Abstract: To study the effects of pulse electric field treatment on the corn starch film-performance and the optimal process parameters, the multi-objective nonlinear optimization was adopted to demonstrate how electric field strength, pulse duration and pulse flow affect tensile strength, elongation at break, transparency, coefficiency of moisture vapor permeability, and surface microstructure, therefore, parameters applied to pulse electric field were optimized, revealing the fact that tensile strength and transparency were affected by pulse duration and pulse flow respectively.The main factor of elongation at break and coefficiency of moisture vapor permeability was the pulse intensity.With optimal processing parameters, 890 V/cm of pulse intensity, 85 μs of pulse duration and up to 62 pulses, the tensile strength, elongation at break, transparency and coefficiency of moisture vapor permeability were 1.03 N/mm², 62.34%, 1.339% and 0.10 g/ ( cm²·24 h) respectively.The result would provide a theoretical basis for the application and popularization of pulsed electric field in the production of corn starch film.
