Misunderstandings in applications of flexible packaging for food mainly demonstrate in both of enterprises and consumers. The lack of profound research and recognition of flexible packaging for food, lack of study in the compatibility of packing material and food in application are the mistakes of the enterprises. On the other hand, consumers are deficient in knowledge about plastic flexible packaging which results in unscientific usage of such packaging. To solve these issues, new materials should be focused in future R & D such as multi-adaptive, oxidation resistant and edible materials while constructing safety management system and reinforcing the promotion of scientific usage of flexible packaging for food.
