In everyone's life will encounter many different forms of "sugar-coated cannonball", such as psychological, physical and so on.But there is a kind of want to experience everyday, and intensified.This is the "sugar-coated cannonball" food, food packaging bags.Food packaging is called "special food additives", it is the last procedure of the modern food industry, to a certain extent, food packaging has become an important part of an integral.But the food packaging industry in our country face the situation is not optimistic.So, for us, and how to do?
Ever seen such a report: DingXi County in gansu province is famous for is rich in high quality potato, potato chips in a food factory is listed, however, the factory in the quality inspection found a similar product in the family is decorated in a strange taste.By lanzhou university chemical laboratory analysis, the odor from the packing bag of potato chips.Lanzhou city pledges inspect bureau after analysis and testing, make sure the smell from the residue of benzene in the bag.Results show that the packing bags of chips of residual benzene exceed bid more than 3 times, exceeds bid badly.
