The main property of aluminum foil is that it acts as a reliable barrier. Even thin aluminum foil, which is only 6 microns thick (thinner than a human hair), protects against light, oxygen, moisture, bacteria and harmful odors. Therefore, food and pharmaceuticals in aluminum packaging greatly increase their shelf life.
PTP aluminum foil is a material commonly used to make pharmaceutical packaging. It has the advantages of moisturizing and blocking gas and light. It is mainly composed of aluminum foil and glue layer, which can effectively protect the quality and safety of medicines.
When used as pharmaceutical packaging materials, aluminum foil is the only metal material in the packaging materials. In the field of modern packaging, , almost all composite flexible packaging materials that require opacity or high barrier properties use aluminum foil as the barrier layer. When made into a blister package, it can be crushed with a little pressure, making it convenient for patients to take medicine and carry it around. Haomei Aluminum provides the wholesale ptp blister foil for global customers.
Medicinal PTP aluminum foil is generally "hard" aluminum. In the United States, most pharmaceutical aluminum foils are around 25 microns thick, 25.4 µm to be precise. In Europe, the thickness of 20.0 µm is more common, and has a greater length advantage for the same weight of raw materials. In recent years, countries have been moving towards thinner 20.0 µm aluminum foil, regardless of market.
Medicinal aluminum foil has a protective effect on drugs, so it has higher requirements on the control of details in all aspects of production, such as the selected alloys, rolling process, pinholes, condition, thickness, plate shape, surface quality, mechanical properties,etc. All will directly affect the performance and protective effect of medicinal aluminum foil.
In addition to meeting basic requirements such as thickness, surface flatness, tensile strength, elongation at break, etc., aluminum foil for medicine packaging also needs to comply with pharmaceutical hygiene standards to ensure that it does not contaminate pharmaceuticals.
PTP aluminum foil testing mainly involves physical performance testing, chemical performance testing, packaging performance testing and microbial testing. In the process of drug production and circulation, PTP aluminum foil testing plays a key role and helps improve drug quality and safety.
