Different Forms of Aluminum Bottle Cap Materials

1. Different Forms of Aluminum Bottle Cap Materials Abstract: There are different forms of aluminum bottle cap materials. There are rich alloys for different bottle cap closure:1060, 8011, 3105, 5052, 5182,etc. They can be used for can lid and bottle caps. 1060 and 8011 aluminum foil sheet There are two commonly used aluminum bottle cap materials: 8011 and 1060 alloy. What are their properties? Aluminum foil for bottle cap material is of washing grade A and has a low ear-making rate. Compared with plastic bottle caps, aluminum bottle caps not only have better performance, but are also low-cost, pollution-free, and recyclable, so they are favored by users.

2. Aluminum foil 8011 is a widely used bottle cap material on the market. The tempers are H14 and H16. The thickness range is 0.15-0.27mm, and the width range is 330-1000mm. It is suitable for liquor bottle caps, red wine bottle caps, cosmetic bottle caps, milk powder caps, medical caps, beverage caps, yogurt caps, etc. Because bottle cap materials have very strict quality requirements for aluminum sheet surface and shape. Therefore, during the hot rolling process, it is necessary to control product quality by controlling processing parameters, optimizing processes, and manual inspection. HaomeiAluminum has a control of the rolling passes of cold rolling and foil rolling according to the different blank width and the finished product thicknesses to ensure the finished plate surface and shape. To determine whether the 1060 aluminum plate is suitable for contact with food, you first need to understand the physical properties of the aluminum plate. 1060 aluminum plate has high strength and corrosion resistance, and is easy to process and form, so it is widely used in food packaging materials. In addition to physical properties, the chemical properties of aluminum plates also have a great influence on whether they are suitable for contact with food. The 1060 aluminum plate itself is a relatively stable metal material and will not react chemically in conventional food environments. However, if there is corrosion, oxidation and other phenomena on the surface of the aluminum plate, aluminum ions harmful to the human body may be released, thus causing food hazards. To evaluate whether 1060 aluminum sheets are suitable for food contact, processing technology factors need to be considered. The following is an introduction to several dimensions: 1. Choose high-quality raw materials to ensure compliance with food hygiene

3. requirements. 2. Use advanced production equipment and technology to ensure the surface smoothness of the aluminum plate and avoid scratches. 3. Use appropriate surface treatment techniques, such as polishing, sandblasting, etc., to improve the surface quality of the aluminum plate. 4. Use appropriate surface treatment techniques, such as polishing, sandblasting, etc., to improve the surface quality of the aluminum plate. 5. Strictly control the processing environment to prevent contamination and cross-contamination. 6. Detect and control the chemical composition and physical properties of aluminum plates to ensure compliance with food reliability requirements. 7. Only under the guarantee of the above-mentioned processing technology, 1060 aluminum can be reliably used in making bottle caps. Testing is one of the important means to ensure the reliability of aluminum plates in contact with food. The testing standards for 1060 alloy usually include aluminum ion release, heavy metal content, bacterial count and other indicators. Only aluminum plates that meet testing standards can be used in food packaging materials to ensure the reliability of contact between aluminum plates and food. Pre Cut Aluminum Sheet The beverage industry is one of the major contributors to the aluminum caps and closures market. Various types of aluminum caps are used in beverage packaging, such as crown caps, aluminum ROPP caps, high aluminum caps, pull-tab caps, lug caps, etc. Carbonated soft drinks, energy drinks and alcoholic beverages are the major end-user segments for aluminum caps and closures. The beverage industry is demanding more aluminum packaging. This demand has increased in recent years, particularly in categories such as ready-to-drink cocktails and imported beers. This growth can be attributed to increased consumer demand for sustainability, including the recycling benefits, convenience and innovation potential of

6. is directly related to the preservation effect and quality stability of the product. Through the sealing performance test, it is tested whether the aluminum foil sealing film can effectively seal food, medicine and other products under different sealing conditions. Printed Aluminum Sheet Aluminum bottle closure not only has good stamping performance and low anisotropy, but also has a certain baking strength after multiple color printing and curing. Aluminum alloy is used for bottle cap materials of wine, beverage and medical bottles. The printed aluminum sheet/coil is a main kind of aluminum bottle cap materials. Alloys of printed aluminum sheets 3105 aluminum plate belongs to the 3 series aluminum-manganese alloy. It has good anti-rust properties and good deep stamping effect. The strength, elongation and processing performance of the 3105 alloy meet the requirements of the automated high-intensity bottle cap production process, and no creases or rupture will appear during processing. Most cans on the market are made of aluminum alloy, and 3104 aluminum alloy is commonly used for the can body. 3104 aluminum alloy has unique advantages: on the one hand, it is stable in nature and does not easily react with the products it contains, ensuring the safety of food and beverages; on the other hand, 3104 aluminum is lighter, and the sealed containers made of it are lighter in weight, easier to transport, and save costs.

Among them, there is another aluminum alloy product that has the highest appearance rate in daily life—aluminum cap seal for cans. It can be used to make cans, beer caps, pull tabs, etc. Its thin thickness, high sealing performance, low production cost, and recyclability are the factors why aluminum bottle cap material is favored. Food packaged in aluminum cans tastes better than that packaged in plastic bottles. Taking the two types of sodas packaged as an example. When injected with the same proportion of carbon dioxide, plastic is more easily

8. "penetrated" by carbon dioxide than aluminum. Although the bottle seems to be sealed, carbon dioxide will still leak out of the bottle through some physical and chemical reactions. If a plastic bottle of soda is left in direct sunlight for twelve weeks, 15% of the carbon dioxide can be lost. The main alloys for pop cans are 3003, 3004, 5180 and 5052 aluminum sheet. Due to their high hardness, they are generally suitable for later slitting and stamping. In terms of manufacturing easy-open lids, 5052 alloy is used more, accounting for about 60% of the total, and the thickness is mostly 0.22~0.26mm. 5052 aluminum is used for beverage caps and food caps without internal pressure, and 5182 aluminum is used for beverage caps with internal pressure. In the production of cans, minimizing the thickness of the sheet, improving the elongation performance and strength of the product, improving material utilization and reducing production costs are the goals pursued by the can manufacturing industry.At present, the thickness of can cover materials is 0.27mm, 0.265mm, 0.26mm, 0.25mm, 0.24mm, and 0.22mm. As the thickness of can cover becomes thinner, higher requirements are placed on the mechanical properties of the aluminum sheets. 5052 aluminum alloy has good corrosion resistance, weldability, cold workability, and medium strength. Its surface is very bright after coating. It is widely used in the basic lid of functional drinks. The aluminum alloy 5052 aluminum plate used for can lids has a flat shape and precise thickness control, ensuring a thickness tolerance of ±0.005mm and ensuring stable post-processing. 5182 aluminum plate belongs to the Al-Mg series alloy and is widely used.
