Description
Pharmaceutical Aluminum Foil is a thin film material made of aluminum metal, usually processed by cold rolling or hot rolling. Its substrate is pure aluminum or aluminum alloy, which has been rolled and annealed many times to make the film have uniform thickness and high strength. The surface of Pharmaceutical Aluminum Foil is smooth and flat, without obvious defects or impurities. During the processing, the surface of aluminum foil can undergo different treatment processes, such as coating or electroplating.
Features
Excellent barrier properties
The barrier property of Pharmaceutical Aluminum Foil is one of its most outstanding advantages. The high density and compactness of aluminum metal can effectively isolate oxygen, water vapor, light and other harmful substances in the air, ensuring that the drugs in the package are not affected by the external environment during long-term storage. The oxygen permeability of aluminum foil is usually less than 0.01 cm³/(m²·day·atm), and the water vapor permeability is as low as 0.1 g/(m²·day). These excellent barrier properties can greatly extend the shelf life and stability of drugs.
High strength and tensile resistance
During the manufacturing process, Pharmaceutical Aluminum Foil undergoes precise rolling and annealing processes, which makes it have extremely high mechanical strength and good ductility. The tensile strength of aluminum foil can generally reach more than 180 MPa, while the ductility is usually more than 10%. This enables Pharmaceutical Aluminum Foil to withstand the external force stretching that may occur during the packaging process, while maintaining a good appearance and packaging performance, and is not easy to break or deform.
Strong chemical stability
Aluminum metal itself has good chemical stability and can resist the erosion of most chemicals. A dense aluminum oxide film is usually naturally formed on the surface of Pharmaceutical Aluminum Foil. This film layer can effectively prevent the aluminum foil from reacting with moisture, acid and alkali and other substances, and ensure its long-term stability in various storage and transportation environments. This chemical stability of aluminum foil makes it an ideal choice for pharmaceutical packaging materials.
Good heat sealing properties
During the processing process, Pharmaceutical Aluminum Foil is usually optimized to ensure that it has good heat sealing properties. The heat seal strength can reach more than 3N/cm, which means that during the packaging process, the aluminum foil can be firmly bonded with other materials (such as plastic film, cardboard, etc.) to form a sealed package. This feature is crucial for the preservation of medicines, which can prevent the intrusion of external contaminants and protect the safety of medicines.
