The increased use of polymer films to package a wide range of flavor compounds in various products creates a problem in trying to recommend appropriate materials. There is a need to identify tools that enable the engineer to simplify the selection process through ranking the relative adsorption of such compounds with different polymer films. The study of one such compound, Methyl Salicylate, was conducted for polymer films representing commodity and engineering barrier films. The films tested were Polypropylene, Polyethylene Terephthalate, Polyethylene Napthalate, Aclar, and Liquid Crystal Polymer. The testing was conducted with a Thermogravimetric Analyzer to determine the relative amount of penetrant adsorbed by each film; thereby enabling a ranking of expected barrier performance. The results indicate that the Liquid Crystal Polymer (LCP) film sample had the lowest rate of adsorption of Methyl Salicylate. Further studies are recommended to refine the method and evaluate multiple flavor adsorption behaviors.
