Although aluminum foil lunch boxes have many advantages, so far, compared with my country's vast catering and food packaging market, aluminum foil lunch boxes and containers are far from being widely promoted and used. There are many reasons for this phenomenon. Among them, price factors, consumer awareness, and convenience of sales and distribution are the three main reasons. First, when some catering companies are in competition, in order to reduce costs, they give priority to low-quality and low-priced low-grade foam lunch boxes and other plastic lunch boxes. In the impression of many companies and consumers, aluminum foil lunch boxes are high-end products that can only be used on airplanes. But in fact, due to the decline in raw material prices and the improvement of production and processing technology, aluminum foil is now close to qualified plastic lunch boxes and degradable meals. However, if the cost expenditure that can be reduced in recycling, water saving, storage and transportation, heating and energy saving is taken into account, the price-performance ratio advantage has already emerged.
Secondly, consumers know very little about the advantages of aluminum catering, its protection to their own health and its contribution to sustainability, and the concept and habit of using it have not yet been formed. Quite a number of consumers and catering operators have cognitive misunderstandings. For example, they worry that the use of aluminum catering containers will lead to "molybdenum poisoning" and that aluminum contains harmful substances such as heavy metals. Little do they know that there is a dense oxide layer on the surface of aluminum foil. The chemical properties of this oxide layer are relatively stable. As long as it is not in a strong acid environment, aluminum ions will not be precipitated. It is absolutely safe for normal food storage and processing. All the poisoning is caused by the use of unqualified food additives, which has nothing to do with aluminum packaging. At present, in foreign countries, aluminum box containers and aluminum catering have long been introduced into restaurants, supermarkets, and homes, and are widely used. Quite a number of people mistakenly believe that aluminum catering is "tinfoil" and take it for granted that it contains heavy metals, which also affects the popularization of aluminum foil.
