    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.

    Abstract: A heat sealable paper-based substrate is provided with at least the first surface covered with at least one primer coat and at least one topcoat over the primer coat, wherein: the primer coat is formed from a substantially wax-free aqueous dispersion of at least one polymer or copolymer, has a coefficient of thermal expansion equal to or less than about 200 μm/(m·° C.) for at least one operating temperature, and has a complex viscosity of at least about 80000 poises at a heat seal temperature; the topcoat has a different composition than the primer coat and is formed from an aqueous dispersion of at least one thermoplastic polymer or copolymer, and has a complex viscosity of at least about 3000 poises at a heat seal temperature. The heat sealable paper-based substrate can be used to make articles to contain goods such as cold or hot beverages or food products.

    Abstract: There is provided a header for packaging a roll of paper having two opposite roll ends and an outer roll surface extending between the roll ends, the outer roll surface being wrapped with a wrapping paper. The header comprises a cellulosic fiber based substrate having two surfaces and a film coated to at least a portion of one of the substrate surfaces. The film is coated to the substrate surface by extrusion of a coating comprising a mLLDPE resin. The film coated surface is heat sealable to an outside surface of an interior header affixed to one of the roll ends, thereby forming a protective cap at the roll end. The header generates less volatile compounds and/or carbon monoxide compared to a header coated with a standard LDPE, on heat sealing conditions.
