Abstract

Abstract

A compound antibacterial film was prepared by coagulation of sodium alginate (NaAlg) , sodium carboxymethyl-cellulose (CMC) , glycerin and kalium sorbic acid in aqueous solution, and the characteristic of film were evaluated by transparency, thickness, mechanical properties of film. The optimal constitution of compound antibacterial film was:sodium alginate 1. 5%, sodium carboxymethyl-cellulose 1. 5%, glycerol 1%, kalium sorbic acid 3%, and sodium alginate∶ sodium carboxymethyl cellulose=85∶ 15.
