The aluminum foil lunch boxes mentioned are a type of environmentally friendly lunch boxes. Aluminum foil lunch boxes are already very common in certain specific fields and scenarios. Disposable lunch boxes on airplanes and tableware used to heat meals in microwave ovens or ovens are actually aluminum foil.
As early as the 2001 Shanghai APEC meeting, the heads of state used aluminum foil lunch boxes for their outings; during the 2008 Beijing Olympics, aluminum foil lunch boxes were also used for delivering meals to athletes and service personnel; during the 2010 Shanghai World Expo, the daily supply in the Expo employee central kitchen alone was about 6,000 copies, nearly 10,000 copies.
Although the above explains the use of aluminum foil lunch boxes in major occasions,
but its specific advantages have not been listed,
so let's continue to look at it↓
1. Heat preservation and fragrance preservation
Functionality is the primary mission of packaging, and maintaining the taste and flavor of food is the core, so the premise of packing meals is that the rice fragrance remains. However, the delivery of takeaway meals takes at least 30 minutes and at most more than an hour, and the aroma of the food is very easy to lose. This is also the reason why the takeaway experience has never been comparable to that of dine-in. Therefore, heat preservation has become the key to preserving the aroma. Aluminum foil lunch boxes are resistant to high temperatures (up to 121 degrees), have good oil resistance, and have outstanding aroma preservation performance, which can solve these problems well.
The characteristics of preserving aroma and freshness make aluminum foil lunch boxes have food packaging properties. The characteristics of high temperature resistance and good oil resistance make it easy to handle various hot food categories, even in the face of the long-standing problem of takeaway packaging - Chinese food with more oil and soup. It can be said that aluminum foil lunch boxes have natural takeaway properties.
*Aluminum foil lunch boxes are also commonly used for paper-wrapped beverage packaging. The thickness of the aluminum foil in the packaging bag is only 6.5 microns. This thin aluminum layer can be waterproof, maintain freshness, prevent bacteria and prevent pollution.
Does the use of aluminum foil lunch boxes for takeaway packaging aggravate the environmental dilemma?
2. Harmless to the human body
The main material of the aluminum foil lunch box is aluminum foil. There is a dense oxide layer on the surface of the aluminum foil. The chemical properties of this oxide layer are relatively stable. Aluminum ions will not be precipitated unless it is in a strong acid environment.
Moreover, aluminum foil has been used for food packaging in Europe and the United States for no less than 40 years. It has now been widely used in the Middle East. Aluminum foil is suitable for packaging greasy and hot food and reheating food. Aluminum foil is used for food packaging and takeaway packaging, which is harmless to the human body.
3. Environmental protection
The component of the aluminum foil lunch box is aluminum. The recycling rate of aluminum is high. Aluminum can be recycled up to 25 times, which meets the national food hygiene standards, is easy to recycle, and no harmful substances are produced during the treatment process.
Compared with the geological changes caused by "white pollution", aluminum lunch boxes can be weathered in two to three years in the soil, and will not cause continuous damage to the land and implanted changes in properties.
From this point of view, replacing "white box-plastic lunch box" with "silver box-aluminum foil lunch box" is the preferred option for environmental protection.
4. Strong ductility, larger packaging surface area
Aluminum has a physical property, namely ductility. Compared with other metals, the same quality of aluminum can be processed into a larger surface area and package more things.
5. Reasonable price
Although many catering categories have already used aluminum foil lunch boxes, and even businesses specializing in cooking have also put them into use, there are still quite a few catering companies that are in a wait-and-see stage for aluminum foil lunch boxes, and a large part of the reason is cost issues.
