Southwest Jiaotong University successfully developed Zn0 crystalline composite antibacterial agents and used them in plastic packaging substrates to develop antibacterial packaging materials with antibacterial rates of more than 99%.

Due to the unique colorless characteristics of the Zn0 crystalline composite antibacterial agent, the color of the substrate is not changed in the substrate, therefore, transparent polycarbon and polyethylene antibacterial materials can be made. In addition, due to the Zn0 crystal state itself, Multi-functional characteristics, plastic packaging materials added Zn0 crystalline composite antibacterial agent also has special features such as high strength and good preservation. In addition to plastic packaging, Zn0 crystalline composite antibacterial agent can also be used for surface coating of paper packaging and metal packaging. The launch of this antibacterial packaging material has attracted the attention and interest of a number of packaging material companies. At present, the product has applied for a patent for invention.
