8011 Aluminum Foil for 28mm Aluminum Screw Cap

The earliest application of screw caps on beverages was on August 10, 1889, when Dan Rylands, a partner of Hope Glass Works, a well-known British bottle manufacturer, applied for a patent for screw caps, but at that time they were ultimately used mainly to store spirits. Screw caps have spiral grooves on the inside, which can be opened and sealed by rotating. They can be reused and do not require the use of tools when opening.

The most well-known modern screw cap is the Stelvin cap invented by Le Bouchage Mecanique in the 1960s and 1970s. This cap has a better airtightness, ensuring that the wine remains stable after long-term storage, and also solves the harm of TCA (trichloroanisole) pollution. 28mm aluminum screw cap is used for this use.

With the further development of social economy, aluminum screw caps are increasingly used in various industries of food packaging, such as beer, mineral water, bird's nest, coffee, beverages (including pre-mixed wine) and some high-temperature resistant products.

Products such as beer, bird's nest, coffee, and beverages often need to be sterilized at high temperatures. They have higher requirements for internal gaskets. First, they cannot be deformed by heat, and second, they cannot have any odor. These high-temperature resistant foods have higher requirements for internal gaskets. As a professional aluminum bottle cap material manufacturer, Haomei Aluminum provides different types of adhensive lacqures and granule gaskets like varnish, tpe, none-pvc,etc.

8011 aluminum alloy is mainly used in the packaging industry and has good oxidation resistance and corrosion resistance, while 8079 alloy is mainly used to make aluminum foil and has high strength and ductility. First, the chemical composition of 8011 alloy contains a higher proportion of aluminum, while 8079 alloy contains a higher proportion of silicon. This means that in some applications, such as packaging materials and food and drug packaging, 8011 aluminum foil for bottle cap may be more suitable because it has better ductility and plasticity.

Therefore, if you need aluminum foil with high strength and ductility, it is recommended to use 8079 alloy. However, if you need an economical aluminum foil and the requirements for strength and ductility are not particularly high, you can consider using 8011 aluminum foil . Of course, the specific choice should be weighed according to actual needs and budget.
