The Aluminium Jar Cap is a lightweight, smooth closure that seals a wide range of glass jars. Its smooth outer surface features markings that enhance grip, and its soft inner lining prevents leakage. It is available in a variety of sizes, including both food grade and non-food grade varieties.
The main alloy used to make this closure is called 8011, which possesses good deep drawing performance, low ear making rate, and certain strength after hardening. These features make it a more suitable material for the production of bottle caps. One of the biggest manufacturers of aluminium bottle caps is Haomei, which offers a full line of aluminum bottle caps, all of which feature superior quality.
Aluminum is a widely used material for bottle caps. Its resistance to oxidation makes it ideal for a variety of applications. It also forms a dense oxide film on its surface, protecting the physical properties of the product it is used for. It also seals tightly. As a result, it is widely used in many industries, and is ubiquitous in our daily lives.
