WebPermeation is the movement of a gas or vapor through a semi-permeable barrier such as the wall of a film, whole package, medical device, or even a flexible electronic display. The gas … In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter.
