PBlister Tablets Capsules Pharmacuetical Packaging Aluminum foil
In daily life, the application of medicinal aluminum foil is very extensive and mature. The main uses of medicinal foil are blister packaging of pharmaceutical capsules, tablets, etc., and bag packaging of powder granules and water.
Because of its direct contact with edible drugs, the country has strict requirements on the appearance and performance of medical foils.
There are two common types of medicine foils on the market, 8011 aluminum foil and 8021 aluminum foil. The thickness of 8011 alloy is generally below 0.05mm, and the thickness of 8021 alloy is above 0.05mm.
Generally speaking, the main production process is: billet inspection-open billet rolling-open middle split rolling-coiled rolling-rolled products-slitting-furnace annealing-finished product packaging.
The surface of medicinal aluminum foil requires no oil stains, no glitter, no black lines, no pinholes, no yellow spots, no lotus leaf edges, etc. During the production process, the surface and performance must be controlled.
The main points are:
First, we must first control the quality from the source and strictly inspect the blanks;
Second, then in the rolling process, control the surface quality through the cleaning and roughness control of the rolls, the selection of rolling oil, reducing the viscosity of the rolling oil, and controlling the speed of the machine;
Third, again, during the cutting process, it is necessary to ensure that the edge of the aluminum coil is neat when cutting, and quality problems such as lotus leaf edges cannot occur;
Fourth, in the annealing process, according to the performance requirements of the drug foil, the annealing time and annealing temperature are controlled to ensure clean oil removal.
With the development of the pharmaceutical industry, medicinal aluminum foils have excellent moisture resistance, barrier properties, chemical resistance, chemical stability, hygiene, application proportions are rising, the appearance and quality requirements are getting higher and higher, and the market The prospects are very bright.
