The most common aluminum alloys of the aluminum foil jumbo roll is 8011, 8021, 8079, 1235, 3003,etc. They are used in a wide range of applications after processing, such as beer labels, cables, pharmaceutical packaging, household foil food packaging, bottle cap materials, heat sealing foil, battery, etc.
Food packaging aluminum foil is an important market for aluminum foil applications. Due to its thin thickness and low strength, aluminum foil is generally not used as a packaging material alone, but is often used together with plastic, paper and other materials as part of composite packaging.
Aluminum foil acts as a positive current collector in lithium batteries due to its good properties. Battery aluminum foil has higher purity. Currently, the battery aluminum foil produced in the market is mainly made of 1060, 1070, 1100 and 1235 alloy. The above alloys all belong to the 1000 series. This series of alloys contains a large amount of aluminum, and the purity can reach more than 99.00%. 1235 battery aluminum foil contains 99.35% aluminum.
At home, people use aluminum foil to store food, cover baking surfaces and wrap foods such as meat to prevent them from losing moisture while cooking. People may also use aluminum foil to wrap and protect more delicate foods such as vegetables when grilling. Finally, it can be used to line grill pans to keep things tidy and to scrub pots or grill grates to remove stubborn stains and residue.
When used as pharmaceutical packaging materials, aluminum foil is the only metal material in the packaging materials. Aluminum foil is non-toxic and odorless. It also has excellent conductivity, light-shielding properties, extremely high moisture resistance, gas barrier and taste retention, which can most effectively protect the packaged items.
The production process of large rolls of aluminum foil for sale includes the following steps: raw material selection and preparation, usually 1000 series, 3000 series and 8000 series; smelting, casting and rolling, heat treatment, surface treatment, quality inspection and packaging. In short, the aluminum foil production process requires multiple processes and strict quality control to ensure the performance and quality of the final product.
