Precautions for the production of medicinal aluminum foil
In daily life, the application of medicinal aluminum foil is very extensive and mature, the main use of medicinal foil medicine capsules, tablets and other blister packaging and powder particles, water bag-like packaging. Because of its direct contact with edible drugs, so the state of the appearance and performance requirements of the foil is very strict.
Commonly on the market there are two kinds of foil, 8011 aluminum foil and 8021 aluminum foil, 8011 alloy which are generally the thickness of 0.05mm below 8021 alloy thickness is more than 0.05mm. In general, the main production process is: blank inspection - open blank rolling - open in the rolling - roll - rolling finished - cutting - furnace annealing - finished packaging. There are no oil on the surface of the medicinal aluminum foil, no bright, no black line, no pinhole, no macular, no lotus leaf, etc. In the production process, for the surface and performance control, mainly for a few points:
First, the first from the source to control the quality, strict inspection billet;
Second, and then in the rolling process, through the roller cleaning and roughness control, rolling oil selection, reduce the viscosity of rolling oil and control the operation speed of the machine and other aspects to control the surface quality;
Third, again, in the cutting process, to ensure that the edge of aluminum when the edge of the neat part, can not appear lotus leaf and other quality problems;
Fourth, the final in the annealing process, according to the performance requirements of the foil to control the annealing time and annealing temperature, to ensure that the oil clean.
With the development of the pharmaceutical industry, medicinal aluminum foil with its excellent moisture resistance, barrier, chemical resistance, chemical stability, health, the proportion of rising applications, appearance and quality requirements are also increasing, the market The prospect is very broad.
