Aluminum foil, as a packaging material with excellent performance, has been widely used in Europe, North America and Japan. However, in China, the largest producer of aluminum foil and the largest exporter of aluminum foil products including aluminum foil containers, the application of aluminum foil in the field of packaging containers is still at a low level. Aluminum foil is different from aluminum sheet.
Prominent performance advantages of aluminum foil lunch box
The excellent physical properties of aluminum, such as high conductivity, good formability and strong barrier property, make aluminum foil have many characteristics and advantages when used as lunch boxes and catering containers, including safety and health, high and low temperature resistance, green environmental protection, renewable energy conservation, good sealing, high-grade beauty, convenience and speed. In addition, the most important feature of “aluminum foil lunch box” is its “green and environmental protection”, which has a very positive significance in saving resources and reducing environmental pollution.
Relevant data show that at present, Shanghai consumes about 5 million disposable containers every day. Calculated by 10g per container, 50 tons of plastic garbage are generated every day, and nearly 15000 tons of plastic garbage will be generated every year. Whether these garbage is buried or incinerated, it will cause serious water or air pollution. Garbage siege has become the most urgent problem faced by large cities and mega cities in China. Many aluminum alloy manufacturers have the ability to produce aluminum plate, but not aluminum foil
Aluminum resources are abundant in reserves, with extremely high recovery rate and regeneration. It can be recycled infinitely, with limited quality loss. It can maintain its original characteristics. Recycled aluminum can be used to produce many manufactured products, and the resource bottleneck is small. In addition, the energy required for the regeneration process of aluminum foil is only less than 5% of the energy required for the production of primary aluminum, and the emission of greenhouse gases is 95% less than that of primary aluminum. Aluminum foil lunch boxes can be easily compressed and sorted after use, thus reducing the amount of garbage generated. Even if the aluminum foil is buried, it will not pollute the soil and water. Compared with the plastic lunch boxes with low recovery rate, which are difficult to degrade, and the paper lunch boxes that are short of resources and easy to be affected by moisture, the use of aluminum foil lunch boxes can bring huge economic and environmental benefits.
