Description

Technical Field

[0001] The utility model relates to the technical field of packaging films, and particularly relates to a self-fragrant cigarette packaging film. Background Technique

[0002] The tobacco industry has used a variety of materials on the outer packaging films of cigarette packs, including glassine paper, PVC coated film, PVDC coated film, BOPP cigarette film, etc. BOPP cigarette film has become the preferred material for cigarette packaging due to its excellent optical properties, wide heat-sealing range, high heat-sealing strength, strong water vapor barrier ability, uniform thickness, wide shrinkage rate regulation range, and good stiffness, which are incomparable to other materials.

[0003] Traditional cigarette packaging films have a three-layer structure. In humid southern regions, with high humidity, they cannot effectively block the penetration of water vapor, resulting in a shortened shelf life of cigarettes and poor fragrance emission effect, and a poor user experience. They cannot meet the requirements of cigarette enterprises as the end-users of cigarette films. Therefore, we propose a self-fragrant cigarette packaging film to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self-fragrant cigarette packaging film to solve the problems mentioned in the above background technique, such as high external humidity, inability to effectively block the penetration of water vapor, and poor fragrance emission effect.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A self-fragrant cigarette packaging film includes a base layer, and further includes: a self-fragrant layer is arranged directly above the base layer, a moisture-proof layer is arranged directly above the self-fragrant layer, a barrier layer is attached directly above the self-fragrant layer, and a heat-sealing layer is attached to the lower surface of the base layer.

[0006] Preferably, the material used for the base layer is biaxially oriented polypropylene.

[0007] Preferably, the material used for the moisture-proof layer is polyethylene.

[0008] Preferably, the self-fragrant layer is composed of a homopolypropylene and an anise solvent.

[0009] Preferably, the barrier layer is a PVDC coating, and an antistatic agent is added to the PVDC coating.

[0010] Preferably, the heat-sealing layer is linear low-density polyethylene, and the heat-sealing layer is in contact with the surface of the cigarette case.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The moisture-proof layer and the self-fragrance layer of the present utility model, in combination with the barrier layer, can achieve the moisture-proof effect of the cigarette box film, and the moisture-proof effect is relatively good. It also has a certain fragrance, which can enhance the user experience. The barrier layer is a PVDC coating, and an antistatic agent is added to the PVDC coating. The PVDC coating can prevent the penetration of gases, moisture, and odors, ensuring the dryness and quality of the cigarette sticks. At the same time, the added antistatic agent can endow the surface PVDC coating with antistatic function, preventing the adsorption of moisture and dust in the air due to static electricity, which is a factor causing the film to get damp. It can reduce static electricity accumulation, thereby reducing the risk of dampness and ensuring that the fragrance will not be affected by surface dust and water molecules.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0015] Please refer to Figure 1 , the present utility model provides a self-fragrant cigarette packaging film, which includes a base layer 1, and further includes: The material used for the base layer 1 is biaxially oriented polypropylene. Due to its excellent moisture barrier and optical properties, wide heat-sealing range, high heat-sealing strength, reasonable heat shrinkage rate, good stiffness and other advantages, it has become the preferred material for cigarette packaging. A self-fragrance layer 4 is provided directly above the base layer 1, a moisture-proof layer 2 is provided directly above the self-fragrance layer 4, and the material used for the moisture-proof layer 2 is polyethylene. This material has a certain moisture-proof performance, can further prevent the intrusion of moisture, and enhance the overall moisture-proof effect of the packaging film. The provided self-fragrance layer 4 is composed of homopolypropylene and anise solvent. The self-fragrance layer 4 can make the cigarette film emit an anise fragrance, improving the user experience. A barrier layer 3 is laminated directly above the self-fragrance layer 4. The barrier layer 3 is a PVDC coating, and an antistatic agent is added to the PVDC coating. The PVDC coating can prevent the penetration of gases, moisture, and odors, ensuring the dryness and quality of the cigarette sticks. At the same time, the added antistatic agent can endow the surface PVDC coating with antistatic function, preventing the adsorption of moisture and dust in the air due to static electricity, which is a factor causing the film to get damp. It can reduce static electricity accumulation, thereby reducing the risk of dampness. A heat-sealing layer 5 is laminated on the lower surface of the base layer 1. The heat-sealing layer 5 is linear low-density polyethylene. The heat-sealing layer 5 is in contact with the surface of the cigarette box. This layer is located on the bottom surface of the bottom layer and can shrink under heat, tightly wrapping the film body on the surface of the cigarette box, thereby enhancing the overall aesthetics of the packaged product and the user experience of consumers.

[0016] Working principle: First of all, the material used for the base layer 1 is biaxially oriented polypropylene, and the material used for the moisture-proof layer 2 is polyethylene. This material has a certain moisture-proof performance, which can prevent the intrusion of moisture to a certain extent and improve the overall moisture-proof effect of the packaging film. The self-fragrant layer 4 is composed of a homopolymer polypropylene and an anise solvent. The self-fragrant layer 4 can make the cigarette film emit an anise fragrance, improving the user experience. A barrier layer 3 is adhered above the self-fragrant layer 4. The barrier layer 3 is a PVDC coating, and an antistatic agent is added to the PVDC coating. The PVDC coating can prevent the penetration of gas, moisture and odor, ensuring the dryness and quality of the cigarette. At the same time, the added antistatic agent can endow the surface PVDC coating with antistatic function. Preventing the adsorption of moisture and dust in the air due to static electricity is a factor leading to film moisture absorption. It can reduce static electricity accumulation, thereby reducing the risk of moisture absorption and ensuring that the fragrance will not be affected by dust and water molecules.
