What Is The Raw Material of Aluminium Caps for Bottles

Bottle caps are essential for sealing various containers. Food and beverages can therefore be optimally protected throughout their shelf life. In addition to having good deep stamping and forming properties, and low anisotropy, aluminum alloy bottle cap materials also have a certain baking strength after multiple color printing and curing.

3105 aluminum sheet belongs to 3 series aluminum-manganese alloy, which has good anti-rust performance and good deep drawing effect. The strength, elongation and processing performance of the material meet the requirements of the bottle cap production process with high automation intensity, and there will be no creases or cracks during processing. When the bottle cap is used to package carbonated beverages, 3105 alloy must be used. 3105 aluminium color coated sheet is a popular choice.

1060 aluminum strip is commonly used in the food packaging industry, such as beverage cans, edible oil cans, etc. Its non-toxic, odorless and pollution-free properties make it an ideal choice for food packaging.

Testing is one of the important means to ensure the reliability of aluminum plates in contact with food. The testing standards for 1060 aluminum plates 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.

The main elements of 8011 aluminum foil are Al-Fe-Si, and the rest are trace impurity elements. Its performance is better than pure aluminum foil. 8011 aluminum plate is not commonly used, but 8011 aluminum foil is widely used, especially in the field of bottle cap materials.

8011 aluminum foil is the main material for PP/ROPP bottle caps. It has good deep drawing performance and low ear-making rate; it has a certain strength after work hardening, which is more in line with the requirements of bottle caps.

The main raw and auxiliary materials of Haomei Aluminum’s colored foil sheets for food are all internationally renowned brands: the cleaning agent is imported from Henkel of Germany; the coating is PPG, VALSPAR, ICI food-grade epoxy resin; the spray wax is edible petroleum jelly (white wax) imported from the United States to ensure food safety.

The aluminum foil for bottle cap is first rolled and then wave-cut, which ensures that the cleaning is in place, the coating is uniform, the film thickness is consistent, and the loss and waste are reduced. It has passed many quality and safety certifications, such as European REACH regulations, US FDA certification, and Chinese GB 4806.1 standards, ensuring its safety to human health.
