What is an aluminum foil container
Aluminum foil containers made of aluminum foil can be processed into various shapes and are widely used in packaging of pastry baking, airline catering, takeaway, cooked food, instant noodles, instant lunch boxes and other food fields.
Food-grade aluminum foil containers have a crisp appearance and good thermal conductivity, which can reduce waste and protect the environment.
Aluminum foil containers are mostly made of 3003 alloy. As a high-end product, it is often used as a disposable lunch box on airplanes. In daily life, plastic lunch boxes are often used, so aluminum foil containers are also called "airline lunch boxes".
Later, in order to reduce costs, 8011 alloy also began to be used in aluminum foil containers. The reduction in cost has further promoted and used aluminum foil as a lunch box material, but at the same time, the strength of the lunch box is significantly lower than that of 3003 alloy. High-end lunch boxes, especially export aluminum foil containers, still use 3003 alloy.
