Medicinal Aluminum Foil Production Process

- Nov 06, 2019-

In daily life, the application of medicinal aluminum foil is very extensive and mature. The main uses of medicine foil are foams of medicine capsules, tablets, etc.

 

Cover packaging and bag packaging of powder granules and water. The country’s appearance on the foil due to its direct contact with the food product

 

And performance requirements are very strict.

There are two kinds of medicine foils commonly used in the market, such as 8011 aluminum foil and 8021 aluminum foil, of which 8011 alloys are generally thick in thickness.

 

Below 0.05 mm, the 8021 alloy has a thickness of 0.05 mm or more. In general, the main production process is: blank inspection

 

Inspection - blank rolling - open medium rolling - rolling rolling - rolling finished products - slitting - furnace annealing - finished packaging. The surface of medicinal aluminum foil is required to be free of oil,

 

No bright crystal, no black lines, no pinholes, no yellow spots, no fringes, etc., in the production process, for the control of surface and performance,

 

Mainly for a few points:

1. First of all, we must control the quality from the source and strictly check the blanks;

2. Then, during the rolling process, through the cleaning of the rolls and the control of the roughness, the selection of the rolling oil, and the reduction of the rolling

 

Control the surface quality by controlling the viscosity of the oil and controlling the running speed of the machine;

3. Again, during the slitting process, it is necessary to ensure that the edge of the aluminum coil is neatly trimmed during the slitting process, and that the quality of the ruffles cannot occur.

 

question;

4. Finally, in the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the foil to ensure degreasing.

 

clean.

With the development of the pharmaceutical industry, medicinal aluminum foil has excellent moisture resistance, barrier property, chemical resistance and chemical stability.

 

Hygienic, the proportion of applications is rising, the appearance and quality requirements are getting higher and higher, and the market prospect is very broad.
