Friends who often order takeout should have seen it. When the takeaway brother delivered the hot takeaway to his hand, he found that the plastic containers for the food usually have square, round, oval and other shapes, and different shapes are disposable. The food contained in plastic lunch boxes is also different. For example, round bowls contain soup noodles, sauerkraut fish and other foods with more soup, and square lunch boxes contain rice, vegetables, meat and other foods. Why is this? ? The editor of Huale Technology will tell you.
The food stored in different lunch boxes is also different. In addition to the common squares, rectangles, and circles, there are also suits designed for picnics, etc., mainly to make life easier and more convenient. Of course, when choosing different lunch boxes, you must pay attention to the materials used. Only the lunch boxes made of new PP materials are tasteless, non-toxic, resistant to high and low temperature, and harmless to human health.
Square packing box: good sealing performance, suitable for storing food, can prevent peculiar smell in the refrigerator, suitable for storing various seasonings, leftovers, leftover cans, fruits, vegetables. Easy to use in refrigerators, freezers, microwave ovens, and other uses.
Rectangular packing box: suitable for storing bacon, meat food, and easy to store food with moisture. The large-capacity rectangular crisper is suitable for preserving fruits, vegetables and seafood.
Round packaging box: suitable for long-term storage of various condiments, canned fruits, grains, nuts, tea and other foods, easy to use in refrigerators, freezers, and microwave ovens. The oval design is suitable for storing beverages, children’s milk and various grains, nuts and teas, etc. when traveling in the wild.
Large-capacity plastic round bowl: suitable for storing food such as lobster, hot pot, pickled fish, noodles, cucumber, etc. Since the height and size of the large-capacity plastic round bowl are higher than that of ordinary lunch boxes, the processing technology requires high mold size and mold removal. Therefore, there are not many manufacturers that can produce large capacity in the market, and there are relatively few products.
