Coated aluminum bottle

Coated aluminum bottle
The use of film-coated aluminum bottle greatly simplifies the process, and the aluminum bottle has wide adaptability. It is also similar to the production method of two-piece bottles. The film-coated aluminum material is directly cupped, thinned and stretched into a bottle body, and then the required aluminum bottle is obtained through the thread of the bottle mouth, which completely saves the coating. There are many tedious processes in the aluminum bottle forming process. Due to the good corrosion resistance of the PET film used, it is basically suitable for packaging various beverages. It should be emphasized that there must be a strong bond between the PET film and the aluminum material in order to meet the mechanical requirements of the thinning and stretching of the aluminum material.
