摘要
对影响铝箔复合软包装材料阻隔性能的因素进行了探讨 ,指出了关于铝箔复合膜阻隔性的一些误区 ,对铝箔针孔与铝箔复合材料阻隔性能的关系进行了理论推导 ,得出了理论公式 ,并利用公式讨论了BOPP、PE等材料的厚度对铝箔复合材料阻隔性能的影响。文章还对铝箔复合软包装氧气透过率和水蒸汽透过率的检测进行了比较分析 ,指出了目前测试中存在的一些问题。文章最后还从包装、运输、销售的全过程出发 。
The factors affecting the barrier performance for Aluminium foil laminated films were discussed and some wrong viewpoints about barrier performance for foil laminated material were pointed out. The relations of foil pinhole and barrier performance of foil laminated films were studied and theoretical expressions were deducted. The influence of the thickness of BOPP or PE to the barrier performance of foil laminated films was discussed with the deducted expression. The test methods of oxygen and moisture permeability were analyzed and found to have some problems. It was suggested that we should study the whole course of foil laminated package, from manufacturing,packaging,transport to sales, and then, we can get the real and reliable barrier performance of the package.
