Films form a “barrier” emcompassing the product inside the pouch to prevent the material within the from outside environments and to prevent contamination.  Dependent on the pouch structure, the film is capable of inhibiting gaseous exchanges inwardly and outwardly, maintaining the product consistently fresh and ready for its intended use.
