Aluminum foil lunch boxes are also called tinfoil lunch boxes, commonly used are 8011 aluminum alloy or 3003 aluminum alloy. 3003 aluminum foil for lunch boxes has excellent moisture-proof properties, light-shielding properties and high barrier capabilities. Lunch boxes made of it are light in weight, have good heat preservation properties, can be heated directly, are clean and hygienic, comply with national food safety and hygiene standards, and will not produce Hazardous substances and high recovery rate.
American Standard 3003 aluminum foil is a product made from 3 series aluminum ingot raw materials. After cold rolling or hot rolling, it has the characteristics of uniform thickness, smooth surface, no pinholes, no dust particles, and no odor. It is widely used in electronic foil, container foil, aluminum honeycomb core, lunch box materials, electrolytic capacitors and other fields.
In terms of electronic foils, 3003 aluminum foil may be used in applications such as manufacturing electronic devices or circuit boards. In the field of container foil, it can be used to manufacture food packaging, lunch boxes and other products. Aluminum honeycomb core is made of multiple layers of aluminum foil bonded together and is used to build lightweight, high-strength structures, such as in the aerospace industry. At the same time, 3003 aluminum foil also has certain uses in applications such as electrolytic capacitors.
