AbstractPoly(vinyl alcohol) is known to have high moisture content and nontoxicity. In this study, chemically cross-linked poly(vinyl alcohol) hydrogel films were prepared by adding glutaraldehyde as the cross-linker. Cross-linked gels were chemically stable and resistant to heat. Antibacterial hydrogels were obtained by blending chitosan solutions with different concentrations. The value of Young's modulus of PVA hydrogel film increased with increasing chitosan content. According to the shake method (SIAA), these hydrogels exhibit antibacterial activity against Staphyrococcus aureus. These hydrogel films will be useful to the food packing material.
