Disposable lunch boxes are widely used in daily life, such as takeaway packaging, picnics and other outdoor activities. Although traditional plastic lunch boxes are low-priced and easy to use, they put great pressure on the environment. Small takeaway lunch boxes may take a long time to degrade naturally. With the increasing severity of environmental pollution, aluminum foil lunch boxes have followed the trend of environmental protection and become the most widely used type of lunch boxes. At present, the use of aluminum foil containers and household food packaging aluminum foil has become very common at home and abroad.

The safety of food packaging materials is an important part of food safety. Aluminum foil lunch boxes are a type of green and environmentally friendly lunch box containers. The raw materials are 3 series or 8 series aluminum foil, which are stamped by special equipment. The raw materials are non-toxic and recyclable, and are more and more widely used in daily life. Among them, 3004 aluminum foil is one of the main base materials for lunch boxes.
