: This anti-counterfeiting label packaging uses easily degradable cardboard as the carrier material and water-based ink and liquid packaging film as printing and laminating materials. By using a variety of environmentally friendly materials for printing and processing, the anti-counterfeiting label packaging can avoid the problem of environmental pollution caused by the non-degradability of anti-counterfeiting labels when not in use, which is conducive to improving the environmental protection performance of anti-counterfeiting labels. At the same time, it can enhance the protective performance of anti-counterfeiting label packaging, which is conducive to avoiding the blurring and fading problems of printing ink on labels caused by the surrounding environment due to the influence of traditional process materials, and is conducive to improving the service life of anti-counterfeiting label packaging.

[0033] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0034] Example 1

[0035] As attached Figure 1-2 The environmentally friendly anti-counterfeiting label packaging and printing process shown includes the following steps:

[0036] S1: Select the appropriate printing press unit on the offset printing machine according to the printing requirements of the anti-counterfeiting label packaging.

[0037] Selecting the appropriate printing press unit on a offset printing press can improve the printing effect of anti-counterfeiting labels. At the same time, offset printing is simple to operate and saves printing costs.

[0038] S2: The label rolls and packaging rolls to be printed are unwound intermittently, and two sets of unwound mechanisms are used in a symmetrical unwound application. Both the label rolls and packaging rolls are biodegradable paperboard, and the biodegradable paperboard is cotton paper.

[0039] Intermittent unwinding ensures no tension changes during the unwinding of label and packaging rolls, reducing constant adjustments during the unwinding process. This method can be applied to both flatbed and rotary label presses. Due to its slow unwinding speed, it further ensures accurate registration during printing. Using biodegradable cardboard as the printing material helps avoid the environmental pollution caused by the non-biodegradability of anti-counterfeiting labels when not in use.

[0040] S3: Start two sets of unwinding mechanisms to unwind the label roll and packaging roll. During the unwinding process, a coating mechanism is used to coat the adhesive surface of the unwound label roll with self-adhesive film. At the same time, a composite roller mechanism is used to composite the unwound label adhesive surface with the packaging surface to complete the bonding.

[0041] The label roll and packaging roll are bonded by applying self-adhesive. The self-adhesive can be repeatedly applied and the material is environmentally friendly. When the label is peeled off, the self-adhesive will not leave any residue, which helps to keep the surface of the packaging roll clean. This increases the environmental friendliness and recyclability of the anti-counterfeiting label itself, and also increases the service life of the anti-counterfeiting label itself.

[0042] S4: The label packaging is transferred to the offset printing press, where water-based ink, made from a mixture of water-soluble acrylic modified polyurethane resin, organic pigments, defoamer, and purified water, is used to print anti-counterfeiting designs on the label surface. The printed label packaging is then transferred to the hot stamping machine, where the ink is dried using UV drying and hot stamping patterns are designed.

[0043] Compared to traditional printing inks, water-based inks are more environmentally friendly during application, avoiding the pollution problems associated with traditional printing inks. This improves safety during operation and helps protect the health of operators. At the same time, it makes the colors of printed materials more vibrant and rich. Combined with hot stamping patterns, it can effectively enhance the richness of colors and thus improve the quality of the anti-counterfeiting label itself.

[0044] S5: The printed labels are transferred to the varnishing machine and a layer of varnish is applied to the ink surface of the printed label using the UV varnishing process.

[0045] After the printing ink on the surface of the anti-counterfeiting label is dried by UV drying process, a varnish is applied. The varnish can protect the ink layer, prevent moisture and water, and improve the gloss of the anti-counterfeiting label surface.

[0046] S6: The printed label packaging is transferred to the laminating machine, where a liquid packaging film made of ethyl cellulose, epoxy resin, dibutyl phthalate, waterproofing agent, antibacterial agent, and corrosion inhibitor is used to coat the surface of the label packaging.

[0047] Using liquid packaging film as a surface coating for anti-counterfeiting labels can replace traditional plastic film as a coating, avoiding the environmental pollution caused by the non-degradability of traditional plastic film when not in use. This helps improve the environmental performance of anti-counterfeiting labels during use. At the same time, liquid packaging film can protect the ink, waterproof and moisture-proof, increase the label strength, and enhance the three-dimensional effect of the pattern, which helps to further improve the quality of anti-counterfeiting labels.

[0048] S7: The laminated label packaging is wound up using a winding mechanism, and the wound label packaging is sent into the cutting equipment for die-cutting.

[0049] By die-cutting the label packaging after lamination, the whole label packaging can be cut into several small anti-counterfeiting label packagings for use.

[0050] Example 2

[0051] Based on the above embodiment 1, Step S4 corresponding Water-based inks The proportions of water-soluble acrylic-modified polyurethane resin, organic pigments, defoamer, and purified water are as follows:

[0052] Water-soluble acrylic-modified polyurethane resin: 25%

[0053] Organic pigments: 30%

[0054] Defoamer: 5%

[0055] Purified water: 40%

[0056] Based on the component ratio, water-soluble acrylic-modified polyurethane resin, organic pigments, defoamer, and purified water are sequentially poured into a mixing machine and thoroughly stirred to obtain the desired product. Water-based inks, because water-based inks contain... It is made of water-soluble acrylic modified polyurethane resin and organic pigments, thus it is environmentally friendly and can avoid polluting the environment during application and will not cause pollution to the working environment.

[0057] Example 3

[0058] Based on Example 1 above, the proportions of ethyl cellulose, epoxy resin, dibutyl phthalate, waterproofing agent, antibacterial agent, and corrosion inhibitor in the liquid packaging film corresponding to step S6 are as follows:

[0059] Ethyl cellulose: 25%

[0060] Epoxy resin: 25%

[0061] Dibutyl phthalate: 20%

[0062] Waterproofing agent: 12%

[0063] Antibacterial agent: 8%

[0064] Corrosion inhibitor: 10%

[0065] Based on the component ratio, water-soluble acrylic modified polyurethane resin, organic pigments, defoamer, and purified water are sequentially poured into a mixing machine and thoroughly stirred to obtain a liquid packaging film. During application, the liquid packaging film protects the ink, is waterproof and moisture-proof, increases label strength and the three-dimensional effect of the pattern, and is easily degradable.

[0066] In summary, this environmentally friendly anti-counterfeiting label packaging and printing process avoids the environmental pollution caused by the non-degradability of anti-counterfeiting labels when not in use, thus improving the environmental performance of anti-counterfeiting labels and enhancing the protective performance of the packaging, thereby extending its service life. The basic principles, main features, and advantages of this invention have been shown and described above.
