In China, in addition to aviation aluminum foil lunch boxes, aluminum foil lunch boxes have also been promoted in residents' daily lives in recent years. Market development and application examples of related companies also show that aluminum foil lunch boxes are suitable for China's national conditions and can be fully used in catering takeout, delivery, and packaged food industries. They can also be used in households and can replace a large number of plastic and paper lunch boxes. It can be said that the expanded application of aluminum foil lunch boxes is an important choice for promoting green consumption methods, protecting food safety, saving food, and practicing the concept of sustainable development.
Advantages of aluminum foil lunch boxes
1.Raw materials are non-toxic and quality is safe
In the production process of aluminum foil, a high-temperature annealing and disinfection process is used. Therefore, aluminum foil can be safely in contact with food and will not accommodate or help bacterial growth. In most cases, aluminum foil will not react with food. However, a considerable number of plastic lunch boxes on the market are produced with raw materials of unknown origin or even fake materials and waste plastics, and the quality reliability is difficult to guarantee. If calcium carbonate, talcum powder, industrial paraffin, and recycled waste are added to the production raw materials of disposable plastic tableware, it is easy to cause the evaporation residue (n-hexane) of the product to exceed the standard. In order to protect the environment and prevent the harm of plasticizers to society and the human body, some local governments have also formulated regulations to limit the use of disposable non-degradable plastic tableware.
2.High-temperature open flame heating, no harmful substances
The molecular structure of aluminum foil lunch boxes is stable and unchanged under high and low temperatures of -20°C-250°C. Its use temperature can range from rapid freezing to extreme baking and grilling. During this period, the aluminum foil will not deform, crack, melt or burn, and will not produce harmful substances. Using aluminum foil to separate high-temperature charcoal fire and smoke can prevent food from being burned and causing carcinogens. Aluminum foil lunch boxes can be used in various ovens, ovens, oxygen-free heating cabinets, steamers, steamers, and microwave ovens (must be used in light waves and grills). In contrast, the high-temperature resistance of plastic lunch boxes and containers is significantly lower than that of aluminum foil products. They will release harmful substances when they come into contact with high-temperature food, water or are heated at high temperatures, affecting human health.
3.Good insulation effect, can keep warm for 1 hour
Aluminum foil has excellent insulation and freshness preservation. The tin foil box with the outer paper box can keep you warm for 1 hour. Although aluminum foil is very thin, it has strong barrier properties and can completely block light, gas and other substances, improve freshness and protect moisture, and prevent the leakage or mixing of flavors, which can effectively maintain the original flavor and characteristics of the product. Extend the shelf life and reduce food waste.
4.Efficient recycling, environmental protection and resource conservation
Aluminum has a very high recycling rate and recyclability. The energy required for the recycling process of aluminum foil is only less than 5% of the energy required for the production of original aluminum, and the greenhouse gas emissions are 95% less than that of original aluminum. Aluminum foil lunch boxes can be easily compressed and sorted after use, thereby reducing the amount of garbage generated. Compared with other resources, aluminum resources are abundant, and the amount of waste aluminum recycled is constantly increasing. There are many ways and means to recycle aluminum packaging materials, and almost any discarded aluminum-containing packaging will eventually be recycled. Society, government and the public are increasingly reaching a consensus on recycling, and recycling technology is also constantly improving.
5.Good decorative properties improve the quality of takeout
Aluminum foil has a bright metallic luster and is compatible with all printing technologies. Therefore, it allows designers to give full play to their imagination and design unique patterns and brand logos. Aluminum foil product manufacturers can print in color on the lid of aluminum foil lunch boxes according to the needs of food processing companies and catering companies to highlight the difference and beauty of the products, enhance the brand image and corporate image, and also facilitate consumers and distributors to trace the source of products. Consumers can also have a good consumption experience during the consumption process.
