The work aims to provide a certain theoretical basis for preparation of polyvinyl alcohol films with good performance and environmental protection. The biomaterials reinforced polyvinyl alcohol film including chitosan, nanocellulose, degradable plastics, protein and its research status in food packaging were introduced as per classification.Although polyvinyl alcohol film with better performance can be obtained through modification by blending with different biomass materials, and it had the effects of antibacterial and anti-oxidation, smart labels and overall preservation when used as food packaging. Cost issues restricted the actual production. Biomass materials can enhance the comprehensive properties of polyvinyl alcohol films. It a good prospect in food packaging.
