| 目的 为开发一种用于食用油的高阻隔抗紫外线(UV)功能片材，用于小容量食用油的泡罩包装，便于携带且方便一次性使用。方法 研究基于高阻隔塑料乙烯-乙烯醇共聚物EVOH，通过多层共挤和多层复合技术，得到一种4层结构的高阻隔片材CPP/APET/PE-EVOH/PE，通过电子万能试验机和气体透过率测定仪对片材的力学性能、水蒸气透过率、氧气透过率进行测定，并通过不同材料对比分析该材料在食用油包装中对食用油货架期的影响。结果 结果表明，片材的力学性能优异，水蒸气透过量为2.0 g/(m2.24 h)，氧气透过量为0.6 cm3/(m2.24 h.0.1 MPa)。该材料用于食用油包装，在温度45 ℃、相对湿度50%条件下贮存30 d后，橄榄油过氧化值的变化量为1.22 mmol/kg，远低于GB/T 23347—2009《橄榄油、油橄榄果渣油》中特级初榨橄榄油的上限值(10 mmol/kg)。结论 该高阻隔抗UV功能的泡罩包装可用于食用油包装，可减缓食用油氧化变质，并保留食用油原有香味。 |

| The purpose of this study is to develop a kind of high barrier anti-ultraviolet (UV) functional sheet for edible oil, which is easy to carry and easy to be used once. In this paper, a four layer high barrier sheet CPP/APET/PE- EVOH/PE was prepared by multi-layer coextrusion and multi-layer composite technology of high barrier plastic (ethylene vinyl alcohol copolymer EVOH). The mechanical properties, water vapor permeability and oxygen permeability of the sheet were measured by electronic universal testing machine and gas permeability tester. The effects of different materials on the shelf life of edible oil were compared and analyzed. The results showed that the sheet had excellent mechanical properties, the water vapor transmittance was 2.0 g/(m2.24 h), and the oxygen transmittance was 0.6 cm3/(m2.24 h.0.1 MPa). For edible oil packaging, after storage at 45°C and 50% for 30 days, the variation of the olive oil peroxide value was 1.22 mmol/kg, which was lower than the upper limit for extra virgin olive oil in the national standard GB/T 23347—2009 Olive oil and olive pomace oil:10 mmol/kg. The conclusion is that the new type of high barrier flexible packaging can be used in portable blister packaging of edible oil, which can effectively slow down the oxidation deterioration of edible oil and retain its original flavor. |
