A laminate for gum packaging is defined. The laminate includes a metal layer, a polymer layer, a paper layer, and an electron beam cured coating. The laminate provides as good or better barrier properties as a conventional laminate for gum packaging. However, the laminate has "reacted-in" slip agents in the electron beam cured coating, thereby avoiding the common problems of slip agent migration. Further, the laminate of the invention is more economical to produce than is the conventional laminate.

L'invention décrit un laminé pour conditionnement de gomme. Le laminé comprend une couche métallique, une couche polymérique, une couche en papier et un revêtement durci par faisceau d'électrons. Le laminé fournit des propriétés barrière égales ou supérieures à celles d'un laminé conventionnel pour conditionnement de gomme. Toutefois, le laminé comporte des agents glissant « à réaction interne » dans le revêtement durci par faisceau d'électrons, évitant ainsi des problèmes courants liés à la migration d'agents glissants. De plus, le laminé décrit dans l'invention est plus économique à produire que le laminé conventionnel.
