QB/T 1871-1993标准中水蒸气透过量与其厚度的关系研究

Study on the Relationship between Water Vapor Transmission and its Thickness in QB/T 1871-1993 Standard

通过测量大量不同厚度的BOPA/LDPE复合膜的水蒸气透过量,利用Excel软件进行拟合两者关系式,可方便生产企业通过测量样品厚度来估算其水蒸气透过量。

Through test the water vapor transmission of a large number of BOPA/LDPE complex flms with different thickness, and fit the relationship between them by Excel software. It is convenient for manufacturers to estimate water vapor transmission by measuring the sample thickness.
