Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette materials, and in particular relates to an environmentally friendly laser aluminum-plated film. Background Art

[0002] The current laser lining paper composite processing technology for cigarettes mostly uses paper and aluminum foil to composite first, and then transfers the laser information layer on the film layer to the aluminum foil to produce cigarette lining paper with laser effect.

[0003] First, the current laser lining paper for cigarettes uses a large amount of aluminum in the production process, which is costly and puts great pressure on environmental protection. After the paper and aluminum foil are compounded, the laser information layer on the film layer is transferred to the aluminum foil, and the film layer needs to be processed through a molding process to form a laser information layer, which will consume a lot of production time and cost for the processing of laser lining paper for cigarettes.

[0004] Secondly, the existing laser lining paper for cigarettes is relatively simple in anti-counterfeiting technology, easy to imitate and difficult for consumers to identify. For example, the Chinese patent authorization announcement number is CN203373615U, which discloses an anti-counterfeiting lining paper for cigarette packaging, including aluminum foil, ordinary lining paper, watermark anti-counterfeiting bottom paper and seamless laser transfer film aluminum layer. The watermark anti-counterfeiting bottom paper, aluminum foil, ordinary lining paper and seamless laser transfer film aluminum layer are sequentially compounded together by adhesives. This product uses a variety of materials as the lining paper for cigarette packaging, and combines the characteristics of each material to ensure the anti-counterfeiting performance of the lining paper while significantly improving the formability and sealing of the product. The product combines multiple anti-counterfeiting methods such as embossing, watermark bottom paper, laser anti-counterfeiting, etc., and has a bright and fashionable appearance; its anti-counterfeiting technology relies too much on technology and cannot keep up with the current trend of intelligent technology development;

[0005] Therefore, an environmentally friendly laser aluminum-plated film is proposed. Utility Model Content

[0006] The utility model solves the problem that the existing cigarette lining paper has a large amount of aluminum material used in the production process, is high in cost, and is not conducive to environmental protection; another is to improve and simplify the composite processing technology of laser-effect cigarette lining paper, directly use paper and the laser aluminum film of the cigarette lining paper of the utility model to composite, and produce cigarette lining paper with the same laser effect as the current one, which greatly reduces the time and cost of composite processing of laser cigarette lining paper and has a better anti-counterfeiting effect.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An environmentally friendly laser aluminum-plated film comprises a laser aluminum film body, wherein the laser aluminum film body comprises a base aluminum layer, a laser information layer arranged on the base aluminum layer, and an anti-counterfeiting mark printed on the outer surface of the laser aluminum film body;

[0009] The base aluminum layer includes a thin film layer and an aluminum layer;

[0010] The laser information layer is a band-shaped structure;

[0011] The anti-counterfeiting mark is an anti-counterfeiting QR code.

[0012] Preferably, the aluminum layer is made by spraying aluminum wire using a vacuum aluminum plating machine, and its thickness is ± angstroms.

[0013] Preferably, the laser information layer is distributed on the upper part, the middle part and the lower part of the laser aluminum film body.

[0014] Preferably, special glue is coated between the base aluminum layer and the laser information layer.

[0015] Preferably, the special glue is a water-based acrylate-modified polyurethane transfer coating.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The base aluminum layer is made by vacuum aluminum plating, which is much thinner than the conventional composite aluminum foil. Therefore, the amount of aluminum used is greatly reduced, saving costs and benefiting environmental protection.

[0018] The vacuum aluminum plating process is mature and the equipment runs stably. The process of coating special glue on the base aluminum layer and performing the molding process on one side of the base aluminum layer coated with glue has been developed and can be put into mature production. The equipment runs stably. Therefore, large-scale production can be achieved. At the same time, by changing the formula, dosage, viscosity of the special glue and the process parameters of the molding process, aluminum foil composited with cigarette lining paper with different laser effects can be produced, which can be suitable for laser aluminum film composited with cigarette lining paper with diversified laser information layers.

[0019] (2) By printing anti-counterfeiting marks on the outer surface of the laser aluminum film body, using printed anti-counterfeiting QR codes, and developing a small program or APP, the QR codes can be authenticated using a smartphone to improve the anti-counterfeiting effect. Compared with anti-counterfeiting through process technology, information technology anti-counterfeiting is more accurate and simple, and personnel can easily distinguish between the real and the fake without receiving training.

[0020] (3) The utility model can directly compound the cigarette liner paper with paper during compound processing to produce cigarette liner paper with the same laser effect as the current one, which greatly reduces the time and cost of the current compound processing of cigarette liner paper and improves and optimizes the process of compound processing of cigarette liner paper.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and Figure 2 As shown, the present embodiment provides an environmentally friendly laser aluminum-plated film, comprising a laser aluminum film body, the laser aluminum film body comprising a base aluminum layer, a laser information layer arranged on the base aluminum layer and an anti-counterfeiting mark printed on the outer surface of the laser aluminum film body, the anti-counterfeiting mark is an anti-counterfeiting QR code 3, the base aluminum layer comprises a film layer 1 and an aluminum layer 2, the aluminum layer 2 is made of aluminum wire sprayed by a vacuum aluminum plating machine, and its thickness is 380±20 angstroms, the laser information layer is a strip structure distributed in the upper, middle and lower parts of the laser aluminum film body, and a special glue is coated between the base aluminum layer and the laser information layer, the special glue is a water-based acrylate modified polyurethane transfer coating, and nano-silver antibacterial agent is added to inhibit the growth and reproduction of bacteria, thereby improving its hygienic performance and service life.

[0027] The production process is as follows:

[0028] Step 1: Make a base aluminum layer by a vacuum aluminum plating machine;

[0029] like Figure 1 As shown, a vacuum aluminum coating machine is used to spray high-temperature vaporized aluminum wire onto one side of the film layer 1, and then the film layer 1 is cooled by a cooling roller and formed by a pressing roller to form a base aluminum layer 2;

[0030] Before the winding process, the base aluminum layer is peeled off from the film layer 1 and wound up through a winding process, and the film layer 1 can be reused according to the above process flow.

[0031] Step 2: Making the laser information layer by a coating machine and a molding machine;

[0032] Using a spray coating head and a coating machine with an oven drying process, the special glue is transported to the coating head through a pipe and sprayed on one side of the base aluminum layer, and then dried in an oven to form;

[0033] Using a molding machine with a nickel plate roller containing specific patterns or text, the side coated with special glue is subjected to a molding process by the roller to form a laser information layer on the side of the base aluminum layer coated with glue.

[0034] Step 3: Print the anti-counterfeiting mark through a printing press;
