<p>A dual ovenable food product container is formed from a coated or uncoated paperboard substrate to which is applied a precoat layer and a topcoat layer. The precoat is formed from an aqueous emulsion copolymer such as ethylene vinyl acetate while the top coat is formed from an aqueous emulsion which is a copolymer of one or a mixture of styrenated acrylic copolymers. The Tg of the precoat should be in the range of 0 °C to 25 °C, while the Tg of the top coat layer is in the range of about 10 °C to 60 °C.</p> |
