Why do American restaurants use cartons for packing and Chinese use plastic boxes? The main purpose of fast food is to facilitate people's life and solve the problem of daily food and clothing. No matter what kind of box it is, its purpose is to hold food. Such as American Chinese lunch box is a unique culture. Anyway, I haven't seen it in other capitalist new countryside... In fact, relatively speaking, plastic boxes are more popular. In foreign countries, fish and chips are usually packed in square boxes or plastic meal boxes. Why do American fast food like paper packaging? As a foodie, I think the main reason here is because of fried food. As we all know, frying can cause a lot of water loss in food. Even after it is out of the pot, a certain amount of water will still volatilize. If you don't place it in an open way, your chips will wilt in a short time. The cartons here are guaranteed to have a good ventilation effect, and they are relatively environmentally friendly. Foreigners, doing something is not environmentally friendly. Another way of saying is that there are more manual workers in China. The only requirement for manual workers to sell abroad is to have a large quantity and sufficient management. This is the main reason why plastic lunch boxes are widely used in China. If cartons are used, the bearing capacity of cartons will be affected if the capacity is large. If the cartons are thickened, the cost will be increased. Relatively, the flexibility of plastics is much better.
