What is Permeation?
Permeation is one of the indexes indicates the barrier properties in material field. In packaging material industry, permeation is used to state and evaluate the barrier property of packaging materials against water vapor, oxygen or other gases, etc.; that is, through the evaluation of water vapor transmission rate (WVTR) testing, oxygen transmission rate (OTR) and other gas transmission rate (GTR) testing of packaging materials, the basic guarantee for product quality and shelf-life period is confirmed. More questions for Permeation, please visit www.labthink.cn for answers.
