Figure 2 The diagram above illustrates the dimensions of a reinforcing layer and a first and a second base paper layer. Figure 3 The diagram above illustrates a process flow chart of a laser transfer cigarette tipping paper manufacturing method.
[0019] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0020] The following description, in conjunction with the accompanying drawings and some preferred embodiments conforming to the present invention, provides a more detailed account of a laser transfer cigarette tipping paper and its processing method.
[0021] The laser transfer cigarette tipping paper of the present invention is used in tobacco products including cigarette holders. One specific embodiment of the laser transfer cigarette tipping paper of the present invention comprises a first base paper layer, a reinforcing layer, a pattern layer, and a second base paper layer. The number of the second base paper layer and the reinforcing layer in this tipping paper can both be at least one (i.e., greater than or equal to one), while the number of the first base paper layer and the pattern layer can both be one. The first base paper layer, the reinforcing layer, the pattern layer, and the second base paper layer can be laminated together using hot melt adhesive or hot pressing processes. This application does not limit the manner in which the first base paper layer, the reinforcing layer, the pattern layer, and the second base paper layer are combined.
[0022] Figure 1 A schematic cross-sectional view of two types of tipping paper for laser transfer cigarettes is shown. For example... Figure 1 As shown in Figure a, the laser transfer cigarette tipping paper includes a first base paper layer 101, a reinforcing layer 102, a second base paper layer 103, and a pattern layer 104.Figure 1 As shown in Figure b, the laser transfer cigarette tipping paper includes a first base paper layer 101, two reinforcing layers 102, two second base paper layers 103, and a pattern layer 104.
[0023] It should be understood that the structure of the tipping paper for laser transfer cigarettes described in this instruction manual is not limited to... Figure 1 As shown, this can be expanded according to actual needs. Specifically, the number of reinforcing layer 102 and second base paper layer 103 can be increased as needed, and the number of reinforcing layer 102 and second base paper layer 103 can also be unequal. In one example, the reinforcing layer 102 and second base paper layer 103 in the laser transfer cigarette tipping paper can be increased in the same number. In another example, the number of second base paper layers 103 in the laser transfer cigarette tipping paper is increased more than the number of reinforcing layers 102, that is, no reinforcing layer may be provided between the two second base paper layers 103.
[0024] The first base paper layer 101 and the pattern layer 104 are the two outer layers of the laser transfer cigarette tipping paper. After assembling the tobacco product, the laser transfer cigarette tipping paper is arranged around the mouthpiece in the tobacco product, wherein one side of the first base paper layer 101 is in direct contact with the mouthpiece, while the pattern layer 104 is exposed on the outside.
[0025] The composition of the first base paper layer 101 and the second base paper layer 103 can be entirely the same or partially the same. Both base paper layers 101 and 103 can be obtained from wood pulp, leaf pulp, etc., and contain a large amount of cellulose. In one example, the composition of both the first base paper layer 101 and the second base paper layer 103 contains 15-40% bleached softwood pulp and 60-85% bleached hardwood pulp. The identical pattern layer 104 is obtained by printing, hot stamping, or other processes on one side of the second base paper layer 103. In one example, a pattern layer 104 containing a laser pattern can be obtained using a hot stamping process such as laser-etched plain gold foil.
[0026] The reinforcing layer 102 can be disposed between the first base paper layer 101 and the second base paper layer 103. When the tipping paper for laser transfer cigarettes includes multiple layers of second base paper layers 103, the reinforcing layer 102 can be disposed between two layers of second base paper layers 103, or the reinforcing layer 102 can be disposed between both the first base paper layer 101 and the second base paper layer 103. This specification does not specify a particular number of reinforcing layers 102, which can be determined according to the actual situation.
[0027] The reinforcing layer 102 can be configured as a mesh structure. As mentioned earlier, both the first base paper layer 101 and the second base paper layer 103 contain a large amount of cellulose. In one example, substances containing hydroxyl, amino, etc., can be provided in the reinforcing layer 102. These substances can form hydrogen bonds, covalent bonds, etc., with cellulose, so that the reinforcing layer 102 can be firmly attached to the first base paper layer 101 or the second base paper layer 103. In this way, when the laser transfer cigarette tipping paper is subjected to stress, the mesh structure of the reinforcing layer 102 can improve the strength of the laser transfer cigarette tipping paper through hydrogen bonds, etc., effectively preventing crack propagation and facilitating the maintenance of the appearance and structural integrity of the smoking product.
[0028] In one example, the reinforcing layer 102 can be a hydroxyl-rich substance such as a polypeptide or protein. Protein fibers (such as silk fibroin, collagen, and fibroin) are fibrous proteins, and their inherent fibrous structure gives them good elasticity and toughness. Preferably, protein fibers can be incorporated into the reinforcing layer 102. The content of protein fibers in the reinforcing layer 102 can be determined according to the actual situation.
[0029] The reinforcing layer 102 can be made of composite materials. Specifically, in addition to protein fibers, other materials can also be incorporated. In one example, nanocellulose can be incorporated into the reinforcing layer 102. Nanocellulose has a high specific surface area and good mechanical properties. Through the synergistic effect of protein fibers and nanocellulose, the strength of the laser transfer cigarette tipping paper can be further improved. Experiments have shown that compared to tipping paper with a reinforcing layer 102 composed entirely of protein fibers, the tear index of tipping paper with a reinforcing layer 102 composed of 50% protein fibers and 50% nanocellulose can be increased by 45%.
[0030] Normally, the first base paper layer 101 and the second base paper layer 103 are the same size, and in the tipping paper for laser transfer cigarettes, the edges of the first base paper layer 101 and the second base paper layer 103 overlap. To prevent the protein fibers and other hydrogen-bonded substances in the reinforcing layer 102 from coming into direct contact with the air, the edges of the mesh structure in the reinforcing layer 102 can be spaced a certain distance from the edges of the first base paper layer 101 and the second base paper layer 103.
[0031] In one example, the size of the mesh structure in the reinforcing layer 102 is smaller than the size of the first base paper layer 101 and the second base paper layer 103. Figure 2 An example diagram showing the dimensions of a reinforcing layer, a first base paper layer, and a second base paper layer is provided, as follows: Figure 2 As shown, the edge of the mesh structure in the reinforcing layer 102 can be 1-2 mm away from the edge of the first base paper layer 101 and the second base paper layer 103.
[0032] When the tipping paper absorbs liquid fragrance, humectant, water, or any moisture or humidity around the paper, the absorbed liquid can thin the tipping paper, thereby affecting the appearance and structural integrity of the smoking article. In one example, absorbent and / or oil-absorbing materials can be provided in the mesh of the reinforcing layer 102.
[0033] Furthermore, to avoid the influence of water- and oil-absorbing substances on the network structure, microcapsules comprising a capsule wall and a capsule core can be constructed, with the oil-absorbing material and / or diatomaceous earth placed inside the microcapsule; that is, the capsule core of the microcapsule is a water-absorbing material and / or an oil-absorbing material. Specifically, the water-absorbing material can be chitosan, which can absorb moisture and form a gel film, while the oil-absorbing material can be porous and stable diatomaceous earth. In one example, chitosan and diatomaceous earth can be mixed as the capsule core.
[0034] To enable the microcapsules to be fixed within the grid, the capsule wall can be made of a material that forms hydrogen bonds with the cellulose, thereby securing the microcapsules within the grid. In one example, the capsule wall can be a polypeptide or protein.
[0035] The above-mentioned microcapsules can be prepared by: adding protein fibers and other substances to warm water, stirring and dispersing them evenly, and then cooling; adding chitosan, diatomaceous earth and other substances to the cooled solution, stirring, further cooling, sieving and washing to obtain microcapsules.
[0036] Based on this, the present invention also provides a processing method for laser transfer cigarette tipping paper, which is used to prepare the above-mentioned laser transfer cigarette tipping paper. Figure 3 A schematic flowchart of a processing method for laser-transfer cigarette tipping paper is shown, as follows: Figure 3 As shown, the processing method of the laser transfer cigarette tipping paper includes the following steps: Step S301: Prepare a first base paper layer and at least one second base paper layer, and number the second base paper layer.
[0037] The first and second base paper layers can have the same composition, and both can contain a large amount of cellulose. For example, the first and second base paper layers can be prepared from leaf pulp or similar raw materials. After the tobacco product containing the mouthpiece is processed, one side of the first base paper layer is in direct contact with the mouthpiece, while the second base paper layer is not in direct contact with the mouthpiece.
[0038] The second base paper layer can be multiple layers. The thickness and composition of the multiple second base paper layers in the same laser transfer cigarette tipping paper can be the same or different, and this instruction manual does not impose specific restrictions on this. Since different second base paper layers are located in different positions on the laser transfer cigarette tipping paper, the second base paper layers can be numbered first, and then the laser transfer cigarette tipping paper can be laminated according to the numbers.
[0039] S302, a reinforcing layer is provided on one side of the target base paper layer.
[0040] The target base paper layer includes a first base paper layer and / or a second base paper layer with a preset number. The other side of the first base paper layer is in direct contact with the mouthpiece of the smoking product. The reinforcing layer has a mesh structure and contains a substance that forms hydrogen bonds with the cellulose.
[0041] After obtaining the first and second base paper layers, the target base paper layer to which the reinforcing layer needs to be added can be determined. This target base paper layer can be determined according to the actual situation, and this specification does not impose specific limitations on it. In one example, the first base paper layer and all second base paper layers except those in contact with the pattern layer can be used as the target base paper layer. In another example, only the first base paper layer can be used as the target base paper layer.
[0042] The method for preparing the reinforcing layer may involve obtaining a substance (such as a protein) that forms hydrogen bonds with cellulose, mixing the substance with other substances (such as nanocellulose, graphene, etc.), and then coating it onto the target base paper layer in a predetermined network structure to form the reinforcing layer.
[0043] In a preferred embodiment, the raw material ratio of the reinforcing layer may be: 30%-45% modified starch, 10%-15% carboxymethyl cellulose, 15%-25% soybean protein fiber, 5%-10% microfibrillated cellulose, 5%-12% crosslinking aid, 23%-35% functional filler, deionized water, etc.
[0044] Step S303: The first base paper layer and the second base paper layer are laminated together to obtain a tipping paper arranged around the mouthpiece.
[0045] Step S304: Printing and hot stamping are performed on the tipping paper to obtain a pattern layer, which contains a laser pattern.
[0046] Specifically, after setting the reinforcing layer, the first base paper layer and each of the second base paper layers can be laminated to obtain the tipping paper. The lamination method for the first and second base paper layers can be hot pressing, bonding, or other operations. After lamination, printing, hot stamping, or other operations can be used to obtain a patterned layer containing laser patterns.
[0047] Before laminating the first and second base paper layers, other substances can be filled into the grid of the reinforcing layer to improve the lamination performance of the laser transfer cigarette tipping paper. In one possible implementation, the method includes: filling the grid of the mesh structure with microcapsules, each microcapsule comprising a capsule shell and a capsule core, the capsule core containing a water-absorbing substance and / or an oil-absorbing substance, and the capsule wall containing a substance that forms hydrogen bonds with the cellulose.
[0048] To improve consumer experience, tobacco products may contain oil-soluble substances such as flavoring beads. These substances can cause the tipping paper to become wet. Furthermore, the water vapor inhaled by consumers when smoking cigarettes can also wet the cigarettes. Therefore, water-absorbing and / or oil-absorbing substances can be added to the mesh to extend the time that the tipping paper retains its shape by absorbing oil-soluble substances or water vapor.
[0049] Obviously, in addition to the first base paper layer, the second base paper layer, the reinforcing layer and the pattern layer mentioned above, the tipping paper can also be provided with a fragrance layer that can release fragrance, etc., as needed. This instruction manual does not make specific restrictions on this.
[0050] In the above embodiments, a reinforcing layer is provided in the target base paper layer. The reinforcing layer contains substances that form hydrogen bonds with the cellulose, so that the reinforcing layer can be firmly attached to the first base paper layer or the second base paper layer. In this way, when the laser transfer cigarette tipping paper is subjected to stress, the mesh structure of the reinforcing layer can improve the strength of the laser transfer cigarette tipping paper through hydrogen bonds, effectively preventing crack propagation and facilitating the maintenance of the appearance and structural integrity of the smoking product.
[0051] When the substance forming hydrogen bonds with cellulose in the reinforcing layer is a protein-based material, diffusion of the reinforcing layer onto the target base paper layer may occur during the application of the reinforcing layer. This can blur the mesh pattern and affect the consistency of laser transfer cigarette tipping paper across different batches or even the same batch. In one possible implementation, the reinforcement layer being applied to one side of the target base paper layer includes: The target base paper layer is pressed by a metal pressing roller to press out a mesh-like groove on one side of the target base paper layer; At a preset temperature, the groove is filled with a substance that forms hydrogen bonds with the cellulose to obtain the reinforcing layer.
[0052] Specifically, a mesh-like groove can be pressed into the target base paper layer using a metal pressing roller. The grooves are then filled with the material that constitutes the reinforcing layer to form the reinforcing layer. The shape of the grooves pressed by the metal pressing roller should be consistent with that of the reinforcing layer. This groove design prevents the diffusion of the reinforcing layer material onto the target base paper layer during the coating process, improving the stability of the reinforcing layer pattern and thus enhancing the consistency of the laser transfer cigarette tipping paper.
[0053] Furthermore, the temperature at which the material constituting the reinforcing layer is filled can be limited. This temperature should match the material constituting the reinforcing layer, as different compositions of the material require different temperatures. The temperature should be set to suppress diffusion. For example, when the material constituting the reinforcing layer contains protein-based substances, the temperature can be set to 4-8 degrees Celsius to suppress the diffusion of protein-based substances on the target base paper layer, further improving the stability of the reinforcing layer pattern.
[0054] Examples and Comparative Examples The embodiments of the present invention will be described in detail below with reference to examples. However, those skilled in the art will understand that the following examples are for illustrative purposes only and should not be considered as limiting the scope of the invention. Unless otherwise specified in the examples, conventional conditions or conditions recommended by the manufacturer are followed. Reagents or instruments whose manufacturers are not specified are all commercially available conventional products.
[0055] The laser transfer cigarette tipping paper of this application was prepared according to the requirements of the raw material composition and shape details of each layer of Examples 1-3 in Table 1. The comparative examples of laser transfer cigarette tipping paper were prepared according to the requirements of the raw material composition and shape of each layer of Comparative Examples 1-2 in Table 1.
[0056] Table 1. Relevant data for comparative examples and embodiments. The performance of the laser transfer cigarette tipping paper corresponding to the examples and comparative examples in Table 1 was tested using the indicators in Table 2, and the test results were obtained.
[0057] Table 2 Performance test results of comparative examples and embodiments As shown in Table 1, the difference between Example 1 and Example 2 is that Example 2 uses soybean protein fiber. As shown in Table 2, using soybean protein fiber helps improve the tensile strength of the packaging paper. As shown in Table 1, the difference between Example 2 and Example 3 is that some soybean protein fiber in Example 3 was replaced with nanocellulose. As shown in Table 2, nanocellulose helps improve the tensile strength of the packaging paper (tear index increased by about 50%). As shown in Table 1, the difference between Comparative Example 1 and Comparative Example 2 is that a reinforcing layer was added to Comparative Example 1. As shown in Table 2, adding a reinforcing layer helps improve the tensile strength of the packaging paper.
[0058] In summary, by incorporating a reinforcing layer into the target base paper layer, and by including substances in this reinforcing layer that form hydrogen bonds with the cellulose, the reinforcing layer can firmly adhere to the first or second base paper layer. Thus, when the laser transfer cigarette tipping paper is subjected to stress, the mesh-structured reinforcing layer can enhance the strength of the laser transfer cigarette tipping paper through hydrogen bonds, effectively preventing crack propagation and facilitating the maintenance of the appearance and structural integrity of the smoking product.
[0059] Unless otherwise specified, the raw materials and equipment used in this invention are all commonly used in the field; unless otherwise specified, the methods used in this invention are all conventional methods in the field.
