You may not know that the original packaging materials for medicines are plastic and paper, but these packaging is not easy to store, and easy to destroy the ingredients of the medicine, greatly reducing the efficacy of the medicine. After continuous research and improvement, aluminum foil is finally used for the pharmaceutical packaging.
In our daily life, the application of PTP aluminum foil is 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, each country has very strict requirements on the appearance and performance of ptp foil.
The common pharmaceutical aluminum foils have two kinds: 8011 and 8021 aluminum foil. The 8011 aluminum foil thickness is below 0.05mm and 8021 aluminum foil thickness is above 0.05 mm. Generally speaking, the main aluminum foil production process is billet inspection-billet rolling-open middle sub-rolling-coil rolling-finished product-slitting-furnace annealing-finished product packaging.
The surface of medicinal aluminum foil requires no oil stains, no shiny, no black lines, no pinholes, no maculas, no ruffles, etc. More importantly, it should be non-toxic, tasteless, safe and hygienic. It needs to be of strong mechanical properties, high blast resistance, strong puncture and tear resistance.
To reach these requirements, Haomei Aluminum,an experienced aluminum foil producer, optimizes aluminum ingot and adopt advanced production equipment, and strictly control the product shape. In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the medicated foil to ensure clean degreasing.
