The oligomer structures of non-toxic antimicrobial agents are well compatible with all polymeric materials, such as PP, PET and so on, the PP and PET added with oligomeric antibacterial agents exhibited excellent antibacterial property and having following characteristics: 

• Not migrating out away from polymers;
• Not leaching out as it’s bonded tightly with polymeric materrials;
• Not extractable from polymers;
• It’s NON-TOXIC and suitable to be utilized as food packaging and human living environment;
• It is benefited for recycle polymer materials.
• It is permanent antibacterial
