植物油类调味品防漏油包装材料及措施探索

目的 寻找合适的植物油调味品包装材料、试验配件，以获取热封压力范围，解决植物油调味品行业实际生产中产品包装漏油问题。方法 采用PA15/PE62，PA15/PE65，PA15/PE55，PET/PET镀铝/PE，PET/Al/PE，PET12/PE38等7种包装材料，在使用自动制袋式填充包装机实际生产环境下进行50，150，300 g等3种规格的清油类底料灌装，并施加30 kg重物进行90 d储存试验，每隔15 d观察包装的封口质量；添加热封压力调节配件，在实际生产中可间接指示热封压力范围，进而探索不同材质的热封压力调节范围。结果 在进行了90 d压力储存后，发现3种规格的样品包装材料漏油率在0~17.95%之间，其中PA15/PE62在50，150，300 g等3种规格下的漏油率均为0，可见该材质在现有生产条件下能够有效缓解漏油现象；该压力配件效果较好，得出2种卷料的热封调节配件调节圈数集中在7.4~6.25圈，7.4~5.75圈。结论 PA15/PE65能有效缓解实际生产中的热封部位断根现象、漏油现象；该压力配件的使用便于生产企业找寻热封压力与热封温度的平衡点，进而缓解漏油现象。

Exploration of Oil Leak-proof Packaging Materials and Measures for Vegetable Oil Seasoning

The work aims to find suitable packaging materials and test accessories for vegetable oil condiments, obtain the heat sealing pressure range to solve the problem of oil leakage in product packaging in the actual production of vegetable oil condiments industry. Seven kinds of packaging materials including PA15/PE62, PA15/PE65, PA15/PE55, PET/PET aluminized/PE, PET/Al/PE and PET12/PE38, were used to fill oil base materials of 50 g, 150 g and 300 g in the actual production environment of automatic bag-making packer, and 30 kg heavy materials were stored and tested for 90 days. The sealing quality was observed every 15 days. By adding heat seal pressure adjusting accessories, the range of heat seal pressure in actual production could be indirectly indicated, and then the range of heat seal pressure adjusting of different materials could be explored further. After 90 days of pressure storage, the oil leakage rate of three packaging materials ranged from 0% to 17.95%. The oil leakage rate of PA15/PE62 under three specifications of 50 g, 150 g and 300 g was 0, which showed that the material could effectively alleviate the oil leakage under the existing production conditions. The pressure accessories had better effect and the number of adjusting cycles of heat seal adjusting accessories of two coils was 7.4~6.25 and 7.4~5.75 respectively. PA15/PE65 can effectively alleviate the phenomena of broken roots and oil leakage in the heat-seal parts in actual production. The use of the pressure accessories is convenient for manufacturers to find the equilibrium point between the heat-seal pressure and the heat-seal temperature, thus alleviating the oil leakage.
