The production process of 1235 Aluminum Foil
First of all, I will introduce the production process of 1235 Aluminum Foil to you who are reading, and take you to understand the multiple processes it goes through.
First, our factory must prepare raw materials. The primary raw material for making 1235 aluminum alloy foil is high-purity aluminum billet. These aluminum billets can be obtained through two methods: one is to smelt aluminum metal through alumina reduction; the other is to recycle and remelt scrap aluminum products to obtain aluminum metal. Next, we will put the prepared aluminum billet into the smelting furnace for smelting. Generally, electrolytic furnaces or molten salt furnaces are used to smelt aluminum. A certain proportion of alloying elements, such as silicon, copper, zinc, etc., are added during smelting. These alloying elements can change the properties of aluminum and improve the strength and corrosion resistance of alloy foils. Then workshop workers will cast the smelted aluminum liquid through the continuous casting machine, and pour the liquid aluminum into the crystallizer of the continuous casting machine. The cooling water in the crystallizer causes the liquid aluminum to quickly solidify into an aluminum billet. The thickness of the aluminum billet is determined according to the required thickness of the aluminum alloy foil. After continuous casting, the aluminum billet is rolled up tightly by a steel winding machine and stretched by a tractor to maintain the consistency and flatness of the alloy foil. After passing through the continuous casting process, the aluminum billet also undergoes heating and homogenization treatment through multi-pass billet controlled rolling. The purpose of this step is to eliminate the stress inside the aluminum billet, improve the plasticity of the material, and prepare for the subsequent rolling process.
Then the workshop master will perform three rolling processes on the aluminum billet. The aluminum billet that has been heated and homogenized must first enter the rough rolling mill for rough rolling, which is one of the key links in alloy foil preparation. Rough rolling is to gradually roll the aluminum billet into the required alloy foil thickness through multi-pass rolling. It also provides good process conditions for the next rolling process. After rough rolling, the alloy foil enters the intermediate rolling mill for intermediate rolling. Intermediate rolling is to further reduce the thickness of the alloy foil through multi-pass roller rolling to form a more uniform foil. After intermediate rolling, further finishing rolling operations are required. Finish rolling is to further reduce the thickness of the alloy foil to the required size through multi-pass roller rolling. Finish rolling requires a more stringent rolling process to ensure the dimensional accuracy and surface quality of the alloy foil. These three processes are the most important part of controlling the thickness of aluminum foil. They are not only more cost investment in the processing process, but also satisfy customers' guarantee of aluminum foil quality.
After multiple passes of rolling, the alloy foil will be subject to strong stress and needs to be annealed. Annealing is to heat the rolled alloy foil to a certain temperature, then maintain it at a constant temperature for a period of time, and then gradually cool it. Annealing can eliminate the stress inside the foil and improve the deformation performance of the alloy foil. The annealed alloy foil undergoes surface treatment. Surface treatment includes cleaning and chemical treatments. Cleaning can remove oil stains and impurities on the surface of alloy foil, making it cleaner. For chemical treatment, we will use pickling and alkali cleaning to improve the surface finish and corrosion resistance of the alloy foil.
Finally, the surface-treated 1235 alloy foil will be cut into the width required by the customer, and the alloy foil will be rolled into a roll through a coiler. The rolled alloy foil can be further processed by consumers, such as cutting into sheets of required size or rolling into rolls for packaging.

There may be many consumers who are worried about the barrier properties of 1235 alloy aluminum foil. As a high-performance packaging material, 6-micron 1235 alloy aluminum foil definitely possesses barrier performance benefits. We believe that cigarette packaging built of this aluminum foil can successfully safeguard the quality of chopped tobacco while also improving consumer product quality.
Aluminum foil has significant gas barrier qualities, allowing it to efficiently prevent oxygen, moisture, carbon dioxide, and other gas molecules from penetrating. This cigarette package feature helps to preserve the quality of cut tobacco during storage and transportation by protecting it from moisture, mildew, and oxidation while retaining its natural taste and scent. Second, aluminum foil 1235 alloy 6 micron thick has a strong tensile strength and wear resistance. This implies that when aluminum foil is packaged into cigarettes, it can sustain a certain amount of process pressure and is not easily destroyed.At the same time, during use by our consumers, aluminum foil has good durability and can ensure that the packaging remains intact after being opened and closed multiple times. Thirdly, 1235 alloy 6 micron aluminum foil also has excellent corrosion resistance. In cigarette packaging, the surface and internal structure of aluminum foil are stable and not easily affected by the external environment. Even in high temperature, high humidity or other harsh environments, it can still maintain its barrier properties to ensure that the quality of cut tobacco is not damaged. 1235 alloy 6 micron aluminum foil has good heat sealing properties. In the cigarette packaging production process, aluminum foil can be perfectly combined with various heat sealing materials (such as polyethylene, polypropylene, etc.) to form a tight sealing layer. This helps ensure that the cigarette package maintains good sealing performance under high temperature conditions, thereby reducing the probability of oxygen and moisture entering the interior of the package.
It is worth mentioning that 1235 alloy 6 micron aluminum foil adopts advanced coating technology during the production process of our factory, giving it a better barrier effect. Coating materials are generally polymer resins, such as polyurethane, polypropylene, etc. These coatings can enhance the air, water and oil tightness of aluminum foil, further reducing the penetration of substances such as gases, liquids and grease.
From the perspective of safety and health, this is also a matter of concern to most of us as consumers. Cigarette packaging made of 1235 alloy 6 microns aluminum foil can ensure product safety and hygiene and prevent cigarettes from being contaminated and spoiled.
