Tobacco Cigarette Inner Packaging Foil

 When most people think of cigarette packaging, the first thing that comes to mind is the brightly colored paper box. However, few people realize that the silvery film surrounding the cigarettes—the cigarette aluminum foil—is the "invisible guardian" of cigarette quality. It's not just part of the packaging; it's also a key material for maintaining the cigarette's flavor, protecting it from moisture, and preventing oxidation.

Three Core Applications of Aluminum Foil in Cigarettes

1. Inner Packaging

After opening a cigarette box, the aluminum foil directly covering the cigarettes (commonly called the "inner foil") is its most important application. It directly wraps the 20 cigarettes, acting like a "vacuum layer" in food packaging—isolating them from oxygen and moisture. Furthermore, this foil prevents odors from penetrating.

2. Liner

In addition to the inner foil directly covering the cigarettes, some cigarettes also have an additional layer of aluminum foil (called the "liner foil") applied to the inside of the paper box, providing a "double layer" of protection. The main function of this tobacco cigarette inner packaging foil is to improve the sealing of the paper box. Ordinary paper boxes have tiny pores, allowing trace amounts of air to seep in even after long-term storage. The lining foil fills these pores, further extending the shelf life of the cigarettes. Furthermore, the metallic texture of the aluminum foil enhances the packaging's premium feel, making the cigarettes appear more refined.

3. Extended Special Functions

With the diversification of cigarette packaging, aluminum foil has been given a variety of special functions. For example, some brands print brand logos or anti-counterfeiting patterns on the foil surface, which not only promotes the product but also prevents counterfeiting. Others feature "easy-tear" treatments to facilitate opening and enhance the user experience.

Alloy Selection

Not all aluminum alloys are suitable for cigarette foil. The industry standard is 1235 aluminum alloy. This alloy's popularity in cigarette packaging stems primarily from three key properties:

1. Excellent Ductility

Cigarette aluminum foil requires extremely high thickness, typically rolled into sheets as thin as 0.006-0.008 mm (approximately 1/10 the diameter of a human hair). This requires the aluminum alloy to possess exceptional ductility. 1235 aluminum alloy is a pure aluminum alloy (aluminum content ≥ 99.35%) with extremely low impurities and a uniform crystal structure. Through multiple cold rolling processes, it can easily achieve the required thinness without cracking or breaking.

2. Excellent Formability

Cigarette foil needs to tightly wrap around the cigarette and resist permanent wrinkles during folding and storage, which relies heavily on the alloy's formability. 1235 aluminum alloy possesses a moderate hardness, neither too soft to deform easily nor too hard to conform to the cigarette's contours. This makes it perfectly suited to automated cigarette packaging production processes—even at high speeds, the foil smoothly wraps around the cigarette, maintaining a smooth surface.

3. Stable Chemical Properties

Because the aluminum foil comes into direct contact with tobacco, its chemical properties must be stable to prevent it from reacting with tobacco components and affecting cigarette quality. 1235 embossed aluminum cigarette inner packaging foil contains no easily oxidized or easily precipitated metal elements (such as copper and magnesium). It remains stable at room temperature and, even with prolonged contact with tobacco, produces no harmful substances, meeting food-grade packaging safety standards.

Where to Buy Cigarette Packing Aluminum Foil

 The use of aluminum in the tobacco packaging industry is mainly the aluminum foil for the cigarette inner packaging. The cigarette packing aluminum foil can better prevent moisture and mildew, and keep dryness and taste. The thickness of the aluminum foil is 0.006mm to 0.007mm. Generally, aluminum foil with a thickness of 0.006mm is used. The temper is soft and has good extensibility.

Aluminum foil has very good protective properties. Aluminum foil paper cigarette boxes hardly absorb any aroma substances. Other materials such as metallized (coated) paper or printed paper cannot achieve similar quality and ability to protect aroma. In addition, aluminum foil paper used as the inner lining paper of cigarette packaging has good fluidity on the packaging machine, and can maintain high production efficiency.

1235 aluminum foil is a main kind of cigarette aluminum foil papers. Its aluminum content is not less than 99.35%. It has good anti-rust properties, formability, and weldability. It is also of few pinholes, low cost, good shape and stable chemical properties.

The alloy composition of 1235 aluminum foil and 8011 aluminum foil is different. The difference in process lies in the annealing temperature. The annealing temperature of 1235 aluminum foil is lower than that of 8011 aluminum foil, but the annealing time is basically the same. The tensile strength of 8011 aluminum foil is higher than that of 1235 aluminum foil. At the same time, the elongation of 8011 aluminum foil is not much different from that of 1235 aluminum foil, but slightly higher.

At present, the domestic production of 6~7μm light gauge aluminum foil generally uses 1235 aluminum, while European and American manufacturers generally use AA8079 alloy. Compared with AA1235 alloy, AA8079 alloy has higher content of Fe and Si, which has higher mechanical properties and higher production efficiency.

Difficult control of thickness error is a feature of aluminum foil rolling. The thickness difference of 3% is not difficult to control in the production of plates and strips, but it is more difficult to control in the production of aluminum foil.

As the thickness of the aluminum foil is thinned, many micro-conditions can be affected, such as temperature, oil film, oil and gas concentration, etc. The only way to adjust the thickness of aluminum foil is tension and speed. These factors have all caused the difficulty in thickness control of aluminum foil rolling.

The Quality Requirement of Cigarette Aluminum Foil Paper

The cigarette aluminum foil paper is used for cigarette packaging after lining paper, printing or paintings to prevent the cigarette from moisture and keep aroma. The common alloys of the cigarette foil are 1235 and 8079 with O temper. The thickness is 0.006-0.007 mm.

What are the advantages of aluminum foil? It is of strong air barrier performance, strong mechanical properties, high blast resistance, strong puncture and tear resistance, high temperature resistance (121℃), low temperature resistance (-50℃), oil resistance and good fragrance retention performance.

What are the quality requirements for cigarette aluminum foil? In the production process, the control of surface and performance mainly includes the following points:

1. Control the quality from the source and strictly inspect the blanks.

2. During the rolling process, the surface quality is controlled by the cleaning and roughness control of the rolls, the selection of rolling oil, reducing the viscosity of the rolling oil, and controlling the operating speed of the machine,etc.

3. During the slitting process, ensure that the edges of the aluminum coil are neat during slitting, and there should be no quality problems such as the curling edge.

4. In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the cigarette foil to ensure clean degreasing.
