The main raw material of such plastic products, such as containers and lids, is PET containing less than 10% by mass of antibacterial agents, and its antimicrobial activity is not less than 2.0. Its antimicrobial activity is sufficient to resist various microorganisms such as Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Candi. Da, yeast, Cladosporium, Aspergillus niger and so on. For example: RT543 (PET) with 1% antimicrobial agent Novaron AG is blown into a square bottle with good styling stability. Its antimicrobial activity is resistant to E. coli and Staphylococcus aureus. If Novaron AG's mass fraction exceeds 10%, the visibility of the contents of the bottle will be reduced due to increased bottle turbidity.
