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. Polyisobutylene is a preferred water-insoluble thermoplastic polymer, and hydrogenated wood rosin is a preferred polymer toughening agent. The polymer toughening agent decreases the tendency of the water-insoluble thermoplastic polymer to form legs or transfer to the food product upon stripping the laminate from the food product after cooking and transfer to the additive to the food product.

A multilayer film has a first layer and a second layer. The first layer comprises an additive, a binder, and a crosslinking agent.

The crosslinking agent comprises a compound with at least two carbonyl groups. The second layer comprises a non-water-soluble thermoplastic polymer comprising at least one member selected from the group consisting of polyolefin, polyamide, polyester, polyvinylidene chloride, polyvinyl chloride, and polystyrene. Each of the additive, binder, and crosslinking agent are present throughout a thickness of the first layer.
