摘要

This experiment explores changes of peroxide value and acid value of the edible oil that is over-wrapped with BOPP/VMPET/CPP composite film and then stored at 35 ℃, 50% RH, and predicts the shelf life of edible oil under this condition by means of dynamics equation. At the same time, the barrier property of the film was evaluated by measuring the initial permeability and moisture permeability of the film and the tensile properties at different time periods. Research shows that peroxide value and acid value in the edible oil increase with time linearly, tensile properties of the soft package decreased gradually with time. Under the experimental conditions, the oil packed in BOPP/VMPET/CPP composite film had a shelf life of about 70 days, far below that of polyester plastic bottle packaging in the market for sale, so the application of flexible packaging in edible oil still need to explore.
