Four precautions for the production process of pharma foil

Edit:Mingtai Date: 2019-08-13 13:21
https://www.aluminumsheet-manufacturer.comIn our daily life, the application of pharma aluminum foil is very extensive and mature. The main uses of pharma foil are blister packaging of pharmaceutical capsules and tablets, as well as bag-like packaging of powder granules and water. Due to its direct contact with foodstuffs, the state has strict requirements on the appearance and performance requirements of the foil.
The common pharma foils on the market have two alloy states, namely 8011 aluminum foil and 8021 aluminum foil, wherein the 8011 alloy state generally has a thickness of 0.05 mm or less, and the 8021 alloy state has a thickness of 0.05 mm or more. In general, the main production process is: blank inspection - blank rolling - open medium rolling - rolling rolling - rolling finished - slitting - furnace annealing - finished packaging.
The surface of pharma aluminum foil requires no oil stain, no bright crystal, no black line, no pinhole, no yellow spot, no fringe, etc. In the production process, the control of surface and performance is mainly a few points:
First, we must first control the quality from the source and strictly test the blanks;
Second, in the rolling process, the surface quality is controlled by the cleaning of the rolls and the control of the roughness, the selection of the rolling oil, the reduction of the viscosity of the rolling oil and the control of the running speed of the machine;
Third, again, in the process of slitting, it is necessary to ensure that the edge of the aluminum coil is neatly trimmed during slitting, and that quality problems such as ruffles cannot occur;
Fourth, in the annealing process, according to the performance requirements of the foil to control the annealing time and annealing temperature to ensure clean oil.
With the development of the pharmaceutical industry, pharma aluminum foils have excellent moisture resistance, barrier properties, chemical resistance, chemical stability, hygiene, application ratios, and appearance and quality requirements are increasing. The prospects are very broad.
