Abstract
A paperboard-based laminated structure for containers produced by co-extrusion coating or lamination of a polyethylene terephthalate layer as the product contact layer and a unique tie-layer on to paperboard, where the tie-layer is specifically ethylene-ethyl or butyl acrylate copolymer or terpolymer. This paperboard structure provides high temperature end-use performance required in dual-ovenable applications and cost savings.
