Aluminum Alloy 8011 H34 Prepainted Aluminum Strip Coil For Pharmaceutical Packaging

Manufacturing Process

• Base Material Preparation: High-quality aluminum ingots are first melted and cast into aluminum coils. These coils are then rolled through a series of rolling mills to achieve the desired thickness and width of the aluminum foil. The surface of the aluminum foil is carefully treated to ensure good adhesion of the paint.
• Coating Application: The prepared aluminum foil is fed into a coating machine. In the machine, the paint or coating material, which can be in the form of liquid paint, powder coating, etc., is evenly sprayed or rolled onto the surface of the aluminum foil. The coating thickness can be precisely controlled according to specific product requirements.
• Drying and Curing: After coating, the aluminum foil enters a drying and curing chamber. Through heating and other processes, the paint or coating is dried and cured to form a firm and durable coating film on the surface of the aluminum foil.

Properties and Advantages

• Excellent Corrosion Resistance: The paint coating on the surface of the prepainted aluminum foil acts as a protective layer, effectively isolating the aluminum substrate from the outside environment and preventing corrosion caused by moisture, oxygen, and other substances. This greatly extends the service life of the aluminum foil.
• Good Decorative Performance: It is available in a wide range of colors and finishes, such as matte, glossy, metallic luster, etc. It can meet different aesthetic needs in various applications and provide rich decorative effects.
• High Weather Resistance: The prepainted aluminum foil has good resistance to sunlight, rain, snow, and other weather conditions. It can maintain its color and performance stability for a long time outdoors without fading, cracking, or peeling easily.
• Easy Processing: The prepainted aluminum foil retains the excellent formability of aluminum foil. It can be easily cut, bent, stamped, and formed into various shapes, meeting the processing requirements of different products.
• Good Chemical Resistance: It has a certain resistance to common chemicals, which makes it suitable for use in some environments where it may come into contact with chemicals.
