The antifungal PVA film was fabricated by addition of the clove oil/β-cyclodextrin inclusion complex into PVA, which is acted as the basic packaging material. The mechanical properties, oxygen permeability and the bacteriostatic action of the film varied with the additional amount of inclusion complex. The tensile strength of PVA film decreased with the addition of inclusion complex and the effect is little when the amount was less than 25%. Adding less than 25% had no obviously effect on oxygen permeability of the film. It proved that pure PVA films have no antibacterial property and the growth of aspergillus was inhibited in different degrees when the content was different. The growth range of aspergillus is smaller and the bacteriostatic action to aspergillus is increased with the increase of inclusion complex amount of agent. The inhibitory zone appeared when the inclusion complex amount was more than 20%.
