摘要: 试验以 SG— IV型 PVC树脂为主料,填加含有纳米粒子的 TiO2母粒和其它 11种功能材料,研制出高强度的阻 O 2纳米富士苹果保鲜膜,经国家测试中心测定纵向拉抻强度提高 36%,透 O 2率降低 18%,透湿率降低 10%, CO 2渗透率仅变化 1.5%,并通过国家卫生检验。使富士苹果 0.03mmPVC小包装扎口于 0~ 1℃下贮藏 208天,无 CO 2伤害,果肉硬度达 7.57kg/cm 2,保持袋内 O23.1%~ 5.6%, CO21.7%~ 2.6% .

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.
