8079 pharmaceutical grade packaging aluminum foil


8079 pharmaceutical packaging aluminum foil is main used as the blister packaging of medicine capsules and tablets, as well as bag packaging of powder granules and water. Due to its direct contact with medicine, the requirements on the appearance and performance requirements of the pharmaceutical grade aluminum foil are strict. The common pharmaceutical packaging aluminum foil on the market has a thickness of less than 0.05 mm.

8079 pharmaceutical packaging aluminum foil

In general, the main production process of pharmaceutical packaging aluminum foil is: blank inspection - blank rolling - open rolling - roll rolling - rolling finished - slitting - furnace annealing - finished packaging. The surface of pharmaceutical grade 8079 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 about the a few points as follows:
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, 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 pharmaceutical packaging aluminum foil to control the annealing time and annealing temperature to ensure clean oil.

With the development of the pharmaceutical industry, 8079 pharmaceutical packaging aluminum foil have excellent moisture resistance, barrier properties, chemical resistance, chemical stability, hygiene, application ratios, and appearance and quality requirements are increasing.
