How to classify, how to dispose of, which kind of garbage is easy to handle, which kind of garbage is easy to recycle, etc. These issues have also become hotspots and focal points of discussion. Undoubtedly, the purpose of classification is to separate waste for disposal, utilize existing manufacturing capacity, recycle and reuse recycled products, including material utilization and energy utilization, and landfill disposal of useless waste that is temporarily unusable. *Finally achieve the purpose of reducing treatment costs and reducing land resource consumption, only with social, economic and ecological benefits.

However, today with the prevalence of Internet ordering, in the face of the large amount of domestic waste we generate every day, it is not difficult to find that plastic fast food boxes occupy a large proportion. According to incomplete statistics, more than 60 million plastic lunch boxes are used in my country every day, which means that more than 20 billion plastic lunch boxes are produced every year. There are also 1 billion instant noodle bowls, and waste plastics account for about 7% of domestic waste. From left to right, we can see that we have fallen into the "garbage siege" of takeaway packaging. Most of the plastic products used in takeaway are polypropylene and polyethylene, which are difficult to degrade. Currently, Meituan Takeaway, China Cooking Association, China Environmental Protection Foundation and many catering takeaway brands jointly initiated the "Green Takeaway Industry Convention (Green Ten Articles)", which includes the content of "promoting the use of green tableware" and calls on the scientific research community to do The industry provides intellectual support and develops high-quality and low-cost biodegradable environmentally friendly lunch boxes.

Compared with plastic lunch boxes, the safety and environmental protection of aluminum foil lunch boxes, especially the advantages of easy recycling, can show their skills and shoulder this important task.

Aluminum foil lunch boxes have many characteristics and advantages when used as lunch boxes and catering containers. Including: safety and health, high and low temperature resistance, environmental protection, renewable energy saving, good sealing, high-end beauty, convenient and fast, etc. At present, the use of aluminum foil containers and household food packaging aluminum foil has been very common abroad. However, due to consumption habits, consumption concepts, awareness and other reasons, there are large differences in consumption fields and consumption levels in various countries and regions, and the potential for development and application is still large.

In my country, in addition to aluminum foil lunch boxes for aviation, in recent years, aluminum foil lunch boxes and containers have also begun to be used in residents' daily lives. The market development and application examples of related companies also show that the aluminum foil snack box is suitable for China's national conditions, and it can completely enter the catering takeaway, distribution, and pre-packaged food industry, and it can also enter the family to replace plastic and paper lunch boxes. It can be said that the expanded application of aluminum foil lunch boxes and containers is an important choice for promoting green consumption, protecting food safety, saving food, and practicing the concept of green sustainable development.
