The difference between the types of fast food packaging

There are many kinds of fast food packaging materials used, and fast food packaging has been developed for many years. And each packaging material has different problems of one kind or another. Recently, at the National Chemical Industry Conference, researchers showed a new packaging material that can improve the quality of fast food packaging, reduce packaging prices, and be more environmentally friendly. The packaging material originally used in fast food packaging is polystyrene wrapping paper, which is easy to manufacture and can effectively keep food warm, but it is insufficient because polystyrene contains chlorofluoro compounds that pollute the air and Not biodegradable. Therefore, the increased awareness of environmental protection has prompted the fast food packaging industry to find new products. Fast food packaging paper materials have changed from polystyrene to cardboard, but cardboard still has many shortcomings, such as high cost, cumbersome manufacturing process, and inconvenient transportation due to weight reasons. The biggest shortcoming is: the food cannot be kept warm effectively.
