In the cigarette packaging industry, aluminum foil is the main material to ensure the storage of the aroma of cigarettes, to be moisture-proof and antioxidant, and to maintain the stability of quality.
6-micron and 7-micron double zero aluminum foil is the main specification of the current cigarette packaging production line.
The difference in thickness between them is only 1 micrometer, but there are significant differences in terms of mechanical adaptability, barrier characteristics, production costs, good production speed, etc.
For packaging production lines with different production capacities and processes, choosing the right thickness of aluminum foil is the key to weighing product quality, production efficiency and production costs.
This article comprehensively compares the performance benefits and applicable scenarios of two aluminum foils to get accurate reference for the choice of cigarette companies.
In terms of basic performance and protective effect, the stability and protection of 7-micron aluminum foil are more advantageous.
The thickness of the aluminum foil directly determines the frequency of holes and blocking characteristics.
The thicker the thickness, the stronger the density of the material and the lower the permeability of oxygen and water vapor.
7-micron aluminum foil for cigarettes is mainly made of materials 8079 and 8011 of soft alloys.
After a complete anneling process, the internal structure is stable, there are very few hole defects, and the peeling strength and penetration strength meet the standard.
It can effectively insulate external moisture, oxygen and dust, block the original smell of tobacco for a long time and avoid cigarette moisture, string smell.
It deteriorates and adapts to long-term storage and long-distance transportation scenarios.
At the same time, it has better rigidity and strength, does not deform and break easily, and can effectively reduce the level of defects of finished products after packaging.
Being a lightweight, ultra-thin double-zero aluminum foil, 6 micron aluminum foil is the main choice for convenience, cost reduction and efficiency in the industry.
With a complex short-process casting and rolling technology, the 6-micron aluminum foil has reached extreme thinness.
The material is soft, the plasticity is extremely strong, and the fit is higher, which can perfectly meet the plastic requirements of soft packaging of the cigarette lining.
Compared to 7-micron aluminum foil, it consumes less raw materials and has obvious advantages in cost per square meter, which can effectively reduce the cost of packaging materials from companies.
However, limited by ultra-thin properties, the opening speed of 6-micrometer aluminum foil is relatively high, penetration strength and tensile strength are weak, and it is easy to break under conditions with high friction and crushing, and the requirements for the production environment and storage are more stringent.
As for the adaptability of the production line, the adaptation scenarios of two aluminum foils are very different.
The automatic high-speed cigarette packaging line imposes extremely high requirements on the flexibility, flatness and stability of materials.
The speed of work is fast, and the mechanical tension is excellent.
7 The mechanical properties of 7-micron aluminum foil are more stable, and the tensile and tear strength is stronger.
It is not easy to stretch, deform and break it when the material is at high speed.
There are very few problems, such as jamming, offset packaging and strict compaction.
Good product rate is higher.
It is suitable for automatic packaging production lines with medium, high speed and high capacity, especially suitable for the standards of hard cigarette boxes and high-quality cigarettes.
Mass production.
6-micron aluminum foil has a soft texture and excellent flexibility, which is better suited for production lines for medium and low speed packaging and individual production of cigarettes in soft packaging.
It has an excellent fit that can fit snugly to the inner wall of the cigarette wrapper, the packaging is flat, and the finished product has a delicate texture that fully meets the quality requirements of medium and low soft cigarettes.
However, when operating a high-speed production line, it is subject to stretching, bending and even damage under mechanical stress, which leads to a stop of production and a decrease in the speed of a good product, so it is not suitable for high-speed mass production scenarios.
In addition, the lightweight 6-micron aluminum foil can also slightly reduce the total weight of a pack of cigarettes, which is in line with the current trend of more environmentally friendly and low-carbon tobacco packaging.
Judging by the long-term production efficiency and the choice of the model, two aluminum foils have their own choice.
The main value of 7-micron aluminum foil lies in stability and high quality.
Although the cost of consumables is somewhat high, they have low production losses, low equipment failure rate and strong stability in the storage of finished products, which significantly reduces after-sales losses and processing costs.
It is suitable for high-quality cigarettes, export cigarettes and long-cycle warehouse goods.
This is the best choice for companies that primarily strive for quality.
The main advantages of 6-micron aluminum foil are economy and low weight.
With a scenario of moderate production capacity, a stable production environment and a short shipping cycle, it can maximize the compression of packaging costs while providing basic protection and adapting to large-scale production of popular affordable cigarettes.
Thus, there is no absolutely optimal specification of aluminum foil, but only the most suitable selection scheme for production lines.
For high-quality solid packaging, high-speed mass production and long-term warehouse quality, 7-micron aluminum foil is preferred; economical soft packaging, medium and slow production, cost control commitment and production lines for easy packaging, 6-micron aluminum foil is a cost-effective choice.
Companies can flexibly choose in combination with their own product positioning, production line parameters and inventory sales cycle to achieve an optimal balance between quality, efficiency and cost.
