Zusammenfassung:A packaging material for use in a package having contents including a food item, the packaging material includes a layer including an additive transformable from a first state to a second state in response to an external stimulus and a barrier layer positionable between said layer and the contents of the package. The barrier layer restricts diffusion of said additive to the contents. Cette invention concerne un matériau d'emballage destiné à être utilisé comme emballage pour denrées alimentaires, où ledit matériau d'emballage comprend une couche contenant un additif qui peut passer d'un premier état à un second état en réponse à un stimulus externe et une couche formant barrière qui peut être formée entre ladite couche et le contenu de l'emballage. La couche formant barrière limite la diffusion dudit additif vers le contenu de l'emballage.
