Produzione di fogli di alluminio per imballaggi farmaceutici
The medicinal aluminum foil material is currently the most used material for pharmaceutical packaging. Most pharmaceutical factories choose to use blister aluminum foil, alluminio freddo, tropical aluminum, and easy-to-tear aluminum to package drugs.
In daily life, the application of medicinal aluminum foil is now very extensive and mature. The main uses of medicinal foil are blister packaging of medicine capsules and tablets, and bag-like packaging of powder granules and liquids. Because of its direct contact with edible drugs, both the country and the pharmaceutical factory have very strict requirements on the appearance and performance of the medicinal foil.
There are two commonly used medicinal foil materials in the market, namely 8011 foglio di alluminio e 8021 foglio di alluminio. The thickness of 8011 alloys is generally below 0.05mm, and the thickness of 8021 alloys is above 0.05mm. The two medicinal foil materials are similar in material, but there are some differences in the production process.
In generale, the main production process flow is: billet inspection-billet rolling-open middle sub-rolling-coil rolling-finished rolled product-slitting-furnace annealing-finished product packaging. After the successful production of medicinal foil, the surface of medicinal aluminum foil must be free of greasy dirt, no shiny crystals, no black lines, no pinholes, no maculas, no lotus leaf edges, eccetera.
In the production process of medicinal foil materials, the control of surface and performance is mainly in the following aspects:
1, control the quality from the source and strictly inspect the aluminum foil blanks;
2, during the rolling process, the surface quality is controlled by cleaning the rolls and controlling the roughness, selezionando l'olio di rotolamento, riducendo la viscosità dell'olio di rotolamento, e controllare la velocità operativa della macchina;
3, Once again, during the slitting process, ensure that the edges of the aluminum coil are neat during slitting, and there should be no quality problems such as lotus leaf edges;
4, Finally, in the annealing process, il tempo di ricottura e la temperatura di ricottura sono controllati in base ai requisiti prestazionali del foglio medicato per garantire uno sgrassaggio pulito.
With the development of the pharmaceutical industry, foglio di alluminio medicinale, with its excellent moisture resistance, proprietà barriera, drug resistance, chemical stability, hygienic properties, and application ratio continue to rise and is deeply loved by pharmaceutical factories and users. Allo stesso tempo, with the increase in demand for medicinal foil products, the appearance and quality requirements of medicinal foil are getting higher and higher, and the market prospect is very broad.
