This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.
