Pharmaceutical aluminum foil is widely and maturely used in our daily life. The main uses of pharmaceutical foil are blister packaging for pharmaceutical capsules and tablets, as well as bag packaging for powder granules and aqueous agents. Because of its direct contact with edible pharmaceuticals, the national requirements for pharmaceutical foil are very strict in terms of appearance and performance.
The common pharmaceutical foils in the market are 8011 aluminum foil, 8021 aluminum foil and 8079 aluminum foil, which can be used for ptp foil, cold-formed pharmaceutical foil, tropical type blister packaging, child-safe pharmaceutical packaging, pharmaceutical bottle caps, etc.
As aluminum foil for pharmaceuticals manufacturer, our the main production process is: billet inspection - open billet rolling - open medium split rolling - combined roll rolling - rolled finished product - slitting - furnace annealing - finished product packaging. The surface of pharmaceutical aluminum foil requires no oil, no bright crystals, no black lines, no pinholes, no yellow spots, no ruffles, etc. In the production process, for the control of the surface and performance, the main points are as follows.
First, first of all, we must control the quality from the source, strict inspection of the blank;
Second, then in the rolling process, through the cleaning of the rolls and roughness control, the choice of rolling oil, reduce the viscosity of the rolling oil and control the machine running speed to control the surface quality;
Third, again, in the slitting process, to ensure that the slitting of aluminum coil edge part of the neat, can not appear ruffled edge and other quality problems;
Finally, in the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the pharmaceutical foil to ensure clean oil removal.
With the development of pharmaceutical industry, pharmaceutical aluminum foil, with its excellent moisture resistance, barrier, drug resistance, chemical stability, and hygiene, the application ratio is rising, and the appearance and quality requirements are getting higher and higher, and the market prospect is broad.
