摘要
分析了食品包装薄膜透气性的测试方法和气体渗透性,并从单层包装材料的渗透性理论导出层合包装材料的渗透系数表达式,并设计了一个计算层合包装材料渗透系数的应用程序,并用单层材料的渗透性数据计算层合包装材料的渗透系数。
The gases permeability and its measuring method were analyzed. The expression of gases permeability coefficient of laminated packaging films was educed from single layer film and the corresponding computer program was built. The gases permeability coefficient of laminated packaging films was calculated from data of single layer by the program.
