Abstract
Described are antifog films useful for packaging food, and more particularly to antifog films that can be used as lidding films in trays made of amorphous polyester. The films may include at least one base layer or film, such as a polyester film, and a heat seal layer. The antifog layer is coated on the heat seal layer. The heat seal layer allows the antifog coating to more strongly adhere to the antifog film. The heat seal layer may be an amorphous polyester layer.
