Iyo masterbatch inogadzirwa kuburikidza nekubatanidza organic antimicrobial agent (polyguanidine munyu) mumapurasitiki nematanho akawanda epolymerization uye gadziridzo.Antibacterial mafirimu, mabhodhi uye zvimwe zvigadzirwa zvepurasitiki zvinogona kugadzirwa nemukati wekuwedzera masterbatch.Kuenzaniswa ne inorganic antimicrobial mapurasitiki (sirivha, mhangura, zinc oxide), chigadzirwa ichi chine kukurumidza antimicrobial kumhanya uye yakanaka inhibitory mhedzisiro pafungi uye hutachiona.
