Abstract

The paper aims to research and select packaging materials of good flexibility and permeability to ensure the long shelf life and good quality of fresh fruits and vegetables. Six film samples of different structures and different thicknesses were used in O2 and CO2 permeability tests performed at 25 ℃, 90% RH and 5 ℃, 90% RH, as well as the tensile force test at break and pendulum impact energy test before and after cold storage. The six samples had higher O2 and CO2 permeability at 25 ℃ than 5 ℃. The order of permeability was 2#>3#>4#>5#>6#>1# for the six samples under the two test conditions. Sample 1# had good flexibility. Sample 4#, 5# and 6# had low strength and uniformity flexibility. The strength of modified 2# and 3# samples was improved, with decreased flexibility. The flexibility of sample 1# after cold storage was increased slightly, but the flexibility of sample 4#, 5#, and 6# decreased after cold storage. The structure, thickness and modification methods may affect the performance of the packaging film. Fresh fruit and vegetable producers shall keep monitoring the properties of the packaging materials based on factors such as the characteristics of the fruits and vegetables, shelf life and storage conditions, so as to select suitable packaging materials for their products.
