Description

Technical Field

[0001] The utility model relates to the technical field of cigarette film packaging, in particular to an antistatic and smooth cigarette film. Background Art

[0002] Cigarette film is a plastic film material used to package cigarettes. It has certain transparency, wear resistance and printing properties. Cigarette film is mainly used to package cigarettes. It can protect cigarettes from moisture and odor, while also maintaining the freshness and appearance of cigarettes. Cigarette film usually has certain stretchability and heat-sealing properties. Cigarettes can be packaged into a certain shape through a heat-sealing process, and can be printed on the surface to display brand logos, warnings and other information. In addition, while protecting the quality of cigarettes, cigarette film also plays a role in promoting the brand and enhancing the product image.

[0003] The surface of existing cigarette film is usually a plastic film, which is used to ensure surface smoothness and have a certain insulation effect. However, as the packaging speed increases, the temperature of the machine heat seal and the temperature of the beauty device rise rapidly, and the temperature of the packaging channel will also rise. This will cause the function of the plastic film on the surface of the cigarette film to be damaged and the protective ability to be reduced. Substances such as nicotine in tobacco leaves are easily affected by oxygen or light, thereby reducing the taste and shelf life of tobacco. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] In the description of the present utility model, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Reference Figure 1 The utility model provides an embodiment: an antistatic and smooth cigarette film, comprising a cigarette film body 1, an outer layer 2 is arranged on the outer surface of the cigarette film body 1, a barrier layer 3 is arranged inside the outer layer 2, an antistatic layer 4 is arranged inside the barrier layer 3, a sealing layer 5 is arranged inside the antistatic layer 4, and an antistatic layer 4 is arranged outside the innermost sealing layer 5. Since the inner layer of the cigarette film is more susceptible to static electricity during the packaging process, arranging the antistatic layer 4 as an inner layer can better prevent the generation and accumulation of static electricity, thereby reducing the adhesion between the cigarette film and the tobacco product and improving the packaging effect.

[0025] The outer layer 2 and the sealing layer 5 are both polyethylene layers, and the thickness of the outer layer 2 and the sealing layer 5 are both 20 μm. The polyethylene layer of the outer layer 2 has high flatness and has good printing performance and appearance effect. At the same time, the polyethylene layer has good heat-sealing performance. The use of polyethylene for both the inner and outer layers can ensure the heat-sealing effect of the cigarette film during the packaging process.

[0026] The barrier layer 3 includes a moisture-proof layer 31 and an aluminum layer 32. The moisture-proof layer 31 is connected to the outer layer 2, and the aluminum layer 32 is connected to the antistatic layer 4. The aluminum layer 32 is arranged inside the moisture-proof layer 31. The moisture-proof layer 31 is a polyamide film, and the thickness of the moisture-proof layer 31 is 10μm. The aluminum layer 32 is an aluminum evaporation film, and the thickness of the aluminum layer 32 is 10μm. The moisture-proof layer 31 is used to prevent moisture penetration, and the aluminum layer 32 can provide a shielding and blocking function of oxygen and light to prevent substances such as nicotine in tobacco leaves from being easily oxidized by oxygen or ultraviolet rays and visible light in the light from causing photochemical reactions in the chemicals in the tobacco and losing their aroma and taste. By blocking oxygen, the shelf life of tobacco products can be extended and the freshness and taste of tobacco can be maintained.

[0027] The antistatic layer 4 is a metallized polyester film with a thickness of 2-5 μm. The metallized polyester film is conductive and has good antistatic properties. It can reduce the problem of static electricity attraction to the cigarette film during production, processing, and packaging, which causes dust, fiber and other impurities to adhere to the surface of the cigarette film and affect the appearance quality. At the same time, it can avoid the problem that static electricity can cause adhesion between cigarette films or between cigarette films and tobacco products, affecting the packaging effect and increasing the difficulty of packaging.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
