Patent ID: 7183006

Claim:
A multilayer additive-transfer film suitable for cook-in processing of food products, comprising: (A) a first layer, comprising (i) a binder comprising at least one member selected from the group consisting of polysaccharide and protein, and (ii) a crosslinking agent comprising a compound with at least two carbonyl groups; (B) a second layer, comprising a non-water-soluble thermoplastic polymer comprising at least one member selected from polyolefin, polyamide, polyester, polyvinylidene chloride, polyvinyl chloride, and polystyrene; and (C) a third layer, comprising (i) a binder comprising at least one member selected from the group consisting of polysaccharide and protein, and (ii) an additive comprising at least one member selected from the group consisting of flavor, fragrance, colorant, antimicrobial agent, antioxidant, chelating agent, and odor absorbent, said additive being bound to said binder with at least one member selected from a covalent bond, an ionic bond, a hydrogen bond, and a dipole-dipole interaction; wherein, the first layer is positioned between the second and third layers; and during cooking of a food product surrounded by said multilayer additive-transfer film, at least a portion of said binder and said additive in said third layer are transferred from said third layer to the food product.
