Abstract: This article reviewed the recent research and manufacturing progresses of biodegradable grade biaxially oriented poly(lactic acid) (BOPLA) film, and intensively introduced two class biodegradable grade BOPLA films processed by basic and functional types. Moreover, the biaxially oriented processing technology in the improvement of resin matrix formulation, stretching temperature, stretching ratio, stretching rate and heat setting temperature as well as the introduction of method based on metallization technology of surface layer for the preparation of biodegradable grade BOPLA film were also introduced. Finally, development trend of biodegradable grade BOPLA film was prospected.
