摘要
探讨了包装薄膜透湿的基本规律,并通过一些实验数据和现象,推导出各种膜透湿性的计算公式,以及同一膜材不同因数之间的换算公式,为包装整体设计提供了适用的计算方法。
This paper studies the basic law of the water vapour transmission though packaging film and derives the calculating formula for the water vaper transmission of various films as well as the interrelation among different factors based on some experimental data and phenomena, providing a practical calculation for packaging design.
