When it comes to aluminum lunch boxes, how much do you know about its history? For the younger generation born after the millennium, perhaps the aluminum lunch box has become a strange thing; Even some post-90s generations have never experienced the charm of this kind of lunch box. The aluminum lunch box, with its silver-gray appearance, simple shape and rectangular design, is an indispensable practical utensil on the dining table. In the 80s of the last century, aluminum lunch boxes were popular, and their manufacturing costs were low, the overall weight was light, and they were often used at family dinner tables. This kind of lunch box not only has a certain heat preservation function, but also makes it convenient for people to fill food in advance when they go out to farm. In addition, the aluminum lunch box is extremely durable, the surface is scratch-resistant, the interior is not easy to rust, and has good corrosion resistance.
In that era of scarcity, it was convenient to have a durable appliance as durable as an aluminum lunch box. In addition, aluminum lunch boxes are moderate in size and portable, and have become one of the most common tableware for farmers and students. In many old-era TV dramas, rural students are often seen carrying a silver lunch box to eat, and that is what we call an aluminum lunch box.
The reason why aluminum lunch boxes occupy such a large market share in that era of information closure is mainly because it is moderate and close to the actual needs of consumers at that time. Before the founding of the People's Republic of China, most people in China lived in very difficult conditions, and they paid more attention to practicality and quality for the utensils on the dinner table. In that era, it was not easy to eat enough, and a rice bowl could represent the whole of a family, so it was particularly precious. The durability of aluminum lunch boxes, although they will be slightly deformed with long-term use, does not affect normal use as a whole.
Some people may ask, if the aluminum lunch box is so good, why is it rarely used today? Shouldn't such precious items be passed on? Especially in the case that some tableware on the market is getting higher and higher, more and more fancy, it is even more questionable. In fact, there is also a reason why aluminum lunch boxes are gradually disappearing from the market. Although the quality of aluminum lunch boxes has been praised, there are also problems of instability. First of all, some cheap aluminum lunch boxes do not seal well, and the fit between the box and the lid is not perfect, and if the box body is deformed, the lid will not be closed tightly, which will affect the freshness and taste of the food.
On the other hand, due to the limitations of the production process at that time, the surface of some aluminum lunch boxes was easy to scratch, reducing the service life, and even some cheap aluminum lunch boxes may contain harmful substances, causing potential harm to human health.
From an environmental point of view, the production process of aluminum lunch boxes requires a lot of energy and water resources, which will produce a large amount of waste gas and wastewater, which will bring certain pollution to the environment.
At the same time, discarded aluminum lunch boxes will also increase the burden of garbage disposal. At the time, there was a lack of professional handling of these issues, and not enough attention was paid to them. However, with the increasing awareness of environmental protection, these issues are gradually becoming the focus of attention. In addition, although aluminum lunch boxes have good corrosion resistance, under certain conditions, some components in food will react chemically with aluminum, which may lead to the dissolution of aluminum and ingestion by the human body, posing a threat to health.
Although the intake of aluminum is usually low, food safety has always been a concern, and aluminum lunch boxes have gradually been withdrawn from the market for people's health reasons.
In addition to the above reasons, the disappearance of aluminum lunch boxes is also affected by market competition pressure, the emergence of new catering packaging materials, and changes in consumer demand. With the rapid development of the fast food industry, people have higher requirements for more convenient and fashionable packaging containers, which has promoted the development of new packaging materials such as plastic lunch boxes.
It is worth noting that although there are some problems with aluminum lunch boxes, long-term scientific studies have shown that aluminum lunch boxes under normal use do not cause serious effects on human health. Therefore, a reasonable choice of high-quality aluminum lunch boxes can effectively reduce the potential risks. Although aluminum lunch boxes are no longer popular these days, we can learn from them and pay attention to product quality, environmental protection and food safety to provide consumers with better tableware choices.
