Aluminum foil has many characteristics and advantages, including: safety and health, high and low temperature resistance, green environmental protection, renewable energy saving, good sealing, high-grade beauty, convenient and fast.
However, due to consumption habits, consumption concepts, awareness and other reasons, the consumption fields and levels of various countries and regions have great differences, and there is still great potential for the development of applications. It is urgent to speak with one voice globally, spread successful experience and cases, and advocate and promote its application.
In China, in addition to aviation aluminum foil airline container, in recent years has also begun to promote the use of aluminum foil food trays and containers in the daily life of residents.
The market development and application examples of related enterprises also show that aluminum foil fast food container is suitable for China's national conditions, and can enter the food industry of food takeaway, distribution and pre-packaging, as well as family use, and can replace plastic and paper food boxes in large quantities.It can be said that the expanded use of aluminum foil food trays and containers is an important choice to promote green consumption, protect food safety, save food and practice the concept of sustainable development.
Aluminum foil is made of the original aluminum alloy after the rolling process, itself without heavy metal and other harmful substances.In the production process of aluminum foil, high temperature annealing disinfection process is adopted, so that aluminum foil can be in safe contact with food, will not hold or help the growth of bacteria.In most cases, aluminum foil will not react with food.
However, a considerable number of plastic food boxes on the market are produced with unknown raw materials or even fake materials and waste plastics, so the quality and reliability cannot be guaranteed.If the disposable plastic tableware is added with calcium carbonate, talcum powder, industrial paraffin and recycled waste materials, the evaporation residue (n-hexane) of the product will exceed the standard.
Aluminum foil has a high conductivity, can minimize the time and energy related to food processing, refrigeration and secondary heating.Aluminum foil has a good thermal stability. In the process of processing and packaging, aluminum foil containers can well withstand the temperature change. Under the high and low temperature of -20°C -- 250°C, the molecular structure remains stable.It can be baked and barbecued at temperatures ranging from quick-freeze to extreme, during which the foil does not deform, break, melt or scorch, or produce harmful substances.Use aluminum foil to separate the hot coals from the smoke, which can prevent food from burning and causing carcinogens.Aluminum foil food trays and containers are ideal for high temperature sterilization and heat sealing.Aluminum foil food containers can be heated in a variety of ways, including a variety of ovens, ovens, anaerobic heating cabinets, steamers, steam boxes, microwave ovens (be sure to use light waves and grill stalls), pressure cookers, and aluminum foil wrapped food.Related enterprises have developed auxiliary aluminum foil food trays secondary heating equipment and packaging equipment, which can greatly improve the distribution efficiency of catering enterprises and ensure the quality of meals.In contrast, plastic meal boxes and containers are significantly less resistant to high temperatures than aluminum foil, which releases harmful substances that affect human health when exposed to hot food, water or heat.The foamed food box is made of polystyrene.The softening point of polystyrene raw material is between 87℃ and 97℃.Therefore, it should not be used in the environment above 80℃.
Aluminum foil molding is good, in the process of stamping tableware, even in the fold and roll edge parts, will not produce cracks and fracture.Aluminum foils of different shapes, thicknesses, alloys and heat treatment states can be selected according to requirements to accurately reflect the use of the product.Aluminum foil food boxes and containers can be covered with the same material as aluminum foil, paper or other materials. With its characteristics of easy deformation and wrinkle, it can achieve good sealing, strong heat preservation and freshness preservation ability, which can avoid scattering or contamination in the process of food storage and transportation, and significantly reduce food waste.For large food delivery enterprises and central kitchen distribution, automatic capping equipment developed by aluminum foil food box manufacturers can be used to improve the distribution efficiency, which is obviously better than other materials of food boxes.
4. Strong barrier, sealed can protect food flavor, and extend the food shelf life
Although the aluminum foil is very thin, but the barrier is strong, can completely block light, gas and other substances, improve freshness and protect moisture, and prevent the leakage of taste or mixed, can effectively maintain the original flavor and characteristics of the product.The use of aluminum foil food boxes and containers packaged food and pre-packaged food, can achieve hot and cold chain distribution, convenient for production and sales, but also convenient for catering enterprises, restaurants, supermarkets and family storage, to avoid product deterioration, extend the shelf life, reduce food waste.Thus a large amount of energy and energy related to the production process are indirectly saved.
Aluminum has a very high recovery and regeneration, can be recycled for unlimited times, the quality loss is limited, and can maintain its original characteristics.Recycled aluminum can be used to produce many finished products.The renewable process of aluminum foil requires less than 5% of the energy required for the production of primary aluminum, and the emission of greenhouse gas is 95% less than that of primary aluminum.Aluminum foil food trays can be easily compressed after use, easy to sort, thus reducing the amount of waste.
Some post-use aluminum foil food trays and containers may be used for garbage generation.Even when buried, the foil does not contaminate the soil or water.At present, the recycling value of plastic food boxes, especially foam plastic food boxes, is low, the recycling rate is not high, the recycling situation is not ideal, a large number of discarded serious "white pollution", affect the city and natural landscape, but also because it is difficult to degrade and form a "potential harm" to the ecological environment.So in recent years, cities like New York, San Francisco, Seattle, Washington, d.c., Portland, Toronto, Canada, and Paris have banned foaming tableware and water bowls.
Compared with other resources, aluminum resources are abundant, waste aluminum recycling is increasing, and the resource bottleneck is small.Aluminum foil is very thin and light, with a thickness of 0.009-0.03mm and a weight of only a few grams to 10 grams. It USES very few materials, making it the packaging material with the highest product-packaging ratio.If it can be widely applied and popularized, aluminum foil food trays and containers can replace plastic and paper products, save petroleum resources, wood and other resource consumption, improve resource efficiency and improve environmental quality.
There are many ways to recycle aluminum packaging materials, almost any waste aluminum packaging will eventually be recycled.Society, government and the public are increasingly in agreement on recycling, recycling technology is improving, and recycling systems are improving.
Aluminum foil has a bright metallic luster and is compatible with all printing technologies, so designers can give full play to their imagination and design unique patterns and brand logos.Aluminum foil products manufacturers can according to the requirements of food processing enterprises and catering enterprises in the aluminum foil boxes and containers on color printing, embossing, surface coating, embossing, printing, such as processing, to highlight the product difference and beautiful sex, enhance brand image and corporate image, but also to consumers and marketing firms in terms of product traceability.Consumers can also have a good consumption experience in the process of consumption.
With the technical progress and production efficiency improvement of the aluminum industry, the production and manufacturing cost of aluminum and aluminum foil is gradually reduced. The cost of aluminum food tray is close to that of qualified polypropylene (PP) plastic meal box, and the cost performance ratio is increasingly obvious.At the same time, with the progress of society, the concept of green consumption and consumption habits of consumers are gradually established, food safety awareness, health awareness, environmental and ecological awareness, consumption ability continues to improve, large-scale application of aluminum foil food trays and containers to promote the time has come.NongJingXi recently by the China agricultural university students "initiative" the aluminum foil manufacturers to complete under the support of the "consumer aluminum foil boxes containing" recognition and acceptance survey also showed that the large and medium-sized city consumer awareness to this kind of product and catering enterprises is gradually improve, if it is convenient for promotion, sales, strong distribution network, the recycling system is perfect, the application of aluminum foil boxes and containers will be meeting a bigger stage.
China is the world's largest producer of aluminum and aluminum foil, according to shang qingshi, an aluminum industry consultancy.Aluminum foil production reached 3.6 million tons in 2016, accounting for 65% of global production, aluminum foil consumption reached 2.4 million tons, exports of 1.08 million tons, after the massive investment in recent years, China's aluminium foil production has reached the world first-class processing technology and equipment, product quality has reached the international advanced level, the emergence of a batch of domestic leading the world famous production of aluminum foil and aluminum foil products processing enterprises.Thin specification aluminum foil, aluminum foil food boxes and containers, household foil products have been sold in the world.The product development capacity, delivery capacity and service capacity of aluminum foil and aluminum foil products enterprises have been significantly improved. Most of the aluminum foil containers used abroad are made in China, and aluminum foil containers can be said to be fragrant inside and outside.However, we are also confident that we can provide strong support for the next large-scale development of the domestic aluminum foil catering and container application market.
