With three different concentrations (0.1%, 0.15%, 0.2%), the ethanolic extract of Rosemary was sprayed on the surface of low density polyethylene films (LDPE). Films without extract was used as control. Phenolic compounds migration from the surface of film to 95% ethanol (fatty food stimulant) was measured at 4ºc during 10 hours. With increasing time and extract concentration, migration to ethanol increased (P
