Diffusion coefficient represents molecular transmission capacity through film because of thermal motion of molecular chain. Diffusion is derived from the mass transfer process of molecular random motion and it is a phenomenon that particles (molecules, atoms) gradually transfer from their original position by micro random motion. In the field of flexible packaging testing, diffusion coefficient is a major parameter for prediction of product quality guarantee period.
