Is Aluminum Foil Lunch Box Harmful to Human Body?

Aluminum foil containers is an environmentally friendly lunch box, which has the advantages of heat preservation and fragrance, harmless to human body, environmental protection, and large packaging surface area; therefore, the use of aluminum foil lunch box is not widely used. Many people think that aluminum contains heavy metals and other harmful substances, and the use of aluminum foil lunch boxes will cause poisoning. In fact, aluminum foil lunch boxes are non-toxic, because the melting point of aluminum is 660 degrees Celsius, and ordinary meals will not harm the human body.

Is Aluminum Foil Lunch Box Harmful to Human Body

Advantages of aluminum foil lunch boxes:

1. Insulation and fragrance
Aluminum foil lunch boxes are usually used as paper-packed 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
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, and the recycling of aluminum can reach 25 times. Compared with the geological changes caused by “white pollution”, the aluminum lunch box can be weathered after being placed 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.
