Are Bottle Caps Aluminum

The main function of bottle caps is to seal bottles. In daily life, beer bottle caps, can caps, beverages, pharmaceutical packaging and other industries can be seen everywhere. Aluminum for bottle caps is inexpensive, easy to process and produce, and has diversified production.

Aluminum bottle caps have a large stretch length, so bottle cap material with better elongation need to be selected. Usually, the aluminum foils for bottle caps are 8011, 3003, 3105, 1060,etc. The aluminum foil of which alloy is selected according to the stretch length of different products.

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 aluminum bottle cap materials. 8011 color coated aluminum foil is a popular choice.

8011 aluminum foil is the main material for PP/ROPP bottle caps. It has good deep stamping performance and low earing rate; it has a certain strength after hardening, which is more in line with the requirements of bottle caps. The process of using 8011 aluminum foil for bottle caps is divided into casting and hot rolling.

8011-H18 aluminum bottle cap foil is mainly used for stamping shallow caps, and can be cast and rolled. 8011-H16 aluminum bottle cap foil is hot-rolled and is mainly used for aluminum pp caps. The thickness range is 0.15-0.27mm, thickness tolerance ±0.005mm, width range 330-1000mm and width tolerance ±1mm.

8011 H16 aluminum foil is used for medical and wine caps. There are still some subtle differences in the production process, because the tensile requirements of wine bottle caps are higher than those of medicinal bottle caps, so the annealing is also different.

8011 color coated aluminum foil is a product that coats other materials on the surface of aluminum foil to change its performance and use. The coating aluminum foil processing technology mainly includes material preparation,cutting, surface treatment, coating and drying.

1060 aluminum alloy is a method of making bottle caps that combine aluminum and plastic. It is industrial pure aluminum with an Al content of at least 99.6%. Its strength is suitable for stamping and forming processes. 1060-H24 aluminum sheet has the hardness and formability required for bottle caps. Since the aluminum-plastic combination will come into contact with the liquid in the bottle, most of them are used in the cosmetics industry, and some are used in the pharmaceutical industry.
