CA 2049271

An extruded film article such as a bag comprises a blend of a thermoplastic polymer such as ethylene vinyl acetate and an olefinic oxide polymer such as poly (ethylene oxide), with a modifier such as liquid smoke absorbed in the blend. The modifier is transferable from the film to a receiving surface such as a food body in fluid transfer relationship with the film.

Une pellicule extrudée, comme une pellicule formant un sac, comprend un mélange d'un polymère thermoplastique, comme de l'éthylène-acétate de vinyle, et un polymère d'oxyde d'oléfine, comme le poly(éthylène oxyde), avec un modificateur, comme de la fumée liquide, absorbé dans le mélange. Le modificateur est transférable de la pellicule à une surface réceptrice, comme un aliment, qui est en contact avec la pellicule, établissant ainsi une relation de transfert de fluide.
