Abstract
A laminate for coffee packaging is defined. The laminate includes an inorganic gas barrier layer, a strength layer, and an energy cured coating. The laminate provides as good or better barrier properties as a conventional laminate for coffee packaging. However, the laminate of the present invention has non-migratory, “reacted-in” slip agents. Further, the new laminate is more economical to produce than is the conventional laminate.
