I-masterbatch ikhiqizwa ngokuxhunyelelwa i-organic antimicrobial agent (i-polyguanidine salt) kumapulasitiki ngezigaba eziningi ze-polymerization nokuguqulwa.Amafilimu e-antibacterial, amabhodi neminye imikhiqizo yepulasitiki ingenziwa ngokungeza kwangaphakathi i-masterbatch.Uma kuqhathaniswa namapulasitiki e-antimicrobial angaphili (isiliva, ithusi, i-zinc oxide), lo mkhiqizo unesivinini esisheshayo se-antimicrobial kanye nomphumela omuhle wokuvimbela isikhunta negciwane.
