Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette film technology, and in particular to an invisible anti-counterfeiting cigarette film. Background Technology
[0002] In the tobacco packaging industry, cigarette film, as an important outer packaging material for cigarette products, needs to provide long-term protection against various external influences during transportation, storage, and sales, while also integrating reliable anti-counterfeiting functions to safeguard brand rights and market order. With the industry's increasing demands for packaging quality, invisible anti-counterfeiting cigarette film has gained widespread application due to its advantage of achieving efficient anti-counterfeiting without affecting the appearance. These films often employ a multi-layered composite structure design, achieving multiple functions such as protection and anti-counterfeiting through the complementary properties of different material layers. The choice of materials and the structural arrangement of each layer directly affect the overall performance.
[0003] However, existing invisible anti-counterfeiting cigarette films still have many technical problems to be solved in practical applications: First, their surface abrasion resistance is insufficient, and they are easily scratched by friction and abrasion during circulation, which not only affects the integrity of the appearance but may also weaken the protection of the internal structure; Second, the problem of static electricity accumulation is prominent, which easily attracts dust and impurities, leading to a decrease in the cleanliness of the cigarette pack, and may also interfere with the normal operation of automated packaging equipment, affecting packaging efficiency; Third, their moisture-proof and barrier properties need to be further strengthened, especially in humid environments, a single barrier layer is not enough to completely prevent water vapor penetration, which may cause cigarettes to become damp and deteriorate, shortening their shelf life. Utility Model Content
[0004] In view of the problems of insufficient surface abrasion resistance, prominent static electricity accumulation, and the need to strengthen the moisture-proof and barrier properties of the existing invisible anti-counterfeiting smoke film, this utility model is proposed.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] Reference Figures 1-3As shown, an invisible anti-counterfeiting cigarette film is provided, including a cigarette film body 1. The cigarette film body 1 includes a wear-resistant layer 2, an antistatic layer 3, a surface layer 4, a first barrier layer 5, a moisture-proof layer 6, an intermediate layer 7, a second barrier layer 8, a bottom layer 9, and a printing layer 10. The wear-resistant layer 2, antistatic layer 3, surface layer 4, first barrier layer 5, moisture-proof layer 6, intermediate layer 7, second barrier layer 8, bottom layer 9, and printing layer 10 are arranged sequentially. This allows each layer to work synergistically, comprehensively improving the protective and anti-counterfeiting performance of the cigarette film.
[0023] In this example, the wear-resistant layer 2 is made of modified polypropylene material with high hardness; it can effectively resist friction and scratches, protect the appearance and inner structure of the smoke film, and extend its service life.
[0024] In this example, the antistatic layer 3 is composed of a polypropylene copolymer with added antistatic agent; it can reduce static electricity accumulation, prevent dust adsorption, avoid interfering with packaging equipment, and ensure smooth packaging.
[0025] In this example, both the top layer 4 and the bottom layer 9 are copolymer PP layers; they have good flexibility and processing performance, which facilitates the bonding of the cigarette film to the shape of the cigarette pack and the composite processing of each layer.
[0026] In this example, both barrier layer 5 and barrier layer 8 are highly crystalline PP layers; they can form a dual barrier system that effectively blocks oxygen, water vapor and odors, extending the shelf life of cigarettes.
[0027] In this example, the moisture barrier 6 is made of polyethylene film material with excellent waterproof performance; it can enhance the ability to block water vapor, especially in humid environments, to prevent cigarettes from getting damp and deteriorating.
[0028] In this example, the intermediate layer 7, a homopolymer PP layer, provides solid support for the cigarette film structure, improves tensile strength and impact resistance, and prevents damage to the cigarette pack; the printed layer 10 is an invisible anti-counterfeiting layer, which can hide anti-counterfeiting information through special technology, achieve efficient anti-counterfeiting, and curb counterfeit and shoddy products.
[0029] The outermost wear-resistant layer 2 of this invisible anti-counterfeiting cigarette film is made of modified polypropylene material with high hardness. During the transportation and storage of cigarettes, it directly resists external friction and scratches, preventing scratches on the surface of the cigarette film and providing a physical barrier for the inner structure, thus extending the overall service life. The inner antistatic layer 3 reduces the accumulation of static electricity on the surface by adding antistatic agents, reducing the adsorption of dust and impurities, while avoiding interference of static electricity with automated packaging equipment and ensuring a smooth packaging process.
[0030] The copolymer PP layer of the top layer 4 and the bottom layer 9 has good flexibility, which allows the cigarette film to fit tightly to the shape of the cigarette pack and provides a stable foundation for the composite processing of each layer; the homopolymer PP layer of the middle layer 7 supports the entire structure with its own strength, improves the tensile and impact resistance of the cigarette film, and prevents the cigarette pack from being damaged during handling and stacking.
[0031] Barrier layer 5 and barrier layer 8, with their highly crystalline PP layers, form a double barrier, using their dense molecular structure to block the penetration of oxygen, water vapor, and odors. The polyethylene film of moisture-proof layer 6 acts as an additional barrier, further enhancing the barrier against water vapor. Especially in humid environments, it works together to maintain a dry environment for cigarette storage and extend shelf life.
[0032] The innermost printing layer 10 serves as an invisible anti-counterfeiting layer. It uses special fluorescent ink, 3D texture printing and other technologies to hide anti-counterfeiting information. It is invisible to the naked eye under normal light and can only be revealed by scanning with special equipment or a specific APP. This enables the anti-counterfeiting identification of cigarettes and curbs counterfeit products.
[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
