8011 Household Aluminum Foil Pack Bag Foil Aluminum Foil Jumbo Roll Food Usage

Characteristic Features

The large rolls of food-grade aluminum foil possess multiple core advantages. They are made of primary aluminum alloy, undergo high-temperature annealing and disinfection, have a dense oxide layer on the surface, contain no harmful substances and are chemically stable, allowing safe contact with food. They can also inhibit bacterial growth. The temperature resistance range is wide (-20°C to 250°C), the molecular structure is stable, suitable for high-temperature sterilization and heat sealing treatment. The barrier property is strong, completely blocking light, gas, etc., effectively maintaining the original flavor of the food, locking in moisture, extending the shelf life, and suitable for cold and hot chain distribution. The aluminum material has a high recycling rate and can be infinitely recycled, with lower energy consumption and greenhouse gas emissions during regeneration compared to primary aluminum. It is environmentally friendly. It has a bright metallic luster, is compatible with various printing and surface treatment processes, which can enhance the product's appearance and brand recognition. At the same time, it is lightweight and easy to carry, has good formability, is not prone to cracking when pressed or folded, and is convenient for sealing use.

Aluminum foil production process
The ingot is heated to 400-500℃ and undergoes multiple passes of hot rolling by a continuous rolling machine, reducing the thickness from several tens of millimeters to approximately 3mm of the intermediate sheet; then the intermediate sheet is sent to a cold rolling machine at room temperature and undergoes multiple passes of cold rolling, reducing the thickness to the target size of 6-12 micrometers; afterwards, the cold-rolled foil is rolled into a coil and sent to a annealing furnace at 350-450℃ to soften and eliminate internal stress; after annealing, the coil is unwound and cut into 1-2 meter widths for common use, and at the same time, the performance and thickness accuracy are inspected using automated equipment; finally, the qualified foil is rewound onto a large core shaft, packaged, labeled, and stored for shipment.
