Polyvinyl alcohol ( PVA) is a biodegradable, water-soluble polymer which has excellent biocompatibility, easy film formation properties and relatively simple preparation and it has been widely used in packaging area. This paper describes the performance characteristics of polyvinyl alcohol, degradation mechanism, the various factors affecting the degradation mechanism of polyvinyl alcohol and summarizes the preparation method and research results of polyvinyl alcohol ( PVA) biode-gradable material which modified by starch, modified starch, chitosan, polylactic acid. In the end, it indicates that PVA bi-odegradable film of low cost, excellent mechanical properties and completely biodegradable film is the research priorities. Also, the PVA/nanoclay high barrier packaging materials is the main point for research.
