Matters needing attention in the production process of medicinal aluminum foil

　　【Aluminum China Net 】In daily life, the application of medicinal aluminum foil is very extensive and mature. The main uses of medicinal foil are blister packaging of medicine capsules and tablets, and bag-like packaging of powder granules and liquids. Because of its direct contact with edible drugs, the country has very strict requirements on the appearance and performance of medicinal foils.
　　
　　 There are two common medicinal foils on the market There are 8011 aluminum foil and 8021 aluminum foil. 8011 alloy generally has a thickness of less than 0.05mm, and 8021 alloy has a thickness of more than 0.05mm. Generally speaking, the main production process flow is: billet inspection-blooming rolling-opening and dividing rolling-coil rolling-finished rolled product-slitting-furnace annealing-finished product packaging. The surface of medicinal aluminum foil requires no greasy dirt, no shiny, no black lines, no pinholes, no maculas, no ruffles, etc. During the production process, the control of the surface and performance mainly includes several points:
　　
　　 One, first control from the source Quality, strict inspection of blanks;
　　
　　 2. Then in the rolling process , Control the surface quality through the cleaning and roughness control of the roll, the selection of the rolling oil, the reduction of the viscosity of the rolling oil and the control of the operating speed of the machine;
　　
　　 3. Again, in the cutting process During slitting, make sure that the edges of the aluminum coil are neat, and there should be no quality problems such as ruffles;
　　
　　 Fourth, the annealing process, According to the performance requirements of the medicated foil, the annealing time and annealing temperature are controlled to ensure clean degreasing.
　　
　　With the development of the pharmaceutical industry, The aluminum foil has excellent moisture resistance, barrier properties, drug resistance, chemical stability, and sanitation. The application ratio continues to rise, and the requirements for appearance and quality are getting higher and higher, and the market prospect is very broad.
