An additive delivery laminate is suitable for packaging a food product which is cooked in the package, with an additive transferring from the laminate to the food product. The additive delivery laminate has a substrate and an additive delivery layer. The additive delivery layer contains a water-insoluble thermoplastic polymer, a polymer toughening agent, and additive granules containing a colorant, flavorant, and/or odorant. The polymer toughening agent is present in a blend with the water-insoluble thermoplastic polymer.
