Cigarette Inner Liner Packaging Aluminum Foil

In the core of cigarette packaging, the aluminum foil inner liner carries a mission far exceeding mere “упаковка”—it is the guardian of the tobacco flavor and the last line of defense for product quality. With over a decade of experience in this field, our gold and silver cigarette inner liner packaging aluminum foil, produced with micron-level precision control and stringent performance standards, has become a stable partner for numerous tobacco companies.

From the very beginning of base material selection, we have established standards exceeding industry norms. We use high purity aluminum ingots with a purity of over 99.7%, rolled from a raw material with a more uniform metallic crystal structure, providing an excellent foundation for subsequent processing. After 18 rolling processes, the thickness of the finished aluminum foil is precisely controlled within the range of 6.5-7.5μm, with a deviation of no more than ±0.3μm. This precision not only ensures ease of shaping during packaging but also prevents sealing leaks caused by uneven thickness. Lightweight yet possessing excellent tear resistance and pressure resistance, these characteristics make the aluminum foil less prone to damage during production and packaging, enabling it to withstand complex environments such as high temperatures and high pressures, thus ensuring the integrity of the cigarette product.

Barrier performance is the core competitiveness of the inner aluminum foil lining, and our product has achieved a breakthrough improvement in this indicator. The oxygen permeability of the aluminum foil is controlled below 0.01 CM³/(м² · 24h · 0,1 МПа), and the water vapor permeability is below 0.02 г/(м² · 24 часа). This means that even in humid areas, it can effectively block external moisture intrusion, ensuring that the moisture content of tobacco leaves remains stable within the optimal range of 12%-15%. In a comparative test conducted last year by a tobacco company under high humidity conditions, cigarettes using our product showed a draw resistance change rate of only 2.1% after 3 months of storage, far exceeding the industry average of 5.3%.

The heat resistance and chemical stability are equally impressive. For the high-frequency heat-sealing process in cigarette production, we have optimized the алюминиевая фольга для сигарет surface treatment technology, increasing the heat-sealing strength to over 12N/15mm, with no delamination even after 5 repeated heat-sealing cycles. между тем, the product has passed stringent testing for food-contact aluminum foil, with heavy metal migration fully complying with GB 4806.9-2016 standards. The content of harmful elements such as lead and cadmium is below 0.001 mg/kg, preventing flavor contamination at the source.

From a production process perspective, we employ advanced aluminum foil production technology to ensure the quality stability of each roll. Our production line is equipped with internationally leading equipment and operates strictly according to the ISO9001 quality management system, ensuring that every step meets the highest standards. This rigorous production process not only improves product quality but also provides assurance for our customers’ производство.

We have also given full consideration to the details of the user experience. The aluminum foil surface undergoes a special passivation treatment, with the coefficient of friction controlled between 0.25 а также 0.30. This ensures smooth feeding during high-speed packaging machine operation while providing consumers with a pleasant tactile experience when opening the package. This design, which balances industrial production and end-user experience, is the result of our years of in-depth cooperation with tobacco companies.

Our cigarette inner liner packaging aluminum foil has become a leader in the industry due to its superior barrier properties, excellent mechanical properties, outstanding printability, экологичность, and rigorous production processes. For us, each roll of inner liner packaging aluminum foil embodies a commitment to quality. From 26 testing steps from raw materials to finished products, and from comprehensive upgrades in production processes to environmental standards, we always prioritize the needs of tobacco companies, using our technological strength to safeguard the authentic flavor of every cigarette.
