Abstract: High－ intensity and low－ O 2－ permeability film was made of PVC resin andingvedienfs of nano－ TiO2 particles and other eleven types of Functional material. The O 2、 CO 2 and RH transmission rate of the film decreased 18％、 1.5％、 10％， respectively; and the elongation strenrth increased 36％ .This film has passed the test of national health bureau.‘ Fuji’ apples in the package of this film showed no CO 2 injury， and their firmness was 7.57kg/cm 2 after 208 days. The O 2 and CO 2 levels in the packaging were 3.1％～ 5.6％， 1.7％～ 2.6％， respectively.
