Food packaging is an integral part of food commodities. One of the major projects in the food industry. It protects food and prevents the damage of biological, chemical and physical external factors during the circulation of food from the factory to consumers. It also has the function of maintaining the stable quality of food itself. It is convenient for food consumption. It is also the first to show the appearance of food and attract consumers. It has value beyond material cost. Therefore, the food packaging process is also an integral part of the food manufacturing system engineering. However, the universality of the food packaging process makes it have a relatively independent self system.
Why should we first introduce the specific concept of the word "food packaging"? It is mainly considered that in daily life, many people believe that they will ask whether disposable plastic lunch boxes can be reused and how long they can be used. The answers are also different. More people prefer not to reuse, which is not the case. This is why we should first introduce "food packaging".
As long as it is not used under high temperature, and every use is clean, it can be reused for countless times until it is broken Or you don't want to use it, but the premise is that the disposable plastic lunch box materials you use are food packaging grade.
