Abstract: A foldable paper-based substrate coated with primer coat and top coat. Primer coat comprises a wax-free aqueous dispersion characterized in that a dry film thereof has a flexibility of at least 1 100% for a film thickness from about 1.0 to about 2.5 mm. Top coat is blocking resistant and comprises an aqueous dispersion of a polymer providing water resistance, grease or oil resistance, heat resistance, odor barrier, moisture barrier and/or heat sealability to the paper-based product. The top coat aqueous dispersion is characterized in that a dry film thereof has a flexibility of at least 570% for a film thickness from about 1.5 to about 2.5 mm. A process for preparing the coated foldable paper-based substrate comprises applying the primer coat to the surface of the paper-based substrate, applying the top coat and drying the coats. The primer coat may be dried before application of the top coat.
