Abstract:: PE/OPP/PE composite film，PE film and corona processing PE film were used as test materials.Passive air conditioning package which had an initial gas ratio of 21% O2+09% CO2 was adopted.The effects of different air permeability，moisture permeability of the film on preservation effect of strawberry modified atmosphere were studied.The results showed that under the condition of room temperature（15±2）℃，relative humidity 33%-35%，PE/OPP/PE composite membrane maintained high sensory evaluation and hardness of strawberry，corona treatment of PE film was more conducive to delay the decline of soluble solids and the increase of pH.The effect of PE/OPP/PE composite film and corona treatment on the preservation of strawberry was better than that of PE film during the 6 days of storage.
