Aluminum foil for bottle cap has the advantages of light weight, heat resistance, good conductivity,good printing effect, and recyclability. Therefore, aluminum foil is a common material for making bottle caps.
Aluminum packaging occupies an absolute dominant position in the world beverage packaging market. Especially in emerging economic powers such as Brazil, India, and China, there is still huge room for development in the use of aluminum alloys.
1xxx aluminum alloys like 1050, 1060, 1070 and 1100 can also be used for this application. It is a series with the most aluminum content, and its purity is above 99.0%. Because it does not contain other elements, the production process is relatively simple, and the price is relatively cheap. But for some aluminum caps with special requirements, the performance of the 1000 aluminum series may not meet the standard.
Aluminum bottle caps are mostly processed in a production line with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the material are very strict, otherwise cracks or creases will occur during processing.
In order to ensure the convenience of printing after the bottle cap is formed, the surface of the bottle cap material is required to be flat, without rolling marks, scratches and stains. The alloys generally used are 8011 aluminum foil. The general thickness is 0.20-0.23 mm and the width is 449-796mm.
3105 aluminum is a kind of Al-Mn alloy. On the basis of 3003 aluminum alloy, some Cu and Mg are added to increase the mechanical properties of the finished product. Therefore 3005 aluminum sheet has higher strength than 3003. The Carbonated drinks and beer bottle caps are usually made of 3105 aluminum foil sheet.
As for the color, gold aluminum fol roll is often used. It is mainly pre-coated with paint or pre-coated with DOS oil on the aluminum base material, mainly using sheet coating and roller coating processes. Sheet coating refers to DOS pretreatment first, and then sheet coating after cutting by cross-shearing. Roller coating refers to direct roll coating on the surface of aluminum base material after cleaning without DOS treatment.
