Additive delivery laminate containing styrene-ethylene/butylene-styrene copolymer

摘要

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 styrene-ethylene/butylene-styrene copolymer and additive granules containing a colorant, flavorant, and/or odorant. The styrene-ethylene/butylene-styrene copolymer has a styrene to ethylene/butylene weight ratio of from 5:95 to 50:50 and a Brookfield Viscosity of from 500 to 100,000 centipoise measured as a 25 weight percent solution in toluene at 77° F.
