PRODUCTION OF REGENERATED CELLULOSE FILM HAVING CHITOSAN ADHERED ON IT

摘要

PURPOSE: To obtain the subject film free from losing e.g. transparency of a film and capable of inhibiting the growths of a bacterium and a fungus on a material packed in the film by coating a chitosan solution on a regenerated cellulose film, condensing the solution and making the chitosan water-insoluble. ;CONSTITUTION: This antibacterial and antifungal film is obtained by coating a chitosan solution of a concentration of preferably ≤5wt.% on a regenerated cellulose film (preferable coating amount is 0.001-0.05g/cm²), condensing the solution to a water content of ≤20%, making the chitosan water-insoluble and then preferably allowing to absorb silver ion.;COPYRIGHT: (C)1995,JPO
