With the increasing demand for the quality of pharmaceutical aluminum foil, now most of the high-grade drugs use cold-formed pharmaceutical foil, among which 8021 aluminum foil is the most common one.
The requirement of the pharmaceutical foil is high, which includes a flatness without scratching, spots, color difference, bumpy spots, and voids. The rolling of the foil will have a large influence on its quality which should be strictly controlled.
The uniformity of the single roll and the precision of the paired roll should be controlled within 0.01μm, and the difference of the roll diameter of the finishing roll should be within 0.01mm; meanwhile, low viscosity oil is adopted for its higher volatility. The oil film between the two layers of aluminum foil is thinner and more uniform. The lubrication performance is low to increase the friction between to foils to prevent them from sliding, which will make the color more uniform to prohibit flash points and color difference.
Mingtai strictly controls its production process, the thickness range of its 8021-O aluminum foil is within 0.018mm-0.2mm, the precision can be controlled within 100-1650mm according to the customization. 8021 foil features high blast, puncture and tear resistance, excellent moisture-proof, light-shielding. It has a clean and uniform surface with no pinholes or spots.
Mingtai has been committed to the production and sales of aluminum alloy products.
