Aluminum foil for packaging has good oxidation resistance. A dense oxide film will be formed on the surface of the aluminum foil, which can effectively prevent contact with oxygen and has good corrosion resistance, thus ensuring the integrity of the medicine. Therefore, aluminum foil is currently a commonly used medical packaging material.
One of the main raw materials for the production of PTP aluminum foil is industrial hard pure aluminum foil, which is commonly called "raw aluminum foil" in the pharmaceutical packaging materials industry. Aluminum foil protects against moisture, light, oxygen and bacteria, which is a key requirement in industries such as food and beverage and pharmaceuticals. What Haomei Alumium offer is aluminum foil jumbo roll for further processing like printing.
In the United States, most pharmaceutical 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. And today, the vast majority of aluminum foil is coated with a "universal" heat seal paint to ensure a good seal.
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 alloy type, rolling process, pinholes, condition, thickness, plate shape, surface quality, mechanical properties. All these will directly affect the performance and protective effect of medicinal aluminum foil.
There are currently three main types of aluminum foil used for pharmaceutical packaging, namely 8079 aluminum foil, 8021 aluminum foil, and 8011 aluminum foil. The three mainly have slight differences in metal element content and thickness.
8011 aluminum foil, also known as PTP aluminum foil, has a thickness of 0.016-0.04mm, a high silicon content, and contains manganese and iron. It has high strength and corrosion resistance. It is often used in pharmaceutical packaging for packaging on the back of medicine capsules or medicine boards.
The production environment requirements of medicinal aluminum foil processing plants are relatively high, such as requiring no less than a 100,000-level purification workshop. As a wholesale ptp blister foil supplier, Haomei Aluminum meet this requirement. Welcome to leave message below to inquire what you need.
