"WebCrystallinity is a measurement of the degree of structural order of the molecules in a polymer. It has an inverse relationship with the permeability of polymer composites. The mass transfer of a gas or aroma in a semicrystalline polymer is primarily a function of the amorphous phase, resulting in the permeation of the gas or aroma. " - Crystallinity of denim
