Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cigarette paper, specifically, it relates to a color-changing cigarette tipping paper. Background Technology
[0002] As the tobacco industry increasingly demands product differentiation and enhanced consumer experience, the function of cigarette tipping paper has expanded from basic packaging to decorative and interactive features. Traditional color-changing tipping paper often relies on a single temperature- or humidity-sensitive material, but its color-changing effect is easily affected by fluctuations in ambient temperature and humidity. For example, ordinary inks are prone to fading or uneven color change in high-temperature or high-humidity environments, and the lack of an effective barrier layer design leads to unstable color-changing responses. Furthermore, traditional barrier materials have insufficient moisture barrier properties, further exacerbating the risk of color-changing function failure. Utility Model Content
[0003] In view of this, the technical problem to be solved by this utility model is to provide a color-changing cigarette tipping paper with precise protection through an aluminum foil barrier layer and a double layer of pearlescent ink, which not only isolates the interference of external moisture and temperature on color change, but also achieves dynamic color development through the double layer of pearlescent ink, thus solving the shortcomings of traditional cigarette paper that is susceptible to environmental factors.
[0004] To solve the above-mentioned technical problems, this utility model discloses a color-changing cigarette tipping paper, comprising a substrate layer, an aluminum foil barrier layer on the outside of the substrate layer, a pearlescent ink double layer on the outside of the aluminum foil barrier layer, the pearlescent ink double layer including a pearlescent base layer disposed on the outside of the aluminum foil barrier layer and a reinforcing color-changing layer disposed on the outside of the pearlescent base layer, a transition adhesive layer on the outside of the pearlescent ink double layer, a release layer on the outside of the transition adhesive layer, a microporous structure on the surface of the release layer, a silica film layer on the outside of the release layer, and a polypropylene film layer on the outside of the silica film layer.
[0005] According to one embodiment of the present invention, the thickness of the substrate layer is 10-15 μm.
[0006] According to one embodiment of the present invention, the thickness of the aluminum foil barrier layer is 5-10 μm.
[0007] According to one embodiment of the present invention, the aforementioned transition adhesive layer is an acrylic pressure-sensitive adhesive with a thickness of 2-8 μm.
[0008] Compared with the prior art, the present invention can achieve the following technical effects:
[0009] 1) Through the precise protection of the aluminum foil barrier layer and the pearlescent ink double layer, it not only isolates the interference of external moisture and temperature on color change, but also achieves dynamic color development through the pearlescent ink double layer, thus solving the shortcomings of traditional cigarette paper that is susceptible to environmental factors.
[0010] 1) Through the precise protection of the aluminum foil barrier layer and the pearlescent ink double layer, it not only isolates the interference of external moisture and temperature on color change, but also achieves dynamic color development through the pearlescent ink double layer, thus solving the shortcomings of traditional cigarette paper that is susceptible to environmental factors.
[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description

[0016] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.
[0017] Please refer to Figure 1 , Figure 1 This is a cross-sectional view of the color-changing cigarette tipping paper according to an embodiment of the present invention. As shown in the figure, a color-changing cigarette tipping paper includes a substrate layer 10, an aluminum foil barrier layer 20 on the outside of the substrate layer 10, and a pearlescent ink double layer 30 on the outside of the aluminum foil barrier layer 20. The pearlescent ink double layer 30 includes a pearlescent base layer 31 disposed on the outside of the aluminum foil barrier layer 20 and a reinforcing color-changing layer 32 disposed on the outside of the pearlescent base layer 31.
[0018] In one embodiment of this invention, the substrate layer 10 has a thickness of 10-15 μm. An aluminum foil barrier layer 20, with a thickness of 5-10 μm, is disposed on the outside of the substrate layer 10 to block external moisture and temperature interference. A pearlescent ink double layer 30 is disposed on the inside of the aluminum foil barrier layer 20. The aluminum foil barrier layer 20 better protects the pearlescent ink double layer 30, allowing it to better achieve its color development function.
[0019] Furthermore, the pearlescent ink double layer 30 includes a pearlescent base layer 31 disposed on the outside of the aluminum foil barrier layer 20 and a reinforced color-changing layer 32 disposed on the outside of the pearlescent base layer 31. The pearlescent ink double layer 30 is configured as a combination of the pearlescent base layer 31 and the reinforced color-changing layer 32, which not only retains the pearlescent texture, but also achieves better color rendering function through the reinforced color-changing layer 32.
[0020] Preferably, a transition adhesive layer 40 is provided on the outside of the pearlescent ink double layer 30, and a release layer 50 is provided on the outside of the transition adhesive layer 40, with a microporous structure on the surface of the release layer 50.
[0021] In detail, a transition adhesive layer 40 is provided on the outer side of the pearlescent ink double layer 30, and a release layer 50 is provided on the outer side of the transition adhesive layer 40. The transition adhesive layer 40 is an acrylic pressure-sensitive adhesive with a thickness of 2-8μm. The transition adhesive layer 40 enables a better and stronger bond between the pearlescent ink double layer 30 and the release layer 50. Then, a microporous structure is formed on the release layer 50 to shorten the color change response time and improve the overall effect.
[0022] Furthermore, a silica film layer 60 is provided on the outer side of the release layer 50, and a polypropylene film layer 70 is provided on the outer side of the silica film layer 60.
[0023] In detail, a silica film layer 60 is set on the outside of the release layer 50, which greatly improves the surface hardness. Furthermore, a polypropylene film layer 70 is set on the outside of the silica layer to avoid contamination and achieve waterproof and stain-proof functions.
[0024] In summary, this utility model, through the precise protection of the aluminum foil barrier layer 20 and the pearlescent ink double layer 30, not only isolates the interference of external moisture and temperature on color change, but also achieves dynamic color development through the pearlescent ink double layer 30, thus solving the shortcomings of traditional cigarette paper being susceptible to environmental factors.
