In China, in addition to aviation aluminum foil lunch boxes, aluminum foil lunch boxes have also been promoted in residents' daily life in recent years. The market development and application examples of related companies also show that aluminum foil lunch boxes are suitable for China's national conditions, and can completely enter the food delivery, distribution, and packaged food industries, and can also be used in homes, and can replace plastic and paper lunch boxes in large quantities. It can be said that the expanded application of aluminum foil lunch boxes is an important choice to promote green consumption, protect food safety, save food, and practice the concept of sustainable development.

Advantages of aluminum foil lunch box

ü Raw materials are non-toxic, quality and safety

In the production process of aluminum foil, continuous casting and rolling, high temperature annealing and disinfection processes are adopted. Therefore, aluminum foil can be safely in contact with food and will not contain or promote the growth of bacteria. 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, so the quality and reliability are difficult to guarantee.

ü High temperature open flame heating, no harmful substances

The molecular structure of the aluminum foil lunch box is stable and does not change under the high and low temperature of -20°C-250°C. It can be used in temperatures ranging from quick freezing to extreme baking and grilling without warping, cracking, melting or scorching, or producing harmful substances. Use aluminum foil to separate high-temperature charcoal fire and smoke, which can avoid carcinogens caused by scorched food. Aluminum foil lunch boxes can be used in various ovens, ovens, anaerobic 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. When they come into contact with high temperature food, water or are heated at high temperature, they will release harmful substances and affect human health.

ü Good heat preservation effect, sustainable heat preservation for 1 hour

Aluminum foil has excellent thermal insulation and freshness preservation, and the tin paper box is matched with the outer paper box, which can last for 1 hour. Although the 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 shelf life and reduce food waste.

ü Can be recycled efficiently, protect the environment and save resources

Aluminum has an extremely high recovery rate and recyclability. 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, thereby reducing the amount of waste produced.

ü Good decoration, improve the quality of takeaway

Aluminum foil has a bright metallic luster and is compatible with all printing technologies, so it allows designers to give full play to their imagination and design unique patterns and brand logos. Manufacturers of aluminum foil products can print in color on the lids of aluminum foil lunch boxes according to the needs of food processing companies and catering companies to highlight product differences and aesthetics, enhance brand image and corporate image, and also benefit consumers and distribution companies. Product traceability. Consumers can also have a good consumption experience in the process of consumption.

Today, with the rapid development of cities, people's urban life is increasingly threatened by resource shortages and environmental pollution. As an energy-saving, environmentally friendly, and renewable metal, aluminum has higher requirements on the surface and mechanical properties of aluminum foil due to the improvement of the automation of the forming of lunch boxes and food containers. The thickness of aluminum foil tends to be thinner and the strength of aluminum foil tends to increase . With the vigorous development and application of aluminum foil products, the demand for aluminum production and machining equipment is also increasing. Hengzhong Heavy Industry provides customers with rolling mill equipment integration technology solutions that can ensure that products can reach a high level of thickness, shape/flatness, Temperature and surface quality indicators. It has been unanimously approved by customers.
