The18th National Congress of the Communist Party of China is opening from November 8th to 14th. During this important meeting, one child ask a question: How could we get healthy food? In China, we pay more and more attention to food safety, but we also found that too many food are harmful. Sanlu toxic milk powder, poison cowpea, hogwash oil... we are surrounded by too many dangerous food. 

In fact, some food become harmful is because of the inferior food packaging bags. Unqualified raw materials, inks and glues could pollute the food. Some manufacturers donot sterilize before food packaging, then bacterias which adhere to the bags will also pollute food. 

Food packaging bag could also be some recognition means of good food. As we known, exquisite packaging bag would be much expensive than common packaging bags. We can presume that one company who care about the packaging would also care about the food safety.
