The production process of medicinal aluminum foil is a precise and strict process, mainly including raw material selection, surface treatment, rolling, annealing, coating addition, printing, cutting and finished product inspection. This process is particularly important in the field of pharmaceutical packaging, because it is related to the safety and effectiveness of drugs. In terms of raw material selection, the medicinal aluminum foil is made of aluminum alloy material with high purity and low iron content. These materials are carefully selected and rigorously tested to ensure good processability and physical properties.

In addition, these raw materials also have good chemical stability, which can ensure that there will be no adverse reactions with drugs during the drug packaging process. Surface treatment is one of the key links in the production process of aluminum foil. In the production process, the surface of the aluminum foil is treated by chemical or mechanical methods to improve its adhesion and printing performance. At the same time, the surface treatment also helps to enhance the corrosion resistance and oxidation resistance of the aluminum foil and extend its service life.

Rolling is the process of rolling aluminum foil raw materials to the required thickness. In the rolling process, it is necessary to control parameters such as temperature, pressure and speed to ensure the flatness and thickness of the aluminum foil. The annealing treatment is to eliminate the stress generated by the aluminum foil during the rolling process and improve the toughness of the material. By controlling the precise parameters of annealing temperature and time, the excellent performance of aluminum foil can be achieved. In addition, coating addition, printing and cutting may be involved in the production process. The coating is added to improve the barrier properties of the aluminum foil and protect the drug from the external environment. The printing process is used to print relevant information on the aluminum foil, such as drug name, specifications and instructions for use. The cutting link is to cut the aluminum foil into the appropriate size to meet the needs of different pharmaceutical packaging. Finished product inspection is the key link to ensure the quality of medicinal aluminum foil. Through strict inspection and testing, to ensure that each batch of aluminum foil meets the relevant standards and regulations.

In short, the production process of medicinal aluminum foil is a complex and delicate process, which requires strict control of the parameters and quality of each link to ensure product quality and safety.
