There are many reasons for food waste, which are related to lifestyle and are closely related to packaging factors. Improving packaging is an important aspect of reducing food spoilage and waste. In the food supply chain, avoiding food spoilage and waste, this process can be achieved by optimizing the packaging process. Aluminum foil has excellent barrier properties, thermal and electrical conductivity, reflectivity, etc. These physical properties provide more and better protection for the product, reduce the energy required for cooling, and extend the shelf life of the product. Protecting food does not degenerate, meaning less food waste, and producing these foods requires more resources than the packaging itself, and ultimately achieves greater resource efficiency.
Aluminum foil packaging makes it easier to pack the right amount of food. Therefore, food can be prepared and consumed as needed, thereby reducing waste. At the same time, it also ensures the nutritional content and health needs of the product. Compared to large packaging, small packages prevent product damage and waste, thus saving resources overall. After all, people have realized that food losses and waste are equivalent to wasting resources, including water, land, energy, labor and capital resources. Unnecessarily generating greenhouse gas emissions can lead to global warming and climate change. According to the World Food and Agriculture Organization, food dumped into garbage dumps every year accounts for one-third of global food production. Imagine if the amount of global food loss and waste is concentrated in one country. Its land area is larger than China's. The vast grain fields and grasslands will produce food crops that will not be consumed but will be wasted. It will also be equivalent to the world's largest irrigation water user and the third largest greenhouse gas producer.
