Since the quality of life is improving, people have a more demanding requirement towards foods shelf life. And Huafeng is always dedicated itself to meet customers' requirement. All its packaging bags adopt plastic co-extrusion barrier films with an oxygen transmission rate smaller than 1 %, which helps to slow its metabolism. In this way, food's freshness and flavor will be better provided than other traditional packaging bags. Besides that, Huanfeng could also manufacture desired packaging bags or custom printed flexible packaging films according to required bag shape. These packaging bags and films all possess adequate hardness and high performance towards pollution. And they all underwent heat sealing and high temperature sterilization.
