Aluminum Ropp cap

The aluminum Ropp bottle cap is made of fine and special aluminum alloy material. It is mainly used for the packaging of liquor and beverage (including steam, non steam) and medical and health products, and can meet the special requirements of high temperature steaming and sterilization.




The aluminum bottle cap is mostly processed in a highly automated production line, so the strength, elongation and size deviation of the material are very strict, otherwise the fracture or crease will be produced in the processing. In order to ensure that the bottle cap is easy to print after forming, the flat surface, no roll marks, scratches and stains are required for the bottle capping material. The general alloy state is 8011 H14, 3003 H16 and so on. The general thickness of the material is 0.20mm to 0.23mm, and the width is 449mm to 796mm. The production of aluminum bottle cap material can be made by hot rolling billet or continuous casting and rolling, and rolled by cold rolling. At present, China's Ropp cover material production plant mostly uses continuous casting and continuous rolling billet, which is superior to cast rolling billet.


Related people in the industry, China's Ropp cap will grow at a rate of 10% per year. In 2010, there are about 15 billion burglar caps, 53 thousand and 500 to 60 thousand tons of aluminum strip, and the development is very rapid. The demand for aluminum bottle cap is increasing rapidly. At present, most of liquor, wine, medicinal liquor and beverage packaging in China are still broken glass bottles, and many bottle caps are made of aluminum. At present, there are tens of thousands of alcoholic drinks factories in China.
