What are the advantages of aluminum foil lunch boxes and containers?

1. The raw materials are non-toxic and the quality is safe

Aluminum foil is made of primary aluminum alloy after rolling through multiple processes, and it has no harmful substances such as heavy metals. In the aluminum foil production process, a high-temperature annealing and disinfection process is used. Therefore, the aluminum foil can be safely in contact with food and will not contain or help 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 from unknown sources, even fake materials, and waste plastics, and the quality and reliability of them are difficult to guarantee. If calcium carbonate, talcum powder, industrial paraffin, and recycled waste are added to the production of disposable plastic tableware, it is easy to cause the evaporation residue (n-hexane) of the product to exceed the standard. In July 2013, the General Administration of Quality Supervision, Inspection and Quarantine, the State Administration for Industry and Commerce, and the State Food and Drug Administration issued the "Notice on Effectively Strengthening the Supervision and Management of Disposable Foamed Plastic Tableware". 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 restrict the use of disposable non-degradable plastic tableware.

2. Convenient heating, no harmful substances will be generated after heating

Aluminum foil has high conductivity, which can minimize the time and energy associated with food processing, refrigeration and secondary heating. Aluminum foil has good thermal stability. In the process of processing and packaging, aluminum foil containers can withstand temperature changes well. Under the high and low temperature of -20℃-250℃, the molecular structure is stable and does not change. Its use temperature can range from rapid freezing to extreme baking and grilling. During this period, the aluminum foil will not be deformed, cracked, melted or burnt, and will not produce harmful substances. Use aluminum foil to separate high-temperature charcoal fires and smoke to avoid carcinogens caused by food scorching. Aluminum foil lunch boxes and containers are very suitable for high-temperature sterilization and heat sealing. Aluminum foil lunch box containers can be heated in a variety of ways, including various ovens, ovens, anaerobic heating cabinets, steamers, steamers, microwave ovens (must be used in light waves and grilling), pressure cookers to heat foods wrapped in aluminum foil. Related companies have developed supporting aluminum foil lunch box secondary heating equipment and packaging equipment, which can greatly improve the distribution efficiency of catering companies and ensure the quality of meals. 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 heated at high temperatures, which will affect human health. (The foamed lunch box is made of polystyrene material. The softening point of polystyrene material is between 87°C and 97°C. Therefore, it cannot be used in a temperature environment above 80°C.)

3. Easy to shape, convenient to seal and cover, ensure food hygiene

The aluminum foil has good formability. During the process of stamping the tableware, cracks and breaks will not occur even in the wrinkled and curled parts. You can choose aluminum foils of different shapes, thicknesses, alloys and heat treatment states according to your needs to accurately reflect the purpose of the product. Aluminum foil lunch boxes and containers can use the same aluminum foil material lid, paper or other material lids, using its easy to deform and wrinkle characteristics to achieve a good seal, strong heat preservation and freshness ability, can avoid Spilled or contaminated during food storage and transportation, significantly reducing food waste. For large-scale food delivery companies and central kitchen distribution, automatic capping equipment developed by aluminum foil lunch box manufacturers can be used to improve distribution efficiency, and the effect is significantly better than other material lunch boxes.

4. Strong barrier, can protect the original taste of food after sealing, and extend the shelf life of food

Although aluminum foil is very thin, it has strong barrier properties. It 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. Foods and pre-packaged foods packaged in aluminum foil lunch boxes and containers can realize cold and hot chain distribution, which is convenient for production and sales, and is also convenient for catering companies, restaurants, supermarkets and households to store, avoid product deterioration, extend shelf life, and reduce food waste. As a result, it also indirectly saves a large amount of energy and energy related to the production process of the product.

5. It can be recycled and reused efficiently, protect the environment and save resources

Aluminum has a very high recovery rate and reproducibility, can be recycled indefinitely, has limited quality loss, and can maintain its original characteristics. Recycled aluminum can be used to produce many finished products. 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 greenhouse gas emissions are 95% less than that of primary aluminum. The aluminum foil lunch box can be easily compressed after use, easy to sort, thereby reducing the amount of garbage.

Part of the used aluminum foil lunch boxes and containers may be used to generate waste to generate electricity. Even if the aluminum foil is buried, it will not pollute the soil and water. At present, the recycling value of plastic lunch boxes, especially foamed plastic lunch boxes, is low, the recycling rate is not high, and the recycling situation is very unsatisfactory. A large number of discarding causes serious "white pollution", affecting the city appearance and natural landscape, and it is difficult to degrade. Form "potential harm" to the ecological environment. Therefore, in recent years, New York, San Francisco, Seattle, Washington, DC, Portland, Toronto, Canada, and Paris, France, and other metropolises have banned products such as foam tableware, drinking glasses and bowls.

Compared with other resources, aluminum has abundant resource reserves, and the amount of scrap aluminum recycling continues to increase, and the resource bottleneck is small. Aluminum foil is very thin and light. The thickness is usually 0.009-0.03mm, and the weight is only a few grams to 10 grams. It uses very few materials. It is the packaging material with the highest product-to-packaging ratio. If aluminum foil lunch boxes and containers can be widely used and promoted, they can replace plastic and paper products, save a lot of resource consumption such as oil resources and wood, improve resource efficiency, and improve environmental quality.

There are many ways and ways to recycle aluminum packaging materials, and almost any discarded aluminum-containing packaging will eventually be recycled. Society, government, and the public are increasingly agreeing on recycling, recycling technologies are constantly improving, and recycling systems are constantly improving.

6. Good decorative characteristics, highlighting product differentiation and grade

Aluminum foil has a bright metallic luster and is compatible with all printing technologies. Therefore, designers can give full play to their imagination and design unique patterns and brand logos. Manufacturers of aluminum foil products can perform color printing, surface coating, embossing, embossing, and coding on aluminum foil lunch boxes and containers according to the needs of food processing companies and catering companies to highlight the differences and aesthetics of their products. Enhancing the brand image and corporate image is also conducive to consumers and distribution companies in product traceability. Consumers can also have a good consumption experience in the process of consumption.

7. The cost-effective advantage is gradually emerging, and the time for application promotion has arrived

With the technological advancement of the aluminum industry and the improvement of production efficiency, the production and manufacturing costs of aluminum and aluminum foil have gradually decreased. The cost of aluminum lunch boxes has been close to that of qualified polypropylene (PP) plastic lunch boxes, and the cost-effective advantage has become more and more obvious. At the same time, with the progress of society, consumers have gradually established green consumption concepts and consumption habits, food safety awareness, health and hygiene awareness, environmental and ecological awareness, and consumption capacity have continued to increase. The time has come for the large-scale application of aluminum foil lunch boxes and containers to promote. The "Consumer Aluminum Foil Lunch Box Container Awareness and Acceptance Survey" completed recently with the support of the "Global Aluminum Foil Manufacturers Initiative" also shows that consumers and catering companies in large and medium-sized cities are gradually becoming aware of such products. If the promotion is strong, the sales and distribution network is convenient, and the recycling system is perfect, the application of aluminum foil lunch boxes and containers will reach a higher level.

8. The production and supply capacity of aluminum foil is improved to provide strong support for expanding applications

According to information from the aluminum industry consulting agency Shangqing Times, China has become the world's number one producer of aluminum and aluminum foil. In 2014, the production capacity of aluminum foil reached 3.62 million tons per year, and the output reached 3.2 million tons. The average annual growth rate of aluminum foil output in the past 10 years has reached 20.6%. In 2014, aluminum foil consumption reached 2.364 million tons, an increase of 12.03% year-on-year, and the average annual growth rate of aluminum foil consumption from 2004 to 2014 reached 17.31%. In 2014, the export volume of aluminum foil was 867,700 tons, and the net export volume was 800,000 tons. From 2004 to 2014, the annual export volume increased by 27.74%. In 2014, the net export volume of aluminum foil accounted for 25.25% of the output. After large-scale investment in recent years, China's aluminum foil production and processing technology and equipment have reached the world's first-class, product quality has reached the international advanced level, and a number of domestic leading and world-renowned aluminum foil manufacturers and aluminum foil product processing companies have emerged. Thin-gauge aluminum foil, aluminum foil lunch boxes and containers, household foils and other products have been sold all over the world. In the process of engaging in export trade, aluminum foil and aluminum foil products companies have significantly improved their product development capabilities, delivery capabilities, and service capabilities, which can provide strong support for the next large-scale development of the domestic aluminum foil lunch box and container application market.
