Description

Technical Field

[0001] This utility model relates to the field of tipping paper technology, specifically to a tipping paper with laser anti-counterfeiting markings. Background Technology

[0002] Tipping paper is typically used as the outer packaging paper for cigarette filters. It wraps the filter and connects the filter to the cigarette, while also decorating the filter and beautifying the cigarette.

[0003] Due to the high demand and profit margins of cigarettes, ensuring quality requires using only qualified materials. For tipping paper, manufacturers need to affix anti-counterfeiting marks during processing to guarantee its authenticity. Currently, the industry typically uses ink printing to print these marks. While this meets the requirement, factors such as drying time and ink pressure during printing can lead to blurring, cracking, and other defects affecting the clarity of the printed marks. Furthermore, environmental factors and the degradation of ink itself pose risks of fading and peeling, impacting the stability of the anti-counterfeiting measures and resulting in a short effective period. Moreover, since the anti-counterfeiting marks are printed with ink, there is a risk of toxic residue. For cigarettes that come into direct contact with the user's lips, the anti-counterfeiting marks printed on the outermost layer of the tipping paper are likely to come into contact with the user's lips, posing a potential safety hazard. In addition, for some cases where the anti-counterfeiting marks are more complex, the outlines of the printed anti-counterfeiting marks are prone to overlapping, which affects the recognition of the anti-counterfeiting marks. Therefore, the industry needs to provide an anti-counterfeiting mark that is secure, does not easily fade or peel off, and is easy to recognize. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, the aim is to provide a type of tipping paper with laser anti-counterfeiting markings. These markings are formed on the surface of the tipping paper using laser marking, without adding any substances during the process, thus enhancing security. Furthermore, the laser anti-counterfeiting markings are engraved onto the tipping paper, effectively preventing fading and peeling, resulting in better stability and meeting the requirements for long-term anti-counterfeiting. The resulting anti-counterfeiting markings also have clearer outlines, making them easier to identify and fulfilling the anti-counterfeiting requirements of tipping paper.

[0005] The specific technical solution is as follows: A type of tipping paper with laser anti-counterfeiting markings has the following characteristics: The tipping paper body layer has a double-layer structure, consisting of an upper tipping paper layer and a lower tipping paper layer stacked together. Furthermore, the upper tipping paper layer is equipped with a laser anti-counterfeiting mark. The anti-counterfeiting pattern layer is a colored base paper layer, which is placed between the upper tipping paper layer and the lower tipping paper layer. A heat insulation layer is disposed between the upper tipping paper layer and the lower tipping paper layer, and also between the anti-counterfeiting pattern layer and the lower tipping paper layer.

[0006] The aforementioned tipping paper with laser anti-counterfeiting mark further includes a hot stamping layer, which is disposed on the upper tipping paper layer and located on the side of the upper tipping paper layer opposite to the lower tipping paper layer, and is disposed next to the laser anti-counterfeiting mark.

[0007] The aforementioned type of tipping paper with laser anti-counterfeiting marking also includes a moisture-proof layer, which is disposed between the upper tipping paper layer and the lower tipping paper layer. At the same time, the moisture-proof layer is disposed between the heat insulation layer and the lower tipping paper layer.

[0008] The aforementioned type of cork paper with laser anti-counterfeiting markings, wherein the heat insulation layer is one or a combination of polyethylene (PE) film material and polyester (PET) film material.

[0009] The aforementioned type of tipping paper with laser anti-counterfeiting markings further includes an adhesive layer disposed between an upper tipping paper layer and a lower tipping paper layer. When the adhesive layer bonds the upper tipping paper layer and the lower tipping paper layer, it simultaneously bonds the anti-counterfeiting pattern layer and the heat insulation layer.

[0010] The aforementioned type of cork paper with laser anti-counterfeiting markings uses food-grade acrylic adhesive as the adhesive layer.

[0011] The aforementioned type of tipping paper with laser anti-counterfeiting mark further includes a protective layer disposed between the anti-counterfeiting pattern layer and the upper tipping paper layer, and the protective layer covers the laser anti-counterfeiting mark on the upper tipping paper layer.

[0012] The aforementioned type of tipping paper with laser anti-counterfeiting markings, wherein the color of the anti-counterfeiting pattern layer is obtained by dyeing with edible dyes.

[0013] The aforementioned type of tipping paper with laser anti-counterfeiting markings, wherein the laser anti-counterfeiting markings on the upper tipping paper layer are perforated holes, and the protective layer fills the perforated holes.

[0014] The positive effects of the above technical solution are: The aforementioned tipping paper with laser anti-counterfeiting markings features a double-layer structure consisting of an upper tipping paper layer and a lower tipping paper layer. A colored anti-counterfeiting pattern layer and a heat insulation layer are placed within the interlayer between the upper and lower tipping paper layers. The upper tipping paper layer has a laser anti-counterfeiting marking, and the heat insulation layer is positioned closer to the lower tipping paper layer. This allows the anti-counterfeiting pattern to be clearly visible through the laser anti-counterfeiting marking on the upper tipping paper layer, making it more prominent and easier to identify. Furthermore, the laser marking process reduces the addition of substances, improving security while ensuring clear outlines, preventing fading and peeling, and enhancing stability. This ensures long-term anti-counterfeiting performance, meeting the anti-counterfeiting requirements of tipping paper. Attached Figure Description

[0017] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 2 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0018] Figure 1 This is a cross-sectional view of an embodiment of the tipping paper with laser anti-counterfeiting markings according to this utility model. Figure 1 As shown, the tipping paper with laser anti-counterfeiting markings provided in this embodiment includes: tipping paper body layer 1, anti-counterfeiting pattern layer 2, and heat insulation layer 3.

[0019] Specifically, the tipping paper body layer 1 has a double-layer structure, including an upper tipping paper layer 11 and a lower tipping paper layer 12 stacked together. This allows for a space between the upper tipping paper layer 11 and the lower tipping paper layer 12 to form a sandwich layer, facilitating the concealed arrangement of the subsequent anti-counterfeiting pattern layer 2 and the heat insulation layer 3. This ensures that both the inner and outer layers of the tipping paper are made of tipping paper material, meeting the requirements of cigarette processing. Furthermore, a laser anti-counterfeiting mark 111 is provided on the upper tipping paper layer 1, ensuring that the laser anti-counterfeiting mark 111 is located on the outermost side of the tipping paper body layer 1, providing a condition for it to be visible to the user when the cigarette is formed.

[0020] Specifically, the anti-counterfeiting pattern layer 2 is a colored base paper layer, which provides the condition for the color to appear as a background color at the marked area after subsequent laser marking, making the anti-counterfeiting mark easier to identify. Furthermore, the anti-counterfeiting pattern layer 2 is positioned between the upper tipping paper layer 11 and the lower tipping paper layer 12, allowing it to form an interlayer within the tipping paper body layer 1. This ensures that its color is only revealed at the marked area after laser marking, while other areas are covered by the tipping paper body layer 1 itself, thus forming an easily identifiable anti-counterfeiting mark. Specifically, the heat insulation layer 3 is disposed between the upper tipping paper layer 11 and the lower tipping paper layer 12, achieving a hidden arrangement of the heat insulation layer 3 within the tipping paper body layer 1. When it is made into cigarettes, the heat insulation layer 3 will not directly contact the user's mouth, ensuring that the part in contact with the user's mouth is still tipping paper, thus guaranteeing safety and improving the tactile experience. Furthermore, the heat insulation layer 3 is disposed between the anti-counterfeiting pattern layer 2 and the lower tipping paper layer 12, ensuring that the large amount of heat generated during combustion during cigarette making is not excessively transferred to the outside during inhalation, thus protecting the anti-counterfeiting pattern layer 2. At the same time, when laser marking is performed on a finished product with the anti-counterfeiting pattern layer 2 and the heat insulation layer 3 already disposed within the tipping paper body layer 1, it can effectively prevent the risk of the heat generated by laser marking burning through the lower tipping paper layer 12, resulting in a more reasonable structural design.

[0021] Figure 2 This is a cross-sectional view of a tipping paper strip with laser anti-counterfeiting markings, after the hot stamping layer, moisture-proof layer, adhesive layer, and protective layer are applied. (See image.) Figure 1 and Figure 2As shown, a hot stamping layer 4 is also provided on the upper tipping paper layer 11. The hot stamping layer 4 is positioned on the side of the upper tipping paper layer 11 facing away from the lower tipping paper layer 12, ensuring that the hot stamping layer 4 is located on the outermost side of the tipping paper, resulting in a better decorative effect and making the cigarette appear more upscale. Furthermore, the hot stamping layer 4 is positioned next to the laser anti-counterfeiting mark 111, ensuring that there is no interference between the laser anti-counterfeiting mark 111 and the hot stamping layer 4. This allows both the laser anti-counterfeiting mark 111 and the hot stamping layer 4 to be fully displayed on the outer side of the tipping paper, facilitating observation and identification. It is worth noting that the hot stamping layer 4 is printed before the laser anti-counterfeiting mark 111 is processed, avoiding defects that might occur during the subsequent processing of the laser anti-counterfeiting mark 111 using laser marking equipment, thus ensuring that the hot stamping layer 4 can be successfully placed on the upper tipping paper layer 11.

[0022] More specifically, a moisture-proof layer 5 is provided between the upper tipping paper layer 11 and the lower tipping paper layer 12 to ensure that the tipping paper body layer 1 has a moisture-proof effect, enabling the cigarettes to be moisture-proof after rolling and improving their shelf life. At the same time, placing the moisture-proof layer 5 between the heat insulation layer 3 and the lower tipping paper layer 12 avoids interfering with the subsequent processing of the laser anti-counterfeiting mark 111, thus ensuring the quality of the processed tipping paper.

[0023] More specifically, the insulation layer 3 is made of polyethylene film, polyester film, or a combination thereof, which effectively meets the requirements for food-grade materials, ensuring safety and health. Furthermore, it can be directly coated onto the surface of paper using a film coating process, making processing easier and the technology more mature, thus reducing processing costs.

[0024] More specifically, an adhesive layer 6 is provided between the upper tipping paper layer 11 and the lower tipping paper layer 12. This adhesive layer 6 bonds the upper and lower tipping paper layers 11 and 12 together, forming a stable tipping paper body layer 1, which is then integrated and facilitates subsequent processing into cigarettes. Furthermore, when bonding the upper and lower tipping paper layers 11 and 12, the adhesive layer 6 also adheres to the anti-counterfeiting pattern layer 2 and the heat insulation layer 3, ensuring their stable arrangement within the tipping paper body layer 1 and guaranteeing the quality of the tipping paper. It is worth noting that adhesive layers 6 are provided between adjacent layers in the upper tipping paper layer 11, the anti-counterfeiting pattern layer 2, the heat insulation layer 3, and the lower tipping paper layer 12, ensuring the stability of adjacent layers and resulting in a more reliable and higher-quality tipping paper structure. Preferably, during the processing of the tipping paper, the upper tipping paper layer 11 is first laser-marked to directly form a laser anti-counterfeiting mark 111 on the upper tipping paper layer 11. Then, the heat insulation layer 3, the anti-counterfeiting pattern layer 2, and the upper tipping paper layer 11 are sequentially bonded to the lower tipping paper layer 12. This avoids the problem that the anti-counterfeiting pattern layer 2 is easily damaged when the laser anti-counterfeiting mark 111 is processed after the entire layer is bonded, thus ensuring the quality of the tipping paper.

[0025] More specifically, the adhesive used in the adhesive layer 6 is preferably food-grade acrylic glue, which not only meets the bonding requirements but also has the characteristics of being environmentally friendly and non-toxic, with good water resistance and temperature resistance, thus better meeting the bonding requirements of the tipping paper used in cigarette making.

[0026] More specifically, a protective layer 7 is provided between the anti-counterfeiting pattern layer 2 and the upper tipping paper layer 11. This protective layer 7 covers the laser anti-counterfeiting mark 111 on the upper tipping paper layer 11, preventing the anti-counterfeiting pattern layer 2, located below the upper tipping paper layer 11, from being directly exposed to the air at the laser anti-counterfeiting mark 111. This protects the anti-counterfeiting pattern layer 2 and reduces the risk of fading or peeling. It is worth noting that the protective layer 7 can be made of food-grade acrylic material, which is transparent, meeting the color display requirements of the anti-counterfeiting pattern layer 2. It can also act as an adhesive between the anti-counterfeiting pattern layer 2 and the upper tipping paper layer 11, resulting in a more rational structural design.

[0027] More specifically, the color of the anti-counterfeiting pattern layer 2 is obtained by dyeing with edible dyes. At this time, the edible dyes include, but are not limited to, natural pigments such as purple cabbage pigment, caramel pigment, and curcumin pigment, which can be selected individually or in combination. While meeting the dyeing requirements, they will not cause secondary pollution, have better safety, and will not cause harm to the user's body.

[0028] More specifically, the laser anti-counterfeiting mark 111 set on the upper tipping paper layer 11 is a perforated hole. Since the paper is relatively thin, it is easily penetrated during laser marking. If the marking were designed to prevent penetration of thin paper, the processing difficulty would be high. In this embodiment, setting the laser anti-counterfeiting mark 111 as a perforated hole effectively reduces the processing difficulty. Simultaneously, it facilitates the display of the colored anti-counterfeiting pattern layer 2, resulting in a more rational structural design. Furthermore, the protective layer 7 fills the perforated hole, allowing the laser anti-counterfeiting mark 111 on the upper tipping paper layer 11 to remain flat, thus facilitating subsequent cigarette rolling operations.

[0029] The tipping paper with laser anti-counterfeiting mark provided in this embodiment includes a tipping paper body layer 1, an anti-counterfeiting pattern layer 2, and a heat insulation layer 3. By setting the tipping paper body layer 1 into a double-layer structure including an upper tipping paper layer 11 and a lower tipping paper layer 12 stacked together, and setting a laser anti-counterfeiting mark 111 on the upper tipping paper layer 11, and arranging the colored anti-counterfeiting pattern layer 2 and the heat insulation layer 3 sequentially between the upper tipping paper layer 11 and the lower tipping paper layer 12 with the anti-counterfeiting pattern layer 2 close to the upper tipping paper layer 11, the anti-counterfeiting pattern layer 2 can be reflected through the laser anti-counterfeiting mark 111, highlighting the laser anti-counterfeiting mark 111. Furthermore, processing the laser anti-counterfeiting mark 111 by laser marking can reduce the addition of other substances, improve security, maintain the clarity of the outline of the laser anti-counterfeiting mark 111, avoid the problems of fading and peeling, improve stability, make it easier to identify, extend the display time of the anti-counterfeiting mark, and meet the long-term anti-counterfeiting requirements of tipping paper.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
