Tobacco film, also known as BOPP cigarette wrapping film, is a thin film essential in the packaging of tobacco products. It is composed of various functional polypropylene materials extruded and stretched into shape, playing a crucial role in protecting tobacco quality and enhancing brand image. This article provides a detailed explanation of what cigarette film entails.
Production Process of Cigarette Film:
Material Selection:
Raw materials such as polyethylene, polypropylene, and polyester are chosen based on their specific performance characteristics and usage requirements. YIREE selects high-quality raw materials to enhance the film’s strength, transparency, and heat-sealing properties.
Compounding and Mixing:
Raw materials and additives are mixed according to precise formulations, ensuring uniform distribution through mixing equipment.
Melt Extrusion:
The mixed materials are melted at high temperatures and extruded into sheets or film using an extrusion machine.
Cooling and Traction:
The extruded film undergoes rapid cooling and continuous traction to maintain flatness and continuity.
Stretching and Heat Setting:
The film is stretched to a certain degree and heat-set to stabilize its dimensions and relieve internal stresses.
Winding and Cutting:
The shaped film is wound using winding equipment and cut into various sizes as needed.
Characteristics of tobacco film:
- Lightweight and Flexible: Strong yet lightweight, easy to process and transport.
- High Transparency: Provides clear visibility of packaged products, enhancing visual appeal.
- Waterproof and Moisture-resistant: Effectively protects against moisture ingress, preserving product dryness and quality.
- Dust and Pollution Resistance: Guards against dust and external pollutants, maintaining product cleanliness.
- Strong Corrosion Resistance: Resistant to chemical corrosion, suitable for various environmental conditions.
- Impact and Friction Protection: Safeguards against impact and friction during transport, preserving cigarette integrity and quality.
Classification of Cigarette Film:
- Material-based Classification: Includes polyethylene, polypropylene, polyester cigarette films, among others.
- Application-based Classification: Such as packaging films, decorative films, and labeling films.
- Thickness-based Classification: Categorized into thin, medium, and thick cigarette films.
Cigarette Film Quality Control:
- Appearance Inspection: Checks for surface smoothness, bubbles, spots, and other defects.
- Thickness Measurement: Ensures compliance with manufacturing and customer standards.
- Performance Testing: Includes tensile strength, tear resistance, and heat-sealing strength tests to ensure suitability for use.
- Residue Testing: Ensures compliance with food safety standards by testing additives and auxiliary materials.
Tobacco Film Application Areas:
Primarily used in cigarette packaging to protect tobacco quality, prevent moisture and odor intrusion, and maintain dryness and hygiene. Also applied in food packaging to protect food quality, prevent moisture and odor intrusion, and maintain dryness and hygiene. Additionally, it is utilized in pharmaceuticals, cosmetics, and daily necessities packaging.
Conclusion:
Tobacco film, despite its seemingly modest appearance, plays an indispensable role in the tobacco industry. It serves not only as a guardian of cigarette quality but also as an enhancer of brand image. Advancing technology and evolving demands will drive cigarette film towards more eco-friendly and versatile solutions, enhancing consumer experiences with improved quality and reliability.
