High Transparency and Glossiness: BOPP cigarette film has extremely high transparency, which can clearly display the exquisite patterns and colors of cigarette packaging, bringing consumers an intuitive visual enjoyment and enhancing the product's attractiveness. At the same time, its high glossiness gives the surface of the cigarette pack a bright texture, improving the overall grade of the cigarette and making it stand out on the shelf. For example, when light shines on cigarettes packaged with BOPP film, the film can highly reflect the light, making the cigarette pack shine and attracting consumers' attention.
Good Barrier Performance: It has a certain barrier function against odors and moisture. On the one hand, it effectively prevents the loss of cigarette aroma and maintains the unique flavor and quality of cigarettes; on the other hand, it resists the invasion of external moisture, avoids the cigarette being damp and moldy, and extends the shelf life of cigarettes. In the humid southern regions, BOPP cigarette film can provide reliable protection for cigarettes, ensuring that the cigarettes remain dry and have a pure taste in a high-humidity environment.
Excellent Mechanical Properties:
High Stiffness: During the packaging forming process, it can easily achieve high folding quality, ensuring that the cigarette pack has a regular and beautiful shape. Moreover, it can achieve a good heat-sealing effect in a short pause time, which is an important prerequisite for high-speed packaging. It is suitable for automatic variable-speed high-speed packaging machines, greatly improving production efficiency. In the automatic cigarette packaging line, BOPP cigarette film with high stiffness can smoothly pass through various packaging links, ensuring packaging speed and quality.
Strong Tear Resistance: It can withstand a certain degree of external pulling, friction and impact, protecting cigarette products from external damage during transportation and storage, and reducing product loss rate. Even in the case of rough handling, BOPP cigarette film can effectively protect the cigarettes in the cigarette pack and reduce cigarette damage caused by packaging breakage.
Appropriate Shrinkage Rate: It is generally divided into ordinary type and heat-shrinkable type. The heat shrinkage rate of ordinary cigarette film is controlled at 2%-5%, which is often used for soft packs of small cigarette boxes and carton packaging, ensuring the flatness and stability of the packaging. The heat shrinkage rate of heat-shrinkable cigarette film is more than 7%. After packaging, it can make the cigarette pack more compact and evenly wrapped, maintaining a tight state for a long time without loosening, showing excellent skin packaging effect. It is especially suitable for hard box cigarette packaging, overcoming the problem that ordinary cigarette film is easy to loosen and wrinkle on hard box packaging. For example, some high-end cigarette brands use heat-shrinkable BOPP cigarette film, which makes the cigarette pack packaging more delicate and fit, highlighting the product quality.
Good Heat-Sealing Performance: It has a wide range of heat-sealing temperatures, which can ensure stable operation on various cigarette packaging machines, adapt to the heat-sealing conditions of different packaging machines and the changes of heat-sealing temperatures in different environments. Whether in the cold winter workshop or the hot summer production environment, it can ensure the heat-sealing quality, avoid the occurrence of hot mouth wrinkles or loose sealing, and ensure the tightness and integrity of the packaging.
Antistatic Performance: During the cigarette packaging process, the static electricity generated by the film will seriously affect the cutting, conveying, folding and other processes, leading to machine operation failures. BOPP cigarette film effectively controls the generation of static electricity by adding antistatic agents reasonably, providing a guarantee for the smooth operation of the packaging machine. In dry seasons, the problem of static electricity is particularly prominent, and the good antistatic performance of BOPP cigarette film can ensure that the packaging process is not disturbed by static electricity, maintaining the normal operation of the production line.
Appropriate Friction Coefficient: The friction coefficient of the outer surface of the film against metal, especially the hot friction coefficient under high temperature conditions, is low, which can realize high-speed (400 packs/min - 600 packs/min) sliding in the hot state, meeting the full-speed operation needs of the packaging production line. At the same time, the friction coefficient between the other side of the film and the cigarette pack box paper is high, which is conducive to the good positioning of the cigarette pack and the film in the forming wheel, improving the folding quality and obtaining a compact packaging effect. For example, when the packaging machine is running at high speed, BOPP cigarette film can slide accurately on metal parts with the help of appropriate friction coefficient, and at the same time, it is closely attached to the cigarette box paper to complete high-quality packaging operations.
