The public knows very little about aluminum foil lunch boxes, the advantages of aluminum foil lunch boxes, the protection of their own health and their contribution to sustainability, and their usage concepts and habits have not yet been formed.
There are quite a few consumers and catering operators who have misunderstandings. For example, they think that using aluminum foil lunch boxes will cause "aluminum poisoning". Aluminum contains heavy metals and other harmful substances. In fact, the surface of aluminum foil has a dense layer of oxide. The chemical properties of this oxide layer are relatively very stable. As long as aluminum ions are not precipitated in a strong acid environment, there is no problem in containing food and processing it normally.
The so-called aluminum poisoning occurs when substandard food additives are used and has nothing to do with aluminum foil packaging. In fact, in foreign countries, aluminum foil containers and aluminum foil lunch boxes have already entered restaurants, supermarkets, and homes, and are very commonly used. There are also quite a few people who mistakenly think aluminum foil is "tinfoil", taking it for granted that it contains heavy metals and is a scarce resource, which also affects the popular use of aluminum foil.
