The Institute of Materials Science and Engineering, Southwest Jiaotong University, has successfully developed a ZnO (zinc oxide) crystal composite antibacterial agent. Based on this, it has successfully applied it to plastic packaging materials and developed antibacterial packaging with an antibacterial rate of 99% or more. bag.
According to reports, due to the multifunctional nature of the ZnO crystal itself, the plastic packaging material added with the ZnO composite antibacterial agent also has the characteristics of high strength and good preservation performance. In addition to this plastic package, it can also be used for surface coating of paper packaging and metal packaging. The use of the above packaging materials for food can greatly extend the shelf life of food.
