초록 ▼

A flavor burst structure and a method of dispersing a flavorant are disclosed. The flavor burst structure comprises a multilayer film with a flavor carrier layer disposed between barrier layers. The flavor carrier layer comprises a polymeric material blended with a flavorant that is not compatible or is partially incompatible with the polymeric material so that the flavorant desorbs from the carrier layer when one of the barrier layers is removed from the carrier layer. Several package applications are disclosed, including a cigarette package, package tear tapes and the like.
