Aluminum and aluminum alloy pp cap aluminum alloy is a new type of bottle cap sealing material, which not only has beautiful and generous features, but also has the function of preventing counterfeit goods. Therefore, aluminum has been widely used at home and abroad for sealed packaging of beverage bottles, wine bottles, cosmetic bottles, medicine bottles, etc.
1. Width and thickness tolerances are implemented according to the requirements of the process card
2. The surface is smooth, without cracks, bubbles, penetrating pores, metal and non-metal indentations, bright and dark streaks.
3. During the rolling process, check the surface quality at least once every 3 coils, and check the surface quality for each coil in the finished product pass.
4. Strictly control the quality of the slice to ensure that there are no burrs, knife back marks, and lotus leaf edges.
The commonly used pp cap aluminum alloy has a thickness range of 0.15mm-0.5mm, a width of 200-1500mm, a thickness tolerance of ± 0.005mm, and a width range tolerance of ± 1mm.
Why use aluminum foil for pp cap aluminum alloy? Relatively speaking, the shelf life of the product will be longer, because the aluminum foil has good oxidation resistance, which guarantees that the quality of the product will not be damaged. In addition, pp cap aluminum alloy has good corrosion resistance, especially after polishing. After the aluminum bottle cap, plus the later processing, the surface gloss and brightness are quite good. The surface requirements of pp cap aluminum alloy are also very high, and no black spots, oil stains and other stains can appear. Second, it has a stamping performance high standard.
