中文摘要:
      目的 对莫斯利安酸奶包装进口复合阻隔片材进行国产化生产。方法 通过将塑料热成型片材挤出和软包装阻隔膜进行熔融粘合, 生产出复合阻隔片材。利用不同基材配方和厚度的PS片材与EVOH阻隔膜进行复合, 测定复合片材的力学性能、 成型包装性能、 阻隔性能和卫生安全性能, 并对测试合格的片材灌装产品进行稳定性试验。结果 EF400生产线采用复合阻隔片材PS/EVOH/PE, 总厚度为1200 μm, 其中PS (配方为mHIPS∶mGPPS=4∶1) 的厚度为1050 μm, EVOH的厚度为39 μm。PS的配方和厚度会影响复合片材的力学性能和成型包装性能。复合片材的卫生性能按照GB 9683进行测试, 样品型式、 浸泡条件和测试方法都会影响蒸发残渣值检测结果。结论 国产化复合高阻隔片材PS/EVOH/PE可以代替进口片材,保障莫斯利安塑杯酸奶的质量安全。
英文摘要:
      The aim of this study was to realize the domestic production of the imported barrier composite sheet for momchilovtsi yoghurt plastic packaging. High-barrier composite sheet was prepared by laminating flexible packaging barrier film with melted plastic extrusion sheet. EVOH barrier film was laminated with PS sheets with different ingredients and thickness. The mechanical property, thermoforming packaging property, barrier and sanitation properties of the composite sheet were measured, and the composite sheet packaging products which passed the tests were then subjected to stability test. The PS/EVOH/PE barrier composite sheet was applied to the EF400 filling equipment. The total thickness of the composite sheet was 1200 μm, among which, the thickness of PS was 1050 μm and the formula of PS was mHIPS∶mGPPS= 4∶1, while the thickness of EVOH was 39 μm. The ingredient and thickness of PS sheet could influence the mechanical and thermoforming properties of the composite sheet. The sanitation property of composite sheet should meet GB 9683. The sample type, migration test conditions and test method could influence the test result of evaporation residue value. Domestic production of high-barrier composite sheet PS/EVOH/PE could replace imported sheet to ensure the safety of momchilovtsi yoghurt.
