Concentration gradient refers to a phenomenon that accompanies active transport by using the concentration difference according to Fick’s diffusion law when a substance moves through a membrane in a cell. In the development of a barrier film for packaging using a biodegradable polymer film, we report a method of providing barrier properties by processing the composition of the plate-shaped filler to have a concentration gradient to prevent the permeation of oxygen or moisture. In addition, application of various barrier films with concentration gradient properties in multi-layered polymer films will be presented.
