In recent years, with the strong rise of takeout, the meal box also presents a rapid growth trend, providing convenient dining options for the general public. The takeout service develops rapidly, so how did it come into being? Here is the history of the lunch box:

Lunch box first appeared in the middle of the 19th century, when European assets after the performance was stable passive role for most of the workers' groups because of the employment system is not yet complete, so can't go home at noon meal, and then the factory system in the collective supply of food and beverage is not developed, so the workers can only be cooking good food, such as eggs, vegetables, meat, etc., used for serving for cleaning up tobacco, to the work place while resting time repast, this should is the earliest prototype boxes.

By the beginning of the 20th century, thanks to the further improvement of the bourgeois system, it was easy to produce a kind of food that could be monopolized. At this time, the producers were roughing up the tobacco cans, improving the space and making innovative ways. Therefore, the bento lunch box was further developed in the capitalist society.

In the 1960s and 1970s, with the development and improvement of new technology, metal lunch boxes were gradually phased out, and vinyl lunch boxes began to rise, and the appearance of the food box technology has tended to mature.

By the early 2000s, the vinyl box (styrofoam) had become a mainstream disposable box. Because disposable foamed plastic tableware in the production, use, recycling and other links there are serious problems. Blowing agent used in the production process, some will damage the ozone layer of the atmosphere, some have serious safety hazards; Improper use in high temperature, easy to produce harmful substances to human health; It will cause serious environmental pollution if it is discarded after use. It is difficult to degrade the soil and groundwater, and it is very difficult to recover and treat. Therefore, approved by the State Council, in January 1999, the State Economic and Trade Commission issued the "elimination of backward production capacity, process and product catalogue" (the State Economic and trade Commission order No. 6, hereinafter referred to as the order no. 6), which time limit for the elimination of disposable foaming plastic tableware before the end of 2000.

Probably arrived 2003, the one-time tableware that domestic beginning has manufacturer to introduce PP injection mold. Most adopt imported machine mould. In the early stage, it mainly exported to Europe and The United States and other developed markets. With the improvement of domestic production level and the state's attention to food safety. The domestic market has been booming in recent years.

Along with the development of the network, delivery platform has penetrated to the food industry in recent years, the cover of the limitation of PP boxes shown slowly, will appear in the process of transportation is aspersed leakage, no heat preservation, and there will be a steal to eat, room personnel to the lunch box of rice hands this extreme behavior, and in order to save cost and existing market of this kind of PP boxes will use recycled material, and adding calcium carbonate, paraffin wax, harmful material such as slippery powder, often use this kind of matter will affect people's health, greatly reduces the take-away shop and even the entire food industry reputation, to consumers caused by psychological panic. PS: Here are two ways to identify bad food boxes (fold them up, if the white wax marks on the creases are particularly noticeable, or if you pinch the box gently, it will form a blob or crack).

In view of the disadvantages of covered lunch boxes, covered lunch boxes have been used in European and American countries, which were introduced to China at the end of 2016. Since 2017, high-speed railway lunch boxes have been basically replaced by covered lunch boxes. This kind of laminating food box sealed, not easy to spill not easy leakage, will not cause food flavor, great to keep the original taste of food. Not cause food contamination in transit, has good heat preservation effect, box the film easy to tear, safe use, convenience of our customers and no pollution, can be microwave heating, due to the nature of this color is white and laminating, boxes will not use recycle material and add the harmful material, bring consumers a sense of security, deeply consumer's heart, significantly increase the foreign consumers to sell shop high praise.

Actually existing types of boxes and there are many, such as paper boxes, boxes, corn starch based boxes, etc., but the mainstream boxes is given priority to with PP, I believe that with the progress of science and technology, there will be other material after lunch boxes, takeaway after no matter use which kinds of boxes, as long as the environmental, consumer health harmless, inexpensive boxes we will vigorously support, the stand or fall of a product is often determined by consumers and the market.
