1. Insulation and fragrance
Aluminum foil lunch boxes are usually used as paper-packaged beverage packaging. The thickness of the aluminum foil in the packaging bag is only 6.5 microns. This thin aluminum layer can be waterproof, maintain fresh taste, and prevent bacteria and stains. The characteristics of preserving fragrance and freshness make the aluminum foil lunch box have the properties of food packaging, and the characteristics of high temperature resistance and oil resistance make it easy to control all kinds of hot meals, even in the face of the old difficulty of takeaway packaging - oil and soup More Chinese food is not a problem. It can be said that aluminum foil lunch boxes have natural takeaway properties.
2. Harmless to human body
People take food as the sky, and food safety is the first. The manifestation of food safety not only exists in the food itself, but also includes the lunch boxes that come into contact with the food.
The popular plastic lunch boxes on the market are extremely harmful to human health. When the disposable foam plastic tableware contains hot food or boiling water with a temperature of over 65 degrees, the toxic substances contained in the tableware are easily immersed in the food. The concentration of this harmful substance exceeds the standard, and the poison will be even greater. The main material of aluminum foil lunch box is aluminum foil. 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.
3. Environmental protection
The composition of the aluminum foil lunch box is aluminum. The recycling rate of aluminum is high. The recycling of aluminum can reach 25 times. Compared with the geological changes caused by "white pollution", the aluminum lunch box can be weathered in the soil for two to three years, and will not cause continuous damage to the soil and changes in the implanted properties.
4. Strong ductility and larger packaging surface area
Aluminium has a physical property called ductility, which allows you to machine more surface area and pack more stuff with the same mass of aluminium than other metals.
