1, heat preservation and fragrance protection
Aluminum foil lunch boxes are usually used as paper-wrapped beverage packaging. The aluminum foil in the packaging bag is only 6.5 microns thick, and this thin aluminum layer can be waterproof, fresh-keeping, antibacterial and antifouling. The characteristics of fragrance preservation make aluminum foil lunch box have the attributes of food packaging, and the characteristics of high temperature resistance and oil resistance make it easy to control all kinds of hot meals and foods, even Chinese food with more oil and soup, which is a long-standing problem in takeaway packaging. It can be said that aluminum foil lunch boxes have natural take-away properties.
2, harmless to human body
Food is the most important thing for people, and food safety is the top priority. The embodiment of food safety not only exists in the food itself, but also includes lunch boxes that come into contact with food.
The popular plastic lunch boxes on the market are very harmful to human health. When the disposable foamed plastic tableware contains hot food or boiled water with the temperature above 65 degrees, the toxic substances contained in the tableware are easily immersed in the food. If the concentration of this harmful substance exceeds the standard, the toxicity will be even greater. The main material of aluminum foil lunch box is aluminum foil, and the surface of aluminum foil has a dense oxide layer. 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 precipitate.
3. Environmental protection
The composition of aluminum foil lunch box is aluminum, and the recovery rate of aluminum is high, up to 25 times, which conforms to the national food hygiene standards, is convenient to recover, and does not produce harmful substances during processing. Compared with the geological changes caused by "white pollution", aluminum lunch boxes can be weathered after being placed in the soil for two to three years, which will not cause continuous damage to the land and change the nature of implantation.
4. Strong ductility and larger package surface area.
Aluminum has a physical property, which is ductility. Compared with the quality of aluminum, other metals can process a larger surface area and package more things.
Disadvantages of disposable aluminum foil lunch box
1, merchants and consumers lack systematic understanding of it.
Both consumers and restaurants lack a correct and systematic understanding of aluminum foil lunch boxes. The biggest cognitive misunderstanding is that aluminum contains harmful substances such as heavy metals, and aluminum foil lunch boxes will be poisoned. There are quite a few people who mistakenly think that aluminum foil is "tin foil" and take it for granted that aluminum foil contains heavy metals and is a scarce resource.
Even if a few catering enterprises will find the wonderful use of aluminum foil lunch boxes, they will give up when they see the "white pervasion" around them, and more enterprises will give up because of insufficient cognition and price sensitivity.
2, the cost is high
From the price point of view, the price of aluminum foil lunch boxes on the market is about 20% higher than that of ordinary plastic lunch boxes.
From the perspective of recycling cost, due to the imperfect garbage sorting system in China and the poor recycling channels of aluminum foil lunch boxes, food enterprises can't know the recycling destination of aluminum products, so they can't get subsidies from recycled aluminum.
The cost of aluminum foil lunch boxes is already relatively high, and the recycling channels are not smooth. The road to cost recovery of food enterprises is blocked, and businesses are even more reluctant to use them.
3. Poor sales channels
Compared with lunch boxes made of other materials, the distribution network of aluminum foil lunch boxes is not perfect. Aluminum foil lunch boxes are hard to find because of their large space occupation, low relative value, small sales volume and high supermarket entrance fee.
Is the aluminum foil lunch box poisonous?
Aluminum foil lunch box is a new type of non-toxic and environmentally friendly tableware.
1, the main component of aluminum foil lunch box is aluminum, so it will react with acid like an aluminum can, and the salt generated by aluminum and organic acid will react with gastric acid to generate aluminum chloride, so pay attention when using it. Generally speaking, it is often used to steam rice, and there is no other fuel, which is harmless to the human body and can be used safely. However, if there is still unqualified tin foil in our life, it may have adverse effects on the human body. For our health, we must choose qualified aluminum foil lunch boxes.
2. After excessive accumulation of aluminum in human body, it will damage brain cells of human body, resulting in memory decline, and this poisoning process is not easy to be detected. However, generally speaking, the melting point of aluminum is 660 degrees Celsius, so the risk of being sucked out in barbecue is relatively small.
3. Aluminum foil can not only transmit energy, but also prevent the meat from directly contacting the flame, which is equivalent to wearing a layer of "fire-proof clothing" and reducing the chance of being burned. In addition, wrapping food with aluminum foil can effectively prevent water loss.
