摘　　要：采用不同材质的三种镀铝薄膜,在相同条件下,分别对三种镀铝薄膜的正反面进行氧气透过量和水蒸气透过量检测。结果表明:镀铝面朝向低压侧时的氧气透过量明显小于镀铝面朝向高压侧时的氧气透过量;镀铝面朝向低湿侧的水蒸气透过量明显小于镀铝面朝向高湿侧的水蒸气透过量。Three kinds of plastic films deposited with aluminium were used.With a same condition,the oxygen permeability and water vapor permeability of their both sides were tested.The results show that when the surface deposited with aluminium towards to the low pressure side,the oxygen permeability is significantly less than the one which surface deposited with aluminium towards to the high pressure side.Similarly,when the surface deposited with aluminium towards to the low humidity side,the water vapor permeability is obviously lower than the other one.
